BB - has Cr-Mo CV-170 84 -C ? Is that a year or just parts number ?

does any one know who's make it is and what year it is from ?

cheers mate for the pic  ;)

do the cups look right for a tioga set ? the rest seem to match or so, but the inside cup edge is not the same - and it still doesn't explain why one of the cups is out by a mill all around ?

cheers B  ;)

It's one of these B. Got one here all exactly the same except my axle is stamped 83-C & has a little Tange logo (could be a year thing) 8)
Tange also released it in their own branded packaging. Got another CV-170 Axle from a CK-170DX BB Set with no logo or date stamp.
Hope that helps :)

Is it definitely the cup? Did you try them both in the same side?
I'd maybe make a metal shim - Coke can or some of that foil ribbon used for Pro Class Rims ;)
