A customer dropped off the front and rear wheels of an Aiolos XXX4 for service.


They wanted the front and rear wheels checked for trueness.
The front wheel had a slight centering issue,
and both wheels had a bit of runout.
These are Bontrager wheels, but this is a quick-release, rim brake rear wheel from the period when Shimano components shifted from 10-speed to 11-speed.
When swapping out the DT hub's Shimano 10-speed freebody for an 11-speed version,
the right side dropout end becomes longer,
so after upgrading to 11-speed the rim shifts toward the non-freewheel side—
and in a pretty noticeable way I couldn't ignore—
but back then Trek actually issued a statement saying
"don't re-center the wheel,"
and I don't know the reason, but I thought to myself,
well, that's the level of wheel knowledge this manufacturer has,
but interestingly, this newer disc brake rear wheel didn't have any centering issues at all.

Both wheels are 24-hole with equal spoke counts on each side.
The front wheel has a radial spoke pattern on one side, equivalent to a 0-4 (zero-four) pattern,
and the rear wheel has matched spoke counts on both sides, equivalent to a 4-4 (four-four) pattern.


After inspection, I trued the rear wheel on the non-freewheel side per the customer's request.
