Speedfil F1 Bicycle Water Bottle, Hands-Free Frame Mounted Hydration System with Refill Port

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.

The bottle function is fine. However difficult to remove and install. You are afraid you may break the holder getting the bottle off. Also , it suggests this bottle holds up to 2 standard bottles. Possibly 2 small bottles.

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.

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.

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.
