Shimano M540 pedals review
What does your extra tenner get you over the Shimano M520s? Well, the M540s are a wee bit lighter and everything just feels a bit better quality out the box.
There are also no spanner-flats on the chromoly spindles so they tighten onto the crank with an Allen key out back, looking neater as a result. Apart from that it’s more-or-less the same pedal, the same gappy mud-friendly design, the same Shimano float-and-release feel.
