The ROSE OSC (Optimal Stiffness Construction) stem combines low weight and maximum stiffness unlike hardly any other stem, because those are the attributes that ambitious racing cyclists look for. The winglet faceplate ensures optimum distribution of clamping forces as well as a reduction in sheer forces, which increases safety. The first-class workmanship and the stainless steel screws ensure long-term safety.

*A steerer shim adapter (prod. code: 228261901) allows the use of stems originally designed to fit steerer tubes with an outer dimension of 28.6 mm (1 1/8“) on forks with a steerer tube outer dimension of 25.4 mm (1”). The slot of the shim should face to the front to prevent any damages to the steerer tube.
