Review: Oasis One-Twelve Hydration System
You will find nothing but glowing reviews for these high-priced products. Which is as it should be: If you ignore cost, nearly all of these products truly are among the best available. Unfortunately, most top reviewers are either wealthy, work for a bike shop, or are reviewing a product sample, so they tend to discount the purchase cost in their reviews.
It takes extra effort to determine that some lower-cost products give up nothing significant (perhaps a tiny bit of style or weight), yet save 50% or even 80% of the cost. A common thread in many of my posts, particularly this one, is that I consistently advocate a value-based ("frugal") approach to triathlon, including not only equipment, but also things like training costs, supplements, and race fees.
For example, the $60 TCSD annual membership fee is easily the very best value in all of triathlon. The return on investment is so stunning, so overwhelming, that all other purchases are rip-offs in comparison.
Then there are those rare, unique, specialized products for which there literally is no competition. My personal example is my TitanFlex Al-Ti bike, the only product of its kind available that permitted me to continue in triathlon despite my bad back, and what's doubly amazing is that the TitanFlex is competitively priced.
Between the stratospherically-priced luxuries, the almost-free stuff, and the one-of-a-kind items, is a sea of products that offer varying levels of value compared to their competitors. Some of these products battle it out on the national stage, using marketing money to sponsor athletes and buy advertising in magazines and online. Other products eke out a meager existence with minimal marketing, selling one at a time here and there, relatively unknown and thus easily overlooked.
Among the minor players is the occasional gem of a product that deserves much wider recognition. The Oasis One-Twelve Hydration System is one such product.
Bicycle Hydration System Overview:
My involvement with "bicycle hydration systems" (a fancy name for anything on a bike that holds fluids that isn't a generic bike bottle) started when I got my Profile Design Airstryke clip-on aero bars, and saw how perfectly the Profile Design Aerodrink bottle fit between them. For most of my rides I would use it alone, without additional bike bottles.
For longer rides, many riders add bike bottles behind the seat. A large number of rear bottle mount systems exist, including the Beaker Concepts HydroTail, the Xlab Carbon Wing, and several systems by Profile Design. Rear-mounted bottles offer not only additional volume, but also provide improved aerodynamics when used instead of traditional frame-mounted water bottles. Many riders also find rear-mounted bottles are easier to access while pedaling.
After my back went out last year, I was no longer able to use a regular bike bottle: My weak back made it difficult to ride one-handed while holding a bike bottle, and also made it difficult to twist to the side to drink from one. On longer rides, I would use the time spent at stop lights to transfer water from my bike bottles to my Aerodrink bottle. This would clearly be impractical for non-stop rides and races, so I started looking into hydration systems that would allow me to drink from a tube, hands-free.
The simplest hydration system, and also the least expensive with the largest volume, is the popular hydration backpack, of which several bike-specific versions are available from a wide variety of manufacturers. While I find such systems ideal for use when riding upright, I haven't found a way to comfortably wear one while hammering in the aero position. There are front-mounted hydration packs designed for precisely this situation, but I doubt they'd be comfortable when riding upright, and they could block some ventilation on hot rides. Plus, I wouldn't want to take the time to put on a hydration pack during a triathlon transition.
Alternatives to hands-free bar-mounted and backpack hydration systems include frame-mounted and rear-mounted (behind the seat) systems which have tubing that runs from the reservoir to the bars. The best-known player in the frame-mounted hydration system market is the Inviscid Design Speedfil system. A less well-known rear-mounted system is the NeverReach Pro. The best prices I found for the smallest sizes of either system were around $100, including any required mounting kits and accessories.
While the Speedfil works great on regular "triangle" bike frames, it was not compatible with my monocoque TitanFlex. I also didn't like the idea of having to suck water up almost three feet vertically: It's like sucking on a milkshake, but getting only water for the effort.
The NeverReach has its own problems, the greatest being that it is not compatible with my ISM Adamo Road saddle. Another problem is that no local retailers carry it, so I couldn't check out the build quality. There were some unfavorable comments online concerning the mount, and I was unable to tell if it was due to the design or if the user either installed it or used it incorrectly.
The Oasis One-Twelve:
I made the rounds of my local bike shops to see if they knew of any systems I had missed. When I described my problem to Rachel at Moment Cycle Sport, she pointed to a system on a shelf behind the counter. It was the Oasis One-Twelve. And it was love at first sight.
The Oasis One-Twelve is the brain child of inventor and Ironman triathlete Dean Sprague, a prominent figure on the San Diego triathlon scene. The Oasis One-Twelve is named after the 112 mile bike leg of an Ironman triathlon.
