Sporty design with maximum grip. The same innovative technology as the glossy version, but executed in a modern matte black finish. The Double Fit weighs only 49 grams, making it a lightweight addition to your sports bike. The holder is easy to mount and keeps both water bottles and PET bottles vibration-free in place. The Simson Double Fit bottle holder effortlessly holds all traditional water bottles during your bike ride, and the patented bottle neck opening also makes the Double Fit suitable for safely and cleverly transporting PET bottles. With the unique click system, you can easily release the bottle from the holder to quickly drink while cycling. The Double Fit is lightweight (49g) and very suitable for sporty cyclists. Mount the Double Fit to your bike using an Allen key and the included Allen bolts.
