Question for you pathy guys out there... How warm are your rear hubs after being on the highway for a while? Today I actually felt heat coming from the back tire, when I checked it out, it appears to be coming from the hubs. Not too hot to touch, but definitely warm.
Budrbean talked about changing his bearings a while ago, and we discovered that the bearings are in hub assemblies on both front and rear. Easy to replace, but expensive.
Ever since I got my REV02s, and with how quiet they are, I thought I might be hearing some bearing noise from the rear, but dismissed it.
