I am fixing up a cheap bike to ride, and this is the first time I have tried doing my own repairs. I
could really use some advice about my drivetrain.
Originally the bike had a Shimano SIS gripshift, but the right one wasn't working (jammed) so as a
temporary measure I replaced it with a regular shifter, with a lever. Only problem, I have 6 rear
sprockets and my new shifter in indexed for 7. Shifting is not great, and I'm not so optimistic that
I could improve it much by adjusting the derailer. Maybe this isn't the case?
My question is: Can I use any Shimano SIS shifter indexed for 6 sprockets, and have it be compatible
with my derailer/freewheel? In other words, can I just buy a new (grip)shifter and have some
confidence that it will work fine on my bike? How much should I expect to pay for a shifter?
Or am I better off replacing the derailer and/or sprockets at the same time? I have no reason to
believe the derailer needs replacing, but the sprockets look a little worn. I would ask at the bike
shop but I think I already know what they'll say ;-)
I think eventually I will want to upgrade the whole drivetrain, but if I could I would prefer to get
the one I have now working at optimum and save the money.
Thanks,
Adam
