Bike Seat Water Bottle Cage Holder & LED Light - Rear Hydration Triathlon Bottle Cage Holder!

Followed the instructions on the card and had it on in 15 minutes. Couldn't be any lighter without being made out of carbon and costing an extra $100. Like other tri bike behind seat systems I've had, bottles can fall out. Ejected a bottle over a speed bump on first ride but made a couple adjustments and found the right angle for me. All good. Will order a 2nd for road my road bike.

Nice seat cage set up. Still room for small saddle case under. Works well. Usual bottle drops over big sharp bumps. Easy and flexible to install

This was exactly what I needed to add on to the back of my bike and was very easy to attach.

I did not have the difficulties installing it that some described. It took me a few minutes, but it has stayed in place well. In fact, I uninstalled and reinstalled it when I got a new saddle and even with the switch, it is still holding steady.

Save a few bucks and order the one without the light since it didn’t work anyway. Other than that, nice carrier.

I have used a few different behind the seat bottle holders and I appreciate the extra bottle capacity they provide with minimal hit to aerodynamics. What makes this one better than the others is that it allows me to have both my under-seat tool and tube bag and the extra bottle holders at the same time. I have learned to use a couple of elastic bands to help hold the bottles in place on rough roads. The only downside is that you must remember to kick a little higher when mounting and unmounting to avoid snagging on the bottle tops.

All of it

This mount was easy to install and can be expanded with a little creative work. Love it for the price.
