My search for a 172.5 crank is still ongoing. I don't know what it is, but I can feel the difference like night and day between a 170 and a 172.5. Does anyone know if the Suntour Cyclone and the Superbe Pro cranks were interchangeable with the same bb spindle taper? At this point I might even consider a Sugino if it had the same taper and I can't get Suntour. I also need the 130 bolt circle to fit my existing chainrings and the general spirit of the bike which is racy 52/42 and the only chainrings that my particular pedaling style seems to work well with.
