Jesse Trimblewrote a review of Shimano PD-M540 SPD Pedals on November 7, 2008
I've been riding this pedal for about 2 months. I really like it so far. I switched to this from a Crank Brothers Egg Beater pedal because of the adjustability of the SPD and haven't been disappointed. I rode the egg beater for about 6 months and it seems to have loosened up over that period of time. I'd catch a little bit of air on the MTB and pop out of the pedal upon landing. None of that so far with the SPD.
