The S-900 caliper is Flat Mount Only, and 160mm or 140mm centerline x rotors are recommended. Rotors are not included.
For Aero disciplines, hydraulic disc brakes can reveal a whole new world of speed savings.
Less time slowing down means more time going fast. Better brakes mean faster splits, thanks to confidence inspiring brake performance
Disc brakes allow optimization of the most critical frontal area of the bike frame - the fork crown/headtube/downtube interface - for aerodynamics
Hydraulic road disc brakes (HRD) also require less hand effort to actuate and provide shorter braking distances and easier changes between wheelsets.
The S-900 HydroT concept is SRAMS first Hydraulic Road Disc Brake Platform for TT and Tri bikes. Highlights include
