Anybody know what spindle length of shimano un55 bb I need to buy to get proper chainline on italian threaded bb shell? Miche primato crankset. Thanks
That depends on the crankset you are planning to use.
It's a trap.
You should use an ISO taper bb, not a JIS Shimano bb.
Campag make one in 110mm, Token and Tifosi brand one in 111, both are fine for a normal track hub.
