Mavics, don't those Giant hubs have sealed replaceable bearings?
Edit; Just thought. I think there was an issue with those wheelsets, something to do with the way the rear was laced. My mate had some warranty returns that he re laced and they were fine afterwards……I should know as I'm using them for the 3Peaks.
I've already relaced the pair as yes they were a warranty return pair. The actual build is fine, its just the rear hub has shat itself!
As much as i like the look of those deep section carbon rims, they're both probably quite a bit heavier than an open pro, and significantly more expensive!
open pros it is, the question is, ceramic coated ones or normal!?
