Super light all carbon fiber water cup holder for mountain road bicycle

Specification:
Material: Carbon fiber
Opening diameter: 71mm
The carbon fiber bottle cage is very flexible and can use water bottles with a diameter of 70-74mm
Holds regular water and sports drink bottles for peace of mind while you ride!
If you put a water bottle with a diameter of more than 71mm, it will feel a little tight. Don't mistake it for small.
It should be tightened while riding to prevent it from falling off. Especially the weight of the bottle filled with water will increase. If it is not clamped, it will fall off easily!
