What's the difference between the MTB clipless systems?
Shimano SPD is the most widely used standard: 2-bolt cleats, a robust mechanism, broad shoe compatibility, and readily available spare parts. Release tension is infinitely adjustable on most models via a screw. Crankbrothers also uses 2-bolt cleats but adds four-sided entry, meaning you find the pedal faster without looking down. The open design also sheds mud exceptionally well. HT Components pairs the 2-bolt interface with a larger contact area, giving a stable, platform-like feel underfoot. Time ATAC runs its own cleat system with plenty of float and strong mud management – a good pick if you want more freedom of movement and a knee-friendly setup. Cleats are included with most pedals.
