I know they're cheapies, but I just picked up a set of Wellgo LU-214 City pedals (for my Trek Navigator) from REI, and one spins very freely, and the other stops after just a few turns. Is this mis-match common? All of the sets at the store were like this. Which is the correct condition? I'm just replacing the original nylon Wellgo pedals that came stock, so I'm not up for a lot of expense at this point. The original pedals seem to be different from each other, but neither spins really freely. I'm going to call the store tomorrow, but I'm interested to see if their response is the same as what I get here.
