My everyday front wheel is a Tiagra hub laced to a Bontrager rim. I Recently put on a different set of wheels for a while. While the wheel was off, I took undid one side of the bearing house on the hub just to see what was was going on in there (had never looked inside my hubs/bearings before. I followed instructions from Zinn's book for accessing the hub.
Fast forward to a few weeks later and I stick the wheel back into my front fork, give it a spin and...major friction! It spins maybe 1 revolution then sticks into place. I tried clamping the QR at a few different tensions but it didn't fix the problem. Also spun the wheel as I was holding the axle ends in my hand and it spun fine.
I checked to make sure there was no brake rub and my other wheel spins fine. I'm guessing it has something to do with the bearings. Any idea how I could have messed them up?
