Yep, you guys got it as far as I can tell . Yes it's the same crank arms with OEM rings . The arms themselves are called XD(or XD2), when sold as complete unit of Al rings in 46/36/26, then the 600 is added to the name, and called the 300 if the middle ring is steel. It's called the 500 Special Edition if it has a crown logo with Al 48/36/24(steel) rings. The 152mm version uses 50/36/24 Al rings , though the shape of the arms is slightly different than the 160mm+ versions. Kinda odd, but it is what it is.
These OEM rings sold with complete units are not available for sale, which is too bad as I like them better than the "basic" non-pinned ones. It's not the pins and ramps I like so much as the chain clearance is better with no need for added spacers like with the basic rings. They sell high end$$ rings , yes, but they're not these "lesser" OEM's, they are just sold for complete units. My Riv crank came with basic Sugino rings with thin spacers. Some people have said their crank came with the OEM ramped/pinned rings, but they did not say what logo. So they may be selling both the complete OEM units(600) and assembling their own, or if they're all crown logo arms that would possibly mean they are getting both basic and OEM rings and assembling them with the crown logo arms . Or maybe Sugino supplies them with whatever they ask . Or heck, maybe something else altogether as I'm just going by assumptions here !!! -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
