Broken Rear Shifter, derailleur question
I did search this topic before i posted but found nothing. I have an old stumpjumper with shimano lx components. My gear shifter for the rear gears doesn't work, feels loose and doesn't shift. This bike is just a commuting bike not really for business so i don't care BUT is there any way i can manually shift the rear derailleur to go down 2 or 3 gears without the use of the shifter? because its stuck in 7th and the chain is crossed at times and is starting to skip.
