Hope's RX crankset brought its mountain bike know-how to drop-bar off-road riding. It was Hope's first two-piece hollow crank, designed for a balance of stiffness and low weight while being tested to the same standards as its MTB cranks.

Highlights

  • Two-piece hollow construction, fully CNC-machined
  • 30mm aluminium axle
  • Tested to Hope MTB crank standards
  • Direct-mount chainrings keep weight low
  • Designed, tested and made in Barnoldswick, UK

How it is made

Each arm is CNC-machined in two pieces so unwanted material can be removed from the middle, bonded with a structural adhesive injected under controlled parameters, then finish-machined to its final shape.

Chainring options

The RX is optimised for a single ring and takes Hope direct-mount narrow-wide chainrings (38, 40, 42 and 44T). A Hope five-arm 110 BCD spider, sold separately, also allows double chainrings.
