Swaps your bike's thru-axle for a Robert Axle Project trainer axle, so a thru-axle bike can mount on a wheel-on resistance trainer. This M12x1.75 axle is sold as separate fixed-length axles rather than one adjustable shaft - choose the length Robert Axle Project or the Tune workshop has confirmed for your bike.

Highlights

  • M12x1.75 thread
  • True lengths from 159mm to 192mm, no spacers needed
  • 7075 aluminium shaft, hard-anodised
  • Fits with a standard 5mm hex wrench
  • Usable on or off the trainer - remove the drive-side end to ride outside

Compatibility & fit

Fits 12mm thru-axle bikes using an M12x1.75 thread. Thru-axle length is not the same as hub spacing, and axle ends extend roughly 15mm past the frame each side - measure your trainer at its widest setting before ordering. Confirm your bike's exact axle length with Robert Axle Project's online Axle Finder, or bring the bike to the Tune workshop and we'll measure the existing axle and fit the replacement.
