This is a relatively expensive axle, BUT well made, light AND is compatible with Hexlox security inserts. Recommended if you have nice wheels.

Can I use this with a Raleigh Mustang comp ebike
06 Jul 2020
I snapped my thru axle and now I'm really struggling to find a 1 that fits. I've emailed Raleigh but what with the virus and everything it's taking a long time for them to reply. The size is m12-174-p1.5 I'm hoping that the 2 mm short won't cause a problem for my set up
We cannot recommend this product for you as you should never use an Axle that is too short for your bike, please refer to the Robert Axle Project fitting guide for further information as to Axle sizing:

Dear Sir or Madam
I have an Enigma Excel road frame with Campy group set and Bora wheels. The supplied axle is a Shimano M12xP1.5, length 171mm. Would the above Robert Axle Project axle be a suitable alternative or would you recommend something else?
Many thanks
Yes, that would work.

Thanks - 22/07/19
