My purchase decision was on this very pleasing SPD pedals of Shimano as they complement my mountain bike in perfect Shimano XT equipment. Shimano with intuitive manual assembly with a matching Allen key is anyway typical problems. My impression after the first exit: the entry and exit is just a tad bit easier than that has previously worked well with the previous model PDM-520. With 343 grams of the clipless pedals are also a little easier are also twice as expensive. Good that I have received from Amazon at a great price.
