Build your own Quarq power meter exactly the way you want it. This 170mm gloss carbon crank arm assembly gives you the lightweight, stiff foundation to pair with the Quarq spider and chainrings of your choice, so your fit and your numbers are dialled in from the first pedal stroke.

Highlights

  • 170mm carbon fibre crank arms with a gloss finish
  • 8-bolt direct mount interface for Quarq DZero DUB and DFour DUB power meter spiders
  • SRAM DUB spindle for a stiff, low-maintenance bottom bracket interface
  • Crank arms only - no spider, chainrings or bottom bracket included
  • Lets you choose the exact crank length, spider and ring combination for your build

Carbon arms, your power meter

These are the second-generation (D2) Quarq DUB crank arms - the same proven carbon arms used to construct a Quarq power meter crankset. Because they ship as arms only, you select the matching power meter spider and chainrings separately, which is ideal for upgrades, replacements or a custom drivetrain.

DUB spindle and 8-bolt mount

The integrated SRAM DUB spindle pairs with a SRAM DUB bottom bracket for a stiff, sealed and serviceable interface. The 8-bolt direct mount drive-side spider interface accepts Quarq DZero DUB and DFour DUB spiders only - it is not compatible with SRAM's 3-bolt direct mount.

Fit and compatibility

This assembly is 170mm, one of the most common road crank lengths. To complete the crankset you will need a compatible Quarq DZero DUB or DFour DUB power meter spider, chainrings and a SRAM DUB bottom bracket (all sold separately). Confirm your frame's bottom bracket standard before ordering the DUB bottom bracket.
