I got a 26" Huffy Stalker LX(frame is 21")18 spd mtn bike that was given to me. I tried to replace the pedals on the crankarm but the screws is stripped and one pedal is bent pretty good in the crankarm and to me it's beyond fixable.
Can I replace just the crank arm, or do I need to replace the whole crankset?
If the whole set, how do I know what size I need to get for this bike?
Also the gear shift is shot as it will not shift, so I want to have that replace or is there around it to fix the shifts?
Any tips for these questions would be greatly appreciated!
