I can’t comment on chainline etc. but had these Alpina cranks on my beater Fuji Track for about 6 months now. Paid £99 on sale I think, which with the BB and chainring included was definitely a very good deal, still almost 50% of my whole build budget haha
Quality seems good, BB runs smooth, no heel rub yet, threads all fine when installing. Simple looks with a single logo, kind of remind me of Sugino 75 DD’s which for me is THE crankset for fixed.
