Ofmega cranks
 

Hi y'all, just a quick question.

Ofmega Mistral cranks, what taper do they fit (iso/jis)?
I'm guessing ISO, but I want to be sure before fitting 'em.

My crica1980 Ofmega CXs were ISO, as were the Bianchi-branded 1990s Ofmegas with which I replaced them. If your spindle is definitely ISO, you won't hurt anything by test-fitting. If the cranks slide too far down the taper, they are JIS. The converse, attempting to seat a smaller-taper ISO crank onto a JIS spindle, is considerably trickier and riskier, because one has to judge how far the crank is seating and risks splitting the end of the crank by overtorquing the fixing bolt.
