2 Pack Ultra-Light Full Carbon Fiber Water Bottle Cage, Bike Water Bottle Holder Brackets for Road & Mountain Bike

The cages would have been okay if someone had packed two of the same finish in the bag.

They do exactly what they are supposed to. One bottle cage weighs about the same as the 4 enclosed screws it seemed. I did not use them but they look to be stainless steel.Are they really carbon fiber? Probably. They look really nice and don't have a plastic-cheap look.I like that there is no brand name on it. It's a water bottle cage, not a sponsor.In my picture, they are holding 28fl oz water bottles from 50Strong.

These cages are ultra-light and feel good. However, the design has a lot of flex in it. As a result, my water bottles pop out really easily even on small bumps. This is mounted under my seat. I have to add extra velcro to hold the bottles in. Bummer.=-=-=-Updated: worst bottle cage ever. Even on small bumps, and even with small (18 oz) bottles, my bottles keep bumping out. Stay away, at least if you are mounting under-seat.

These are very decent carbon cages, especially for the price. They hold my Camelbak Podium bottles securely, although I will say I’m a road cyclist and I don’t encounter the same kinds of bumpy terrain that mountain cyclists do.Installation is very easy and screws are included. I just wish these came in other finishes...I would love gloss black ones.

Es una lástima que uno de los dos productos haya venido tan malo, el otro esta muy bien. Siento que vote mi dinero, porque salí a una competencia de triatlón y no me sirvió para nada.Si pueden hacer algo por mejorar y evitar que pierda mi dinero les agradezco.
