I'm trying to remove some Ritchey clipless pedals to switch over to my new bike. The problem is that the pedals have been on the old bike for 8-9 years, most of which the bike has been in storage. I'm worried they are rusted on, any suggestions as to how to oil them up or something and get them loose? I even tried hammering the end of the wrench to free them up but they are too tight. I'm clueless mechanically and would appreciate any help. THanks!
