Polisport’s Bottle Cage Pro is extremely light, 33g (without screws). The clever geometry of the bottle cage allows you to quickly remove the bottle from a variety of different angles. This is a huge benefit, while you are riding, have any time to waste, and you need to focus on the road. The bottle cage is also suitable for small bikes and sloping frames that do not offer much space for a water bottle. Stainless steel screws included. You can also match the new R550 with your bike color.
