The problem is most bike shops don't deal in these parts, it's why I am buying from ebay/china.

I know it's a pretty easy thing so don't need to take it to a bike shop....

All's I need to know is if anyone who has dealt with this sort of thing before, would the suggested crank (2nd link) be OK for this??? Or do I need to try and squeeze that BB CUP (one with two pin holes) in a little bit????
