Whats the difference between road and MTB clipless setups? I know its a difference between 2 and 3 bolt systems, but what does that translate to when riding?
Surface area contact (between shoe and pedal) is greater on Road.
Distance between ball of foot and pedal axle is smaller on Road.
And it is not necessarily a difference between two and three bolt pattern - but it is true that two bolt spd has gravitated toward mtb and touring (probably bc of sole tread clearance).
