Safer and more convenient than using bottles, plus keeps me in the aero position
If you are a triathlete, you want one of these. I know a lot of athletes are always concerned about weight on their bikes, but then they cram 2-3 full water bottles in cages. This system hold the equivalent of two bottles (about 40 ounces), and saves you from having to come out of the aero position to take a sip. Just trim the tube to where you want it (pro tip: trim it long on purpose the first time, you'll thank me later), and you have your hydration right there. The sleeve that goes over the tube has a wire in it that is just stiff enough to bend it down out of the way when not using it, so it's not hitting your face when not in use. The bracket is a very stiff, durable plastic that holds the bottle snug, it's not going anywhere, trust me. The toughest part of this whole deal is getting the bottle out of the bracket - the plastic is that stiff and hard. You'll cuss a bit when removing it, but it's worth the aggravation because you know that thing is secure when it's in place. Comes with all the ties (and they are re-usable) you need to secure the tube in place wherever you want it to be. My wife and I both have one, and we mostly use water in them, but be warned that there are some hard-to-reach corners inside, so if you use a colored drink, it may stain the inside (they make a sleeve/cover for these that works awesome for that). Great product, and they also sell parts and pieces separately so you can replace the tube or bite valve later. For comparison, I'd guess this bite valve and tube deliver slightly more than a camelbak big bite valve per sip, as the tube seems to be just a tad larger than theirs. Liquid does drop back down into the bottle when you're not sipping, so the first sip is always air to get the liquid up to the valve - not an issue for me at all. Considering adding the A2 type bottle/valve from this same company for my fuel during triathlons. Means I'll have two tubes, but won't have to come up off my aero bars for fuel or water in long-course triathlons.

Great water bottle for long rides or TT.
Have been waiting for this water bottle since it's inception and finally needed it. Good set-up, but a little hard to remove from my frame. Like the 40 oz volume provided so don't need to refill. Easy to refill during a ride

I just don't know if I actually like it. There are a couple problems
I used this during ironman Boulder in August. The product does perform as expected. I just don't know if I actually like it. There are a couple problems. 1) I basically had to slow down a TON to get my liquids into the reservoir within the trash zone on the race course and in rushing to squeeze the fluids in, I found that I often squeezed the bottle too fast, which made sticky liquids come out the top and onto my frame. 2) Once the bottle is mounted, it really is not very easy to take off and on my Cervelo p3, it interefered with putting my bike on my hitch mounted bike rack. Basically the bottle is right where one of the rack arms needs to go, so it's kind of a pain. I noticed some people complaning that this isn't good for training. This is the type of thing you put on your bike before a race. Anyone that buys this for use in training is a glutton for punishment. In summary, I can see this working well for some people, but I just feel like in actual race conditions, when the Ironman races are so strict about having to throw your trash out within about 50 yards of the aid station (or get sent to the penalty tent), you end up wasting any aero advantage that you gain from this bottle when you try to refill the bottle. I will probably try a different set-up on my next race. Also just a side-note, the Cervelo P# that I ride only has 1 cage mount on the frame. On a frame with 2 cage mounts, this product might be more worth it. The reason being that you could leave the seat tube cage empty and use it to store the empty bottles after you fill up the aero bottle, thereby eliminating the problem of feeling like you don't have enough time to fill the aero bottle within the trash zone on course.

Excellent product and company
The bottle is sturdy and sleek. I was looking for something that was easy to access but didn't make a mess. They say the bottle between the arms is more aerodynamic, but it invariable makes a mess, and if you have something sticky, it can get nasty on long rides. This keeps things clean while keeping fluids in easier reach than the behind-the-seat water bottles are. Some reviews mention that is difficult to remove, but that also means it won't be moving around on you while riding. Also, I had to contact customer support for some things - they took care of my problem FAST, and shipped some replacement parts the next day with no charge. Great support if you happen to need it. If you're on the fence like I was for awhile, this is a great 40 ounces of fluids that is easily accessible - definitely worth it for the long rides.

