Hello,
Anyone changed the bearings on a rear Bontrager line comp hub (rapid drive boost type) and know the bearing sizes? Can’t find them anywhere.
I think it’s the freehub ones that need replacing as they feel and sound horrid under load.
Thanks
pretty sure they're 6803 in the freehub (measure them if you're unsure - 26x17x5mm), hub body are 6903 (30x17x7). Consider upgrading to the 108 engagement freehub (by doubling the pawls) at the same time:
you'll need another set of springs too to do that:
I’ve got a new XD driver freehub for this hub that I’ll sell cheap. I switched to Microspline from new.
Simon check the drive side bearing in the rear hub the bearings are poor ive had to change both in my 2 sets
Cheers all
