Frustratingly Shimano made the inner diameter bigger for m570 to m572, these need cutting to fit and I can't bring myself to do it! I do love it when they make things easy!!!
Hi,
Looking for a 32t middle chainring to complete my 1999 Kona Pahoehoe build. These are 104bcd but the inner diameter is narrower than any other 104bcd chainring and a really faff to find!
Any help much appreciated.
Hi,
Does anyone have any NOS chainrings for m570 m571 m572 m670 m671 etc chainsets please? (Especially the middle one!)
It's for my 1999 Kona Pahoehoe, otherwise perfect.