I think it should be called the Oasis Sixty, since the system holds 60 ounces of fluid. The fluid is held in a pair of 30 ounce lightweight bike bottles that will fit in any rear-mounted bottle rack. The best part? The system costs under $40, less than half the price of any competitor's system.
The Oasis One-Twelve has a downside: It does not include the rear-mounted bottle rack, where the other systems mentioned above do include the mount. I looked at the rear-mounted racks previously mentioned, and they all cost well over $50, which would make the Oasis One-Twelve more expensive than the other systems. But once again Moment had a winning alternative: The $22 Tacx T6202 seat clamp. Combined with some spare bottle holders I had at home, it would work perfectly.
System Overview:
The Oasis One-Twelve system consists of the previously mentioned pair of 30 ounce water bottles, each of which has been modified with the addition of a 90 degree angled fitting at the bottom. The system also includes lots of tubing, an upper tubing stiffener, bite valve, and a generous length of Velcro strap material.
Surprising for such an inexpensive system, also included is a tubing cleaning tool. The separate Camelbak cleaning kit, for example, costs $10.
Installation:
Installing the Oasis system was simplicity itself: Put the bottles in the rack, route the tubing, cut it to length, then cut the long Velcro strap to the number and lengths needed and apply. There are no screws or clips, so the system may be removed just as quickly and easily as it was installed.
I didn't cut the tubing until after I knew I had the length right: I initially installed it with the extra tubing in a loop, then took a quick (dry) test ride to ensure I could position the bite valve where I wanted it before making the final cut. If you make a mistake and cut the tubing too short, a union is included to rejoin the tubing. If you do it twice, replacement tubing is available for a small fee.
The above installation description assumes the rear rack is already in place, and is able to handle a load of 60 ounces of water. The Tacx seat clamp is made of fiber-reinforced plastic, and when mounted per the Tacx instructions it sags and bounces under the weight of the filled bottles.
The Tacx instructions have the clamp extending horizontally from the rear of the seat, placing the tall bottles far behind the seat, with them extending well above the seat, which makes getting a leg over a bit more difficult. Simply flipping the clamp over makes it extend down instead of back, which not only eliminates sag and bounce, it also places the tops of the tall bottles at a much more reasonable height.
The adjustment to the mount created some slack in the tubing, so rather than cut it again, I'm riding with a small loop. Just in case I decide to change the mount someday.
Once everything was in place, I added a tie-wrap around the neck of the bottles and through the bottle cages to ensure the bottles would not bounce out even on the roughest road, or while on my rather bouncy car rack. The installation instructions suggest using some of the provided Velcro strap for this, but the circumference of my TitanFlex frame used up too much. It would never be a problem on bikes with a conventional frame geometry.
Here's a shot of the final installation, along with the Aerodrink bottle (click on the image for more detail):
One side-effect of the installation is that I could no longer use my under-seat tool bag. Some folks are able to mount their tool bag vertically against the seatpost, but mine wouldn't fit due to the tubing from the bottles. My solution was to build a bike bottle tool box, which will be the topic of an upcoming blog post.
Test Ride:
On my first ride with the filled system, I had trouble getting water from the bottle to my mouth. After checking that I had not pinched the tubing by making any of the Velcro straps too tight, a quick email to Dean revealed I had missed a note in the manual: The bottle cap valves need to be opened slightly to prevent a vacuum from developing. With that done, drinking from the system was effortless on subsequent rides.
The bite valve works very well. I found it has an interesting feature: Bite too hard, and you get no water. I have chewed through several Camelbak valves, and I look forward to getting longer life from the Oasis One-Twelve bite valve.
The sheath around the upper portion of the tubing is flexible enough to allow the bite valve to easily be positioned as needed, and is stiff enough to prevent the tube from whipping in the wind and hitting me in the face while in aero. I much prefer it to the plastic straw in my Aerodrink bottle, which cuts into the roof of my mouth if I hit a bump while drinking.
Conclusion:
The Oasis One-Twelve system falls into the "Insanely Great" category of my triathlon equipment purchases. I found absolutely no design or manufacturing flaws in the system. It is made from top-quality materials, and best of all, it costs less than all other equivalent products.
If you are looking for a hydration system, be sure to check out the Oasis One-Twelve before buying anything else.

"They're RACING flats dammit, not TRAINING flats!"
Hi Pete,
It's been 4 weeks since I broke a 2nd metatarsal running on hard surfaces in my racing flats. I got my flats in early September in preparation for my first-ever Olympic-distance triathlon (1.5K swim, 40K bike, 10K run). The shoes (Saucony Kilkenny) gave me the Winged Feet of Mercury, immediately slicing 30 seconds per mile from my 4 mile training runs, taking me to a 9:00 PR pace for the distance (with rolling hills).
