Original Design Didn't fit my wife's bikes so I Changed the spread and Diameters & added a little more material in the crotch to beef it up a little, but this design snaps on to the profile water bottle perfect you don't even need the strap (but safety first don't want to loose this on a big bump LOL)

Quote from org Post "Mounts a Profile Design Aqualite aero bottle to Profile Design T2+ DL aluminum aerobars. This setup allows you to drink on a ride without reaching for a separate bottle down below. It keeps you focused on the road and drinking more often during the bike leg of a triathlon."
*NOTE- different sizes** Also if your looking for a special spread and diameter let me Know I'll post for you just need center to center distance and bar diameter.
Thanks MatthewGTaylor for posting the the original design much appreciated!
PLA or ABS for great it's light and strong.
