hello, i have a project i need advice on, i know very little of how this works.
I have an early 90s trek antelope 800 with 3 speed front ( i just replaced with shimano deore lx m570 rapidfire) and 6 speed rear with rear derailer shimano rd m250.
Im trying to replace the right shifter and components relatively cheaply this will be an ebay build. I would like another rapidfire style shifter , no gripshifts.
I dont know how this works im having trouble finding them, do i just get a 7 speed shifter and set the screws and will that work with no problems, or do i have to change the rear gears? If so; Do i go 7 speed or 9 , ive heard rumours the 9 is more work to fit ?
OR... can i get a better rear derailer that will work in conjunction with a new shifter without changing the rear gears?
Sorry if this is unclear, im new to this (first geared bike!!!!
but i would greatly appreciate any input .If it helps i just intend to buy the parts put them on adjust them moderately and then have it set up at the bike shop
THANKS FOR YOUR HELP IN ADVANCE