My last prior 10K was nearly 25 years ago (I'm now 54). I stopped running when the pain in all my leg joints didn't go away for days after even mild training runs. I was a hard heel-striker then, with flat feet, skinny weak ankles, and slightly bowed legs. Getting into triathlon 2 years ago meant I needed to find a new way to run.
First I went with shoes that would keep the road as far from my legs as possible (Mizuno Wave Creation 10), which made a return to light running possible. But I was physically unable to go much faster than a fast jog. I added orthotics, which helped a little. Then I got knee pain (chondromalacia caused by ITB Syndrome), and I searched for a new stride. I read about POSE and Chi Running, adopted a mid-sole strike, and 3 months later my PRs started to improve, though they soon topped out again.
Then in August of 2009 I lost my L5-S1 disc: It simply degenerated away, leaving no padding and lots of pain behind. Since I had by then become addicted to each of the triathlon sports, I refused the offered spinal fusion surgery and endured months of physical therapy to learn how to live with a damaged back. And in February of this year I became a forefoot runner: Any significant heel contact would cause intense pain at the site of my degenerated disc, so I had no alternative, since I refused to give up running (and triathlon).
My initial web searches failed to uncover any useful forefoot running resources. I had to feel my way into forefoot running on my own. The first thing I noticed was that the towering heel of my Mizuno Wave Creation 10 was hitting the ground way too early, and was forcing me to run either on my tip-toes or in a slight squat in order to avoid a painful heel impact, each of which caused other problems.
I switched to a cheap pair of Asics that had a much softer and slightly lower heel. By mid-summer my PRs again started to improve. Since I wasn't placing as much weight on my midfoot, I removed the heavy orthotics, and saw another improvement in my PRs. At this point, I was much more comfortable running a mile than walking one!
When a friend suggested racing flats, I went to each of my local specialty running stores, tried everything, and when I finally tried the Kilkenny, it was love at first step. I got the shoes, trained well, did my race, beat my optimistic goal time, and kept on running in my racing flats. I searched the local shops for road shoes that would have a low heel compatible with a forefoot strike, but found nothing that fit my narrow flat foot.
In hindsight, a stress fracture was inevitable. Sure, it was not smart to run exclusively on hard surfaces in racing flats. But I also must share some blame with the shoe market, for not having a road trainer available that would fit my foot and running style, and also be stocked by local shops.
I somehow didn't find your blog until today, when I was again searching for road shoes. I've read a dozen of your general posts, and am working my way through your shoe reviews: We appear to generally think alike regarding technique and equipment, though we approached our beliefs from very different paths.
While I now consider myself to be a minimalist runner due to my forefoot stride, I also realize I'm a 'maximalist' runner: Maximally ignorant, that is. It took me way too long to learn the running vocabulary, which is the only way to get useful search results (when entering any area of specialization, first becoming 'buzz-word compliant' is mandatory). Where are the running glossaries?
I've reached the point where I'm willing to believe that my ideal road shoe, a padded racing flat, may simply not exist. And I'm wondering what I can do about that situation. So far, I've come up with five options:
1. Accept the situation: Do what's needed to adapt to the best fitting shoe available that has an acceptably low heel-to-toe (H2T) drop. But I'm concerned I'll have to adapt my stride to the point that I'll have problems switching back to my racing flats before races. And I refuse to give up my racing flats!
2. Find a shoe that's ideal in all respects OTHER than H2T drop, and have a cobbler slice away some foam to remove the excess heel height (a trivial task for any qualified cobbler). This would require a shoe with minimal heel structure, lacking things like wave plates and air/gel layers. The Brooks Green Silence may be a candidate, which I'll try out after my foot finishes healing.
3. Eliminate all hard-surface running, except for final race training and race day. Which means I keep running in my racing flats, but only on sand and turf. Not an easy thing to accomplish in my densely packed suburb, but not impossible (just impractical).
4. Add a thin Sof Sole gel cushion to the forefoot of my racing flats. I've already done this, just for insurance, but I doubt it is enough to prevent another stress fracture. And I haven't yet run in the modified shoe, so it may prove unworkable.
5. Create my own shoe.
As I've wailed and moaned about my shoe situation to friends, family, and members of the Triathlon Club of San Diego (TCSD, the Best Damn Club on the Planet, no lie), I found some kindred souls, one of whom is a mechanical engineer, and another who is a materials engineer with deep knowledge of polymers and foams. Me, I'm a software engineer with lots of simulation experience, and I also know my way around a sewing machine.
