Sugino’s OX601D is the less expensive version of the company’s OX801D compact-plus crankset.  The combination 110mm/74mm BCD allows small rings as low as 24t and specially-matched big rings as large as 50t (or as small as 42t).  Q-factor is 145mm, and the ramped-and-pinned chainrings are compatible with 9/10s Shimano and 10s SRAM chains (and worked fine with my 10s Campagnolo drivetrain).

Stay tuned…
