I received a Racing Zero from a customer.
The original Racing Zero had red rim/spokes/hub, but maybe they thought "it might not sell because of the color," so the next year they released this color variant with black/red/black specs.
The customer wants an inspection and a freewheel body replacement (upgrading to Shimano 11-speed). The photos are from after the work, as you can see.
It's a steel 10-speed freewheel body, but
the bearings seem to be pretty corroded. Since we're replacing it anyway, it doesn't really matter.
The cone locknut bolt was pretty stripped,
but the one in back still had good hex, so with proper tools and careful work, we can manage.
When I removed the freewheel body, there was no bearing seal.
The other side has it properly installed, so it doesn't seem like some deliberate design choice. If this were the work of a fellow professional, I'd be upset, but since it sounds like a friend of the customer's did an overhaul saying "alright, I'll do an overhaul for you!", I don't think anything of it.
I cleaned it up and regreased it, then added a seal on the right side as well.
The ball races
have grooves worn in them perfectly, so replacement isn't necessary—actually, it's better not to replace them.
The freewheel pawl spring was bent, but since the customer won't be using 10-speed hubs anymore, we're not replacing it.
I can't tell if the pawl lost lifting power or if the freewheel body had play, but there were marks on the freewheel body from contact with the ratchet teeth.
The 11-speed freewheel body was supposed to be customer-supplied, but
what was in the box was a cheap steel-shaft freewheel body that only fits Racing 5/7. The friend who did the overhaul said "take this, it'll work," so the customer brought it, but this is a 10-speed freewheel body, not 11-speed. Yet there was a spacer inside to convert it to 11-speed by mounting it on an 11-speed body, so it seems the real story is that this was the old freewheel body removed when a Racing 5 or 7 was upgraded to 11-speed, and it was handed over thinking it would fit. Of course, it was just a misunderstanding, with no bad intent.
So we ended up using a white aluminum freewheel body from our stock.
As for the inspection, the rear wheel had terrible centering and runout issues—it was a real struggle. The front wheel came together quickly since the hub condition and rim runout weren't too bad.
