The Shimano R540 SPD-SL road pedal is Shimano’s entry level road specific pedal. The R540 uses a large 3 bolt pattern cleat similar to the Look road pedals. The large cleat on the R540, & the wide pedal body, gives much more contact between your foot & the pedal than on a standard SPD for better power transfer & enhanced comfort on longer rides. If you are just getting into road cycling, or looking to switch to clipless pedals for the first time, then the Shimano R540 is normally the pedal we will recommend They are easy to use & super reliable so you will get plenty of use out of them. Features Wide pedal platform for enhanced foot-Pedal stability Low maintenance sealed cartridge axle unit The low profile platform with open design allows for easy access & cleat adjustments Easy to clip into & release but with stable fit for maximum power transfer to the pedals Wider cleat & binding mechanism for better shoe/pedal contact than traditional SPD systems
