At the moment got standard qr wheels. So what will fit in my forks? Obviously 9mm qr but what about the other sizes? Ok so not any bolt throughs. Oh and on the back what will fit and what’s the difference between 135 and 142,.apart from 7mm. Posted 4 years ago rickonSubscriber You’ll need 135 qr for the rear, front depends on your fork and hub. Generally you’ll need qr, but you may be able to get 9mm adapters for your hub and use a 9mm bolt through. Posted 4 years ago schmikenSubscriber As above, you’ll need 100mm wide 9mm QR front wheel (it is possible to get a bolt through version), and a 135mm wide 10mm QR rear (again, possible to get bolt through type). http://superstar.tibolts.co.uk/product_info.php?cPath=40&products_id=797 Posted 4 years ago Viewing 3 posts - 1 through 3 (of 3 total) The topic ‘axle confusion’ is closed to new replies.
