Note
* Because the high cable resistance of a frame with internal cable routing
would impair the SIS function, this type of frame should not be used.
* Always be sure to use the HG (Hyperglide)
sprocket set bearing the same group
marks. Never use in combination with a
sprocket bearing a different group mark.
* For the chain, be sure to use only the
Shimano narrow type chain. The wide
type chain cannot be used.
* For any questions regarding methods of
installation, adjustment, maintenance or operation, please contact a
professional bicycle dealer.
