I might be swapping some wheels around and wondered whether I can convert a wheelset with a 20mm bolt through front and a 10mm bolt through 135mm rear to standard QR on both?
Thanks in advance.

you need to know what hubs you have EVI, Pro 2 etc then you just buy the appropate conversion kit.

Just standard Pro 2s.
I will have a look
Thanks

Yes you can.

Front will be new end caps,

Rear will be a new axle and end caps.

If you are wanting to get rid of the 10mm through axle and end caps i would be interested in swapping them for standard QR bits. Email is in profile if you are interested.

Probably will be but away at the moment but will contact you when I get back. Upgrading wheels on a Blood and swapping them on to another less burly bike.
Thanks
