Did your bike come without bottle cage mounts, or do you just get sick of having to reach all the way down to the down tube to hydrate? Profile Design has the answer to all of your problems. The Rear Mount bottle cage system mounts directly to your seat rails and carries not one, but two standard water bottles. Not only that, but the bottles will be conveniently located right behind your butt—a much shorter reach than standard bottle cage mounts. Along with carrying your bottles, this bracket conveniently holds two CO2 cartridges for roadside repairs.

The Profile Design Rear Mount bottle cage comes in one size. It's available in black.

Here's what others have to say...

Hi, is this mount compatible with a 2015 Cervelo P2, with a ISM Adamo Road Saddle? Tks. Dan

HI Dan

This just attaches to the saddle rails, so it will work just fine.


Mounting screws not long enough

  • Familiarity:I've used it once or twice and have initial impressions

The bolts that come with the system intended to mount to the bottom of the saddle are not long enough! Luckily I had longer bolts with same diameter from some old profile design aero bars. After using longer bolts I was able to use the system. If you purchase this item, the manufacturers bolts may not fit your saddle rails.
