A customer brought in a WH-7800 for me to work on.
Apparently I inspected the rear wheel quite some time ago (before the Nomu Lab days).
It had some lateral runout in one spot.
The front wheel had serious centering issues.
This wheel uses hub-side nipples,
and with rear hubs that's really difficult to adjust,
so fixing the centering would be a real pain.
Fortunately, the front hub is straightforward, so that helped.
It's a 10-speed-only freewheel body that won't accept 9-speed or 11-speed,
but I think this is Shimano's masterpiece wheel,
so please take good care of it.
