Hello all and happy new year!!

I'm thinking of upgraded the wheelset on my Stumpy SS 29er to the Mavic Crossmax ST wheelset but not sure if I technically can.

I currently have a 9mm on the front axel and a 10mm on the rear axel. The ST wheelset can do a 9mm on the front, but shows a 12mm on the rear axel.

Will this be an issue?

Thanks in advance!

EDIT: It's the alum frame with the EBB.
