Aushiker, careful how you mount your front tire with the older Son. I rode with hub rotated so the output tabs and the insulated plugs were next to the dropout. When the wheel was tightened down the LHT dropouts pressed into the plugs then pressed into the aluminum body which I assume has the bearings behind it. After a few weeks I noticed a squeaking noise from the front wheel. The dropouts on the previous bike I had the dyno wheel on weren't as wide so it didn't occur to me that it could be a problem. Same on the
crossCheck. Anyway what happened is the bearings appear to have been damaged as the worn groove on the outside appears to have pushed into the bearings and the sound and grittiness didn't go away when the tabs were rotated away from the dropout.
