Ride comfort is greatly increased.DFS offers a variety of different professional road bicycle carbon fiber rims.This disc brake specific high-performance rim technology is your ultimate partner from start to finish. Featuring a 30mm-31mm ultra-wide aero-rounded profile (23.5mm-24mm internal width) , it perfectly pairs with 35–50mm tires to create an optimized tire-to-rim interface—delivering superior cornering grip, exceptional crosswind stability, and significantly reduced rolling resistance.

By eliminating the rim brake track, we've unlocked a new realm of weight savings. Without the need to withstand braking forces, the rim structure is radically lighter than equivalent rim-brake models, while retaining exceptional strength. Every gram of material is now laser-focused on its primary duties: supporting the tire and managing spoke tension. The result? A rim that is strong, featherlight, and relentlessly fast.
