Ok, my childhood mountain bike that i have for over a decade has finally become unridable... the grip shifter is broken in a unfixable state from an accident. i can ride it as a ss in 6th gear but id rather make it look cleaner.
my questions are:
1) how do i remove the grip shifter completely?
2) are there ss or fixed rear wheels for mountainbikes? or do i have to built my own?
3) the pedal has a very slight play on it and clicks, how do i open up the pedal and fix the play?
4) any tips and or suggestions?
I can at least answer the first one, I did it on mine. There should be a screw, likely on the underside, that you can take out to allow the gripshift to come apart. I don't remember whether I could take it off with the grips still on or if I had to slide it off the end, but you might as well take everything off. GripShifts come with a little short grip that goes after the shifter, and once the shifter's gone that becomes a little stupid looking, so just go buy a regular set of MTB grips before doing it and just change all that out at once.
The rest is more of the same. Take off the front derailleur, and leave the rear unless you've got a chain tensioner handy that you can install. Remove all cables and stuff like that. It's really just as simple as looking for things to unscrew and unscrewing them.