Unfortunately, we're all either lazy, time-crunched, or both, and would much rather work with an existing manufacturer than go off on our own. We simply want the shoes we want, and don't necessarily want to get into the shoe business.
Yes, I'm finally getting to the point:Some questions for you!
- What do you think of my options above? Did I miss any?
- Does my dream shoe already exist?
- What would you like to see in a new minimalist shoe suitable for forefoot road runners?
- Which manufacturers do you think would be most willing to work with motivated amateurs?
We've also discussed a shoe with a negative static H2T drop that would become zero when the forefoot sole is compressed. The shoe design would vary not only by foot size, but also by runner weight (possibly by swapping the insole). This would allow us to add sophistication to the forefoot without having to thicken or complicate the heel. It would be a shoe designed exclusively for forefoot hard-surface runners, though we might also be able to market it as a butt-lifting, leg-toning walking shoe!
Time for me to get back to reading your blog. Thanks!

Back in the game...
I have a friend who is a strength and conditioning coach with whom we were doing some circuit training. One circuit being a dumbbell clean & jerk.
Well....i believe this was the motion that has now left me almost immobilized.
At work today only because i work in an office environment.
I have the SDIT this Sunday and this injury (one that has never happened before) could not have come at WORST time!
Last week of training will be severely hampered if not totally eliminated.
Have any Club Members had lower back strains / sprains ect....
How long were you on the mend and what recovery aids did you use, if any, to speed up the recovery time of this injury.
Thank in advance for any input.
My training has been the best it ever has and i was looking forward to one good final week, before my first International Distance Race Sunday!
I'm no medical professional, but I have learned a few things about my own back over the past year.Hopefully, my next post won't be so long in coming...
First, find out just what HAS happened to your back: It could be anything from a muscle strain (most common) to a damaged/displaced disc (especially if over 40), or a damaged vertebra (rarely). Go to a Sports Medicine MD for a diagnosis, and also be sure to stop by Rehab United for a FREE Injury Assessment.
For what follows, I'm assuming your back hurts all the time, even first thing in the morning. I'll also assume some motions are impossible for you due to back weakness, and other motions cause varying degrees of added pain.
Since muscle strain is a common factor to just about all back injuries, you may be treating that anyway, no matter what else may be wrong, possibly with a combination of physical therapy and muscle relaxants. My own experiences over the past year with a degenerated disc taught me a few things:
1. Don't wait to seek professional opinions! See your Sports MD and Rehab United immediately. Waiting increases the risk of further injury, and needlessly prolongs the pain. I waited over 4 months, hoping to adjust my training to take the load off my back. Dumbest thing I've ever done (well, that depends on who you ask).
2. There are some things that can help temporarily, but may NOT lead to any real recovery: Applying heat/cold, sports massage, very gentle stretching, and NSAIDs (aspirin, ibuprofen, naproxen, etc.). I used these, and the partial improvement I saw is what led me to delay diagnosis and treatment. Not smart! But do use them to help you "get by", but only until you do get your diagnosis.
3. Trying to "train around" a back injury is also of doubtful usefulness. I recommend you stop all running, biking and weight training until you get a diagnosis and training advice, though you may be able to continue swimming in the ocean or bay (avoid pool turns). After my initial injury, I spent months modifying my training, all of which simply made things worse and delayed my eventual recovery.
My current philosophy concerning fitness and competition is simple: I want to be doing this when I'm 80! Any injury or over-training that jeopardizes that goal gets corrected promptly and thoroughly.
My specific injury was a degenerated L5-S1 disc. The disc had been degenerating for a decade, but it became an issue only when my bike training reached new PRs. I was really hammering hard on the hills, and going faster than ever in aero. So when I started getting back pain, I naturally blamed my bike workouts. Turned out my flat-footed running was also a factor, and the two together did a double-whammy on my lowest disc and my back muscles.
The good news is that, once I was properly diagnosed, my recovery literally started with my first physical therapy session. After my therapy ended, I completely overhauled my training to minimize back stresses: First, I became a toe runner (I've got the calves to prove it). Second, I switched from my carbon princess to a TitanFlex (like switching from a hard-tail Harley to a SuperGlide), and I raised my bars 4 inches.
My expectation was that I would eventually compete again, but that I would be much slower than I was before (not that I was ever that fast). The reality has been surprisingly different! I'm now running at speeds I haven't seen in 25 years (though I'm still building my distance back up), and my bike endurance (comfort in the saddle) is better than before (though I'm still building power).
My new expectation is that my race times will become faster than ever! Strange but true: I never would have reached this place if my back had NOT failed. That failure led me to learn more about how my body really works, and to also learn how to use it better.
