I was thinking Sugino XD which is 9 sp compatible. The chainrings are pinned, at least in the photo. http://www.lickbike.com/productpage.aspx?PART_NUM_SUB='0043-70'C-40 said:If a crank is 9/10 speed compatible, then it will work with Campy. All modern 10 speed drivetrains use the same 5.9mm chain width.
I was afraid of that. I almost never use my big ring on the triple. I 48T would be a much better alternative for my style, slow that is.C-40 said:The actual chainring tooth spacing between 9, 10 and 11 speed is nearly the same. The big difference is in the shifting ramps, changed to match the various chain widths.
Campy made no change to their chainring in 2007 when they made the chain 5.9mm wide instead of 6.1mm.
The only way to tell for sure if a crankset will work is to try it.
Of course Campy cogs spacing is different (4.15mm for 10 speed and 3.8mm for 11 speed, compared to Shimano/SRAM 10 at 3.95mm).