Great product for any cyclist
I have owned my Speedfill for a year and a half and absolutely love it. Currently mounted on my 2007 Specialized Transition aluminum frame. Just ordered a seat post kit to mount it to my recently ordered Felt DA4. In spite of losing the "flapper valve" piece of rubber I have very little splashout/leakage and only when completely full and hitting large bumps. The hose is very adjustable and I'm able to set it up where I have to bend my face down 2"-3" to take a drink. As other reviewers have noted, it's a bugger to remove the bottle for cleaning and the fill lid is very close to my (size Small) top tube. If you are a higly competitive time trialist/triathlete you could argue some about added weight as they may only carry 1 20 ounce bottle. Personally on longer rides I don't want to depend on the aid stations or guess at what they have. I have a two bottle mount behind my seat for Cytomax/ carbs& electrolytes and put water in the Speedfill to sip on as I go. I once put drink mix in it, but as mentioned before, it's a bit of a pain to clean and can gum up the tubing. After a race/ride, I take of the lid, pick up the bike and pour out the water. After I get home I wrestle the bottle out of the bracket, give it a good cleaning and cover everything with cling wrap until I'm ready to use it again. PRO's: *40 ounces of fluids available hands free and with eyes on the road *aero design integrates with most bike frames *easy to fill on the fly and no splashing/leaking *quality parts and solid mounting CON's: *hard to remove bottle from bracket (only reason I don't give it a 5 star rating) *a bit labor intensive to clean (but no more than a Camelback or other similar item) *may not fit (easily) on some bike frames (I'm a little nervous about the velcro straps to mount to my new Felt) *fluids can get warm over long rides (it's uninsulated like most standard bottles, but you can get a sock cover for $20) I think the convenience and safety features of this product definitely make it a "must have" even for a non triathlete. Well worth the purchase price.

MISSING/SUBSTITUTED PARTS
When you look at the directions regarding installation, one thinks that the product has been tampered with or parts have been replaced with cheaper substitutes and the price difference pocketed. Completely missing from the package is the seat post bracket and rubber grommet, and the rubber spline and bumper. In addition, the velcro strips have been replaced with cheap zip ties. This may not be much of a problem if your bike has mounting screws on the down tube. However, on many aero/TT/Tri bikes - the assumed target for this product - the only bottle cage screws available are on the seat post tube and not the down tube. Which means you may have just dropped $100 for this hydration system, and have to purchase and ship additional hardware to get this mounted with any semblence of stability. Really not thrilled about ruining the finish on a TT/tri bike, some of which cost as much as a motorcycle, with plastic zip ties. For $100, one would expect a bit more attention to detail. The basic design itself is certainly reasonable, but the missing/substitute parts demonstrate poor execution.

Great product
The product was fairly easy to assemble... working the tube into the sleeve takes a bit of work. Drinking from this is way easier and leads to me being more hydrated by the time I get to the run.. too easy to forget to drink with normal bottles. Definitely want to get the sleeve that goes over it as well, as the water does get warm on long rides in the sun. Taking the bottle out of the mount (and back in) to clean is a bit of a pain -- almost feel like I am going to break it as I have to dramatically bend the plastic to extract the bottle, but no breaks thus far. Fit is good on Cervelo P2, as bottle "fills" the section nicely. Refilling on the go takes a bit of practice. Bottle requires filling from right hand side, so you have to be adept at holding steady single handed with left for a bit as you refill with right, without pedaling.

Improved my gravel biking speed noticeably.
I use the frame mounted bottle for my gravel races. It has been such a difference not to have to take one hand off the bars and chance slipping on some loose gravel. Also I can keep on the drops and maintain speed. My bike is an XL 62 cm frame and there is plenty of room for another bottle on the seat tube. I don't have any issue pulling apart the plastic grips to remove the tank - maybe that is because I have such a large bike? Protip: I cut a typical cheap clothes hanger (bent the ends to eliminate a sharp edge) and used it to beef up the included wire holding up the tube. In summary, works great for races. Might not be worth it for training.

Non soddusfatto
Ho trovato la scatola non sigillata e segni di vite sul sistema di fissaggio della borraccia. Mi é stato venduto un usato al prezzo di un nuovo. Tutto sommato é in buone condizioni quindi visto che ne ho bisogno ora lo tengo, ma ho pagato un usato per un nuovo!

水ならOK
取り付けて使用してみました。他の人が言うような右膝が当たると言うことはありませんでした。 ただ1回1回取り外すのは難しいので水以外を入れては使えないなあと感じました。
