для трейла - 530е, для кросс-кантри и покатушек - 520/540е

Though the new pedals weren’t designed to specifically offer more platform to stand on, if you’ve got very flexible soled riding shoes you might feel a bit less shoe curl using the M530s. Going back to a conventional sized SPD pedal you immediately sense the pedal is harder to locate on entry and more prone to roll.
If you’re considering an upgrade or first time buying SPD pedals try the ‘Trail’ M530 in preference to the old M520.
