Seeker911 Posted April 18, 2012 Share I need one (or a set) of chainrings bolt for a Shimano Dura Ace 7700 outer ring. The part number is Y-1BM 98010 the size is M8*10.5 Theres a bunch of aftermarket chain ring bolts on the CRC site but I have no idea which of these would be suitable replacement. Does anyone know where I can get such a set or know which replacement set I could buy. Link to comment Share on other sites More sharing options...
Stretch Posted April 18, 2012 Share Really, how often do you replace your chainrings that using a small wierd tool becomes a shlep? i lost three the other day - replaced my chainset and forgot to tighten up! net result was 30km schlep home on granny cross-chain Link to comment Share on other sites More sharing options...
