I have a pair of shimano M636 and another pair of Shimano M545 pedals. They are the red platform clipless pedals, and the lighter aluminum bodied platform clipless setup. Both are in good shape. I'd be more than happy to trade for newer XT non-platform spuds. Make me a reasonable offer that seems reasonable. I'd trade for Selle Italia saddles, 29er tires, clutch derailleurs...
