Shimano M540 SPD Pedals
Shimano M520 MTB SPD Pedals are an open design pedal at an economical price. The open binding mechanism is designed to better shed mud. Low maintenance sealed bearing cartridge axle.
I've been mountain biking for about 20+ years and up until a few years ago, I was riding flats. I bought these as my first pair of SPD pedals and they have been flawless. They are extremely durable and require practically zero maintenance. I highly recommend these pedals for someone looking to upgrade from flats and increase their speed and efficiency on the bike.
