The Shimano M540 is a really popular mid-range SPD pedal. It’s slimmer & lighter than the M520 & significantly cheaper than the top end XT & XTR pedals. The M540 is a mountain bike pedal designed mainly for cross country & trail riding. It’s double sided so it’s really easy to get your foot in & out of & it sheds the mud really well in the winter. The sealed cartridge bearings make the pedals really low maintenance & these pedals are super reliable, as you would expect from Shimano. If you’re looking for a reasonably priced SPD pedal that will last then the M540 is a good option. Features Uses the same design pedal cleat mechanism from the M959 pedal Mud repelling design is suitable for year round use Cr-Mo spindle & low maintenance sealed bearing cartridge axle Cleat tension adjustment Weight: 352 grams per pair
