I don't know where you got that the Sugino is a 90mm BCD. As I said above, the Sugino will take a 110mm inner ring OR a 74mm inner ring:
<https://lh4.googleusercontent.com/-1QyavWav_4g/TuqGR1HuOwI/AAAAAAAAAiM/QsMBdeiW65k/s1600/conpact-plus.jpg> See? Any 110mm ring you want. Any 74mm ring you want. 74mm goes all the way down to 24. I've never seen the bolt configuration on this crankset when the 74mm bolts are in use. The big ring would have to use single chainring bolts, and the small ring would have a different set of bolts. What other cranksets do an equivalent thing? The RH crankset, the White VBC, and some others. -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
