The 2-hole system is commonly known as the SPD system (SPD = Shimano ® Pedaling Dynamics). The 2-hole system can be used for all types of riding, including road cycling, mountain biking, touring and commuting. When paired with some shoes, the recessed cleat design allows easier walking. Most off-road racing, where a mud-shedding cleat design offers an advantage, is where a small two-hole cleat is popular.  There is a road specific version known as “SPD-SL” (3-hole bolt pattern).

The 3-hole system is also known as the Look-style system (for the pioneering manufacturer/brand, Look Cycles). The 3-hole system is most often used for road cycling because it offers a stable platform for energy transfer while riding. The soles of many performance oriented shoes are often made more for riding than walking with stiff soles and little tread.  The larger cleat design incorporates a three-fastener connection, which is much more secure connection than with two fasteners like the ones found with the 2-hole type. Popular brand names of 3-hole bicycle cleats are Look ®, Shimano SL, Time ® Road and others.  Due to the popularity of Shimano cleats, we refer to these wedges as Look/Shimano.

The 4-hole system is associated with the Speedplay® pedal/brand.  Speedplay design has the clasping mechanism on the cleat, rather than on the pedal, like with SPD and Look systems.  In this system, the shoes are made more for riding than walking.  The system with a four-fastener connection, generally offers more adjustability options in the foot/pedal connection, often making it a favorite of bike fitters.  We offer these in both the Walkable™ style (shown below) and regular road cleat style.
