This Red C2 crankset uses SRAM Exogram hollow carbon arms and spider construction, with a hidden-bolt layout and machined-alloy X-GlideR chainrings. The ring design is matched to SRAM’s Yaw front-shifting system.
The black selection is GXP with 172.5mm arms and 52/36T gearing for a 2×11 road drivetrain. Confirm the required GXP bottom bracket, chain and front derailleur. Other spindle options listed for the family are separate products, and the 53/39T weight is not this gearing’s measurement.
