Loose Pedal Arm
Moutainbike Magna, Right pedal arm hits bike frame as you pedal, crank appears to be a little loose. How do I adjust the crank or pedal arm? Any advice appreciated or if you know of anything else it could be.
Thanks, John

Hi John,
It sounds like either your crank is loose, or your bottom bracket spindle is the wrong size. Check the following video for crank tightening:
If tightening the crank arm doesn't work it's likely the wrong size bottom bracket. Take it into your local shop for a second opinion and replacement part if necessary. If it's a cartridge bottom bracket, the following video will help with replacement:
I hope you get it fixed and back on the road!
