Sram RED BB30 eTap CWR8386004

SRAM RED BB30 eTap Crankset Improved for the unveiling of the highly anticipated eTap system, the SRAM RED BB30 eTap Crankset has been redesigned to work seamlessly with SRAM's wireless shifting system. This crankset comes in several arm length options, ranging from 165 millimetres to 177.5 millimetres. Three chainring ratios are also available; 50/34, 52/36 and 53/39, so you can pick the most suitable gearing based on the terrain. With carbon arms and aluminium chainrings, this crankset combines lightweight performance with durable and reliable shifting. The crankset features a completely hollow construction all the way to the spider. Its hidden bolt pattern makes better use of carbon fibre to further improve stiffness and shed weight. The BB30 bottom bracket provides serious weight savings and a narrow Q-factor, more ankle clearance, greater bearing durability and stronger crank construction.