I also had a huge piece of Pure Luck: About 90% of those with my level of disc degeneration and pain get an immediate spinal fusion. I was a candidate for PT only because my core fitness permitted my back to take tons of punishment without allowing my spine to slip out of alignment. My Sports MD said my successful therapy and return to training will probably postpone my need for spinal fusion by 5 years. I'm hoping for 20.
'Nuf said: Take it easy, get to your Sports MD, and get a FREE Injury Assessment from Rehab United.

Back Pain
Time to 'fess up: I've been having low-back pain since mid-August. It is worst when getting up in the morning, and flares whenever I try to lift anything, including myself. Even picking up a penny on the ground requires that I squat way down. I can't even put on my pants standing up!
I can walk and sit without pain, but that's about it. If I'm careful, I can exercise without pain. But even the slightest mistake guarantees the pain will increase, if not immediately, then soon after the workout ends.
At first, I thought the back pain was due simply to all the additional time I'd been spending cycling in the aero position. But cutting back on my bike time, then zeroing it, did not affect the pain at all.
I talked to a personal trainer, who recommended things not to do, activities and motions to avoid, to help prevent making it worse. It hasn't gotten worse overall, but there are certainly good days and bad days.
I got several massages, and while they felt great and gave me temporary pain relief, they had no lasting effect. But a massage therapist did recommend some changes to my body position when I sleep. That did help reduce, but did not eliminate, the morning discomfort.
I met with a physical therapist, who recommended some simple stretches, mainly for the hamstring, to try to remove stress from the back. No immediate change in the first couple weeks, but I'm sticking with them.
I saw my primary physician to get a referral to my sports medicine doctor, but he said that since I was pain-free for my day-to-day activities, my condition did not rise to the level of clinical significance, so there was no need for immediate treatment. But he did give me a thorough physical to ensure my back pain wasn't a precursor to another condition.
The personal trainer did some research, and uncovered a surprise: Everyone experiences back pain sooner or later in life, and for many people, their back pain lacks a direct cause (such as injury, mis-use or over-use). There isn't all that much known about back pain that lacks a clear and direct cause. One fairly common factor is emotional/life stress, and I do have tons of stress in my life right now.
I should mention that when I was in college I had developed severe back spasms that sometimes kept me from walking upright, and that required medication to relieve. I was scheduled for physical therapy after the spasms subsided, but it turned out not to be necessary. Evidently, just turning off the spasms for a while was all that was needed for me to heal on my own. For the next 25 years I had no significant back pain.
So I know what back spasms are, and I'm certain I don't have them now. The current pain really feels like my back was over-fatigued, but my back hasn't responded to my efforts to eliminate all forms of back fatigue from my daily life.
Could stress be the main issue? The timing is interesting, since the back pain arrived about 2 months after a major increase in the stress present in my life (about 7 months ago).
During this entire year, I had been carefully and steadily increasing my training load (mainly distance and time, not peak effort) in all 3 triathlon sports. The only constant has been my strength training, which I have been doing for about 8 years now.
I have lost about 20 pounds during the past year, which I attribute not only to the higher training load, but also to significant improvements to my eating patterns (I'm not on a "diet"). Thanks to the Holidays, and my currently reduced training levels, 8 pounds of that loss has returned. Not enough to be a strain on my back!
Most importantly, aside from my mystery back pain, I have otherwise been injury-free since starting triathlon: I have tailored my training with the long-view in mind, and have no desire to push myself hard enough to risk injury. But I do want to see steady improvement in all areas, since I know I have lots of room to improve both my speed and endurance.
Fortunately, short runs and long swims still feel good (well, they don't make my back worse), so I do them both in moderation, being careful not to start a run or swim if I'm too fatigued or in pain, and I stop the moment I feel any new pain in my back. And I'm still doing my strength training, modified to avoid loading up my back.
Cycling on the road is out, since I can't hold my back up, and my arms don't handle the extra load very well (hands go numb). Worse is that I can't pedal anywhere near full power, since I need to use my back to get power to the pedals when I'm in the saddle. I'd be more comfortable on the bike if I could sit vertically, but neither my road bike nor my hybrid bike supports that position. All that leaves me with is cycling out of the saddle, which I can't do long enough to last a whole ride. So, I haven't been cycling at all.
That's what I've been telling myself, at least. But the simple truth is there is a way to get lots of biking in, sitting vertically, with plenty of time out of the seat: Spin classes. For some unknown reason, I've been resisting going to class: I think I became spoiled by all the road riding I was doing.
Time for that to change!
