Hi guys,

I have Shimano A530s, which use the SPD 2 bolt system.
I am simply wondering if all MTB shoes use 2 bolt systems, and therefore are compatible with my cleats/pedals.
I am only asking as there are many different systems for road bike pedals, and my cleats do not work with all road shoes (3 bolt systems, special brands, etc). And I am wondering if there are also different cleat systems for MTB shoes/pedals.

Thanks.
