Hi,
I need to get some flat rubber topped pedals for commuting for my old Stumpjumper since my friend doesn't want the XT SPDs on it at the moment. However, I see that some pedals say 1/2" and some say 9/16". What size spindle are normal MTB SPD pedals so I know which ones to get? I can't get to my bike at the moment to check myself.
Thanks.
