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:

I’ve got a new XD driver freehub for this hub that I’ll sell cheap. I switched to Microspline from new.
