Thanks everyone. Patrick, have you found some chainrings better than others on on your Logic crank? Somewhere -- either here on or iBob -- I read that TA's rings might work best. I don't have the 42t ring I need so I figure it can't hurt to get one from Peter White. On the other hand, he indicates that TA's granny rings might not work with the Sugino XD:
*Some triple cranksets have fixed studs to mount the innermost chainring. For example, Sugino sells quite a few triple cranksets with 110mm x 74mm bolt circles. A casual glance at the cranks and TA chainrings in those bolt circles might lead you to think that TA rings will work, but in most cases they don't, because the fixed mounting studs for the inner 74mm bolt circle chainring places the ring too far to the inside for use with TA chainrings.* On Wednesday, August 29, 2018 at 2:02:28 PM UTC-4, Patrick Moore wrote: > > IME, you might well be lucky and have no problem running 10 speeds with > old cranks.
