asked by: a guest any chance this would work as a replacement for my 39B small ring on my Ultegra 6600 Crank
A.
anwered by: canteau This chainring is not designed to be used with 10-speed chains and does not include shift ramps or pins. You might be able to get it to fit on your Shimano Ultegra 6600 cranks but shifting might not be ideal. If you are replacing a worn chainring the Shimano 6600 39t chainring is available here: http://www.treefortbikes.com/product/333222348036/324/Shimano-Ultegra-FC-6600.html
