Profile Design RM1 Rear Mount System
Best aerodynamic hydration solution for long-distance triathletes and road cyclists.
This rear-mounted system cleans up your bike's profile by tucking hydration behind the saddle for better aerodynamics. While the included cage offers a rock-solid grip that keeps bottles secure on rough roads, it can be frustratingly tight to access while riding. Fortunately, the sturdy aluminum mount lets you swap in your preferred cages.
