SRAM is finally making their own direct mount rim brake. Better late than never.
It is compatible with all SRAM mechanical brake levers from the top of the line Red eTap to the entry-level Apex group. The S-900 direct mount brake features an offset synchronizer screw to adjust for simultaneous engagement of the pads while pulling double duty to minimize splay force so energy goes into the caliper instead of flexing the frame/fork. All that translates to better modulation and brake power because nobody likes spongy brakes.
Weighing at a claimed 326 grams per set, the S-900 direct mount caliper is also designed with the latest trend of wider wheels/tires in mind with 28mm of clearance and it also comes stock with SwissStop FlashPro pads. It is, however, compatible only with fork and seat stay mounts.
