E Notes
e In order to maintain smooth shifting performance of the HG
(Hyper-Glide) sprocket, do not use a B-group and C-group
sprocket combination. (Use each group as a 7-piece set.)
e For freehubs (FH-M732/FH-MT62/FH-M452) for the HG
sprocket, former UG sprockets (CS-6400/CS-1000) can be
used, but do not combine the HG sprocket and UG sprocket.
