SRAM RED BB386 crankset
Couldn't load pickup availability
The SRAM RED BB386 crankset is a carbon double crankset for road bikes, with a BB386 bottom bracket. The hollow construction extends to the chainring spider, and the hardware is hidden so the carbon can deliver greater stiffness and lower weight. For smooth performance, the manufacturer recommends X-GlideR chainrings, which are compatible with the Yaw system.
The crank arms are 172.5 mm long. This version comes with 50-34-tooth chainrings. Bottom bracket bearings are not included, so make sure you have them before installation.
