Hope's original aluminium crankset, forged and CNC-machined in Barnoldswick, with a stiff 30mm axle and a spline mount that takes a spiderless chainring or a spider. This listing includes the limited-edition Gunsmoke finish alongside Purple and Red.

Highlights

  • Forged and CNC-machined 7075 series aluminium arms
  • Unique expanding spline/arm interface
  • Spline mount for a chainring or spider
  • 30mm oversized axle, 68/73mm length
  • Limited-edition Gunsmoke finish available

Built for hard riding

Forged then machined 7075 arms give Hope's typical strength-to-weight balance, and the oversized 30mm axle keeps the whole crank stiff under power. Hope made axle options to suit most bikes from XC through DH and fat bikes; this is the 68/73mm version.

Chainring choice

With no spider fitted, you can run a Hope spiderless chainring direct on the spline, or add a Hope spider if you prefer a bolt-on ring.
