XX1 Eagle Carbon Boost Crankset

• Product Details

  The SRAM XX1 Eagle Carbon Boost Crankset builds around SRAM's DUB spindle, a single spindle diameter that fits the same bottom bracket family across road and mountain builds. Carbon Tuned lay-up shapes the crank arms into a hollow internal structure, cutting weight without giving up stiffness underfoot. A direct mount X-SYNC 2 chainring comes standard, matched to Eagle 12-speed chains and drivetrains.

  What Our Gearhead Experts Are Saying:

  "I stopped stocking three different bottom bracket shells the day I started building around DUB. One spindle diameter fits the DUB family whether the frame's threaded or press-fit, so a rebuild doesn't turn into a parts hunt."
