Speedfil A2 Bicycle Water Bottle, Between the Arms Hands-Free Hydration System with Refill Port

Excellent kit for my bike with many ways to mount (bought the bar mount as well). Also makes it easy to tape CO2 cartridges and gel packs to it. Love the Garmin clip on (required slight modification to work). Does not seem to work with other bottles very well, must use the one that it comes with. I was oping to use a larger one but did not have any luck. Refilling works quite well. The velcro holds the bottle in solid. Use a large rubber band to hold the straw in perfect position while riding.

The elbow joint/gasket that attaches to the bottle does not fit snugly and therefore is free to rotate around. It even came out on my during my ride. I ended up jury rigging it with electrical tape to keep it still and changing the straw tubing to a more flexible tube so I could lay it down when I wasn't drinking. Nice idea but crappy straw attachment system. I'll be going with the Xlab Torpedo 400 for my race instead of this garbage.

Works great on the tri bike, no trouble filling while on the bike for my most recent 70.3. Easy to clean as well.

Great drink solution for the Triathlete. Independent testing has also shown that the most aerodynamic way to carry hydration is between the aero arms in the aero bars. I gave 4 out of 5 stars because this product, though great, is not quite perfect. It does take out the equation of having to have a custom shaped bottle, and it does well in crosswinds, but the straw mechanism will not let you completely deplete the fluids inside of the bottle without adjustment.

It fits well/easy to access BUT....once you take one sip, the straw isn’t submerged in the water. Seems to only work well when it its totally full. Not efficient/you have the twist the straw in weird ways to get water. Not easy while riding.

It's okay. Does a better job than some other aero bottles at keeping fluid inside but it still leaks some. It's also heavy by itself even without fluid in it. More convenient than most other refillable alternatives being interchangeable with the collection of bottles we all have. Like i said, it leas a little but not as much as the others i've had.

Had bought one of these on E-bay in the spring and after 1 or 2 uses the thin gasket sealing ring in the cap broke rendering it useless as it constantly leaked. Rolled the dice on this one as I have a Full Ironman coming up and needed the ease of drinking on the fly. Very happy to see that the new one is much improved with the sealing area molded in a larger profile and in a more durable plastic. Mounts perfectly between the Aero bars for easy hydration.

Leaks! The elbow joint leaks, the straw leaks, the bite valve leaks. I had one for awhile and it leaked so badly it corroded my headset bearing. Bought a new setup and switched the mounting direction, and the new one leaks just as badly. I lost so much fluid on my ride and was a sticky mess. I have called and emailed and Facebook messaged this company asking for replacement parts or assistance and have received nothing at all in response. Poor customer service and a cheap product that I really wished worked. Love the way it’s mounted and the way it fills, just wish it didn’t leak. Ridiculous that they don’t even care to contact you back. Super angry!
