Controltech Triathlon TT Top Tube Storage Rubber Case Box with Strap ATTK, BAG-01, ST1782

easy to install, it's a bit tight, so if you are buying to carry energy gel and other small snacks, works great. highly recommend it.

Used it today for a 100 mile ride. Wanted it to put food/gels or bike supplies in it. Today I put gels in it, I could only squeeze 5 Gu’s in, and I mean squeeze. I can’t imagine trying to put bike supplies in it. Almost seems pointless. Anyway, that was something I would overlook. I got home and removed it to clean my bike and noticed the tail end of the unit had been scratching and rubbing, it’s damaged beyond being able to buff anything out. My bike is a few months old but has been extremely well taken care of. However this product has damaged the surface of my top frame. I haven’t contacted the seller, I can’t see this being enough to need/have to replace my bike but this shouldn’t have happened and now I’m left with the imperfection. I’m not sure if I’ll keep the box or return, should be an easy fix going forward, you can easily put a strip of tape or pad to prevent it. Maybe they should supply something going forward. But for this reason, I wouldn’t recommend buying unless you plan on adding extra padding to the areas that will rub. Seller can contact me if they want photos.

I wanted to use this product to store my snacks for my long distance bike rides, but the sides are so tight that I cannot open the sides to fit food inside the storage rubber case.
