Build your own dream Eagle drivetrain from the ground up with SRAM's lightest, stiffest carbon mountain bike crank arms. This XX1 Eagle DUB crank arm assembly gives you the bare CARBON TUNED arms and DUB spindle in a 175 mm length, ready to pair with the spider, chainring and power meter of your choice.

Highlights

  • 175 mm crank length for added leverage, favoured by taller riders and climbers
  • CARBON TUNED arms tuned for maximum stiffness and efficient power transfer
  • SRAM DUB 29 mm spindle for a simple, durable bottom bracket interface
  • 8-Bolt direct mount interface for 8-bolt chainrings and Quarq power meter spiders
  • Grey finish to match XX1 Eagle componentry

Crank arms only, your build your way

This is the crank arm assembly in isolation. The bottom bracket, spider and chainrings are not included, so you can spec exactly the chainline, ring size and power meter your bike needs. SRAM Torx T20 mounting bolts are supplied for the 8-bolt interface.

DUB and 8-Bolt explained

The DUB spindle is a 29 mm SRAM standard that runs on a matching SRAM DUB bottom bracket (sold separately) to suit your frame's shell. The 8-Bolt direct mount interface accepts SRAM 8-bolt chainrings and the Quarq DZero XX1 Eagle power meter spider for a clean, quiet, low-maintenance drive side.

Compatibility and fit

Suits SRAM Eagle 12-speed drivetrains. Requires a SRAM DUB bottom bracket matched to your frame and an 8-bolt chainring or 8-bolt spider, plus a chainring to complete the crankset. Not compatible with SRAM 3-bolt direct mount chainrings. Pedal thread is 9/16 inch.
