I have a 2014 mavic crossmax 29 pro st front wheel which is 100x15mm axle atm.
Looking to fit it to a boost fork, 15mm axle, so need to go 10mm wider.
Can someone recommend me a good 6 bolt spacer and longer bolt kit, and wheel adaptor wise should I just get the mavic ones?
thanks in advance

I didn’t realised mavic made them. Have you got a link? If they do their own adapters I’d get them, because the spacer kits are a bit fiddly when fitting and removing the wheel. Less of a problem if you remove the wheel infrequently.
