SPD Pedals – Shimano DX SPD
SPD is the term commonly used to refer to clip-in style mountain bike pedals. The correct name for clip-in style pedals is actually “Clipless” pedals, however many people incorrectly call them “clip-in” pedals because that’s how they work, a metal cleat fitted to the persons shoe clips-in to the pedal.
The Shimano DX SPD model differs from the other SPD pedals, as they are designed for more technical tracks so it has a “cage” that surrounds the pedal clip-in mechanism. This cage does two things: The main one is to provide a bigger pedal surface area if the rider has to clip-out then place their foot back on the pedal as quickly as possible. This can happen on rough terrain where it’s difficult to locate the foot exactly correctly back on the pedal. The cage also gives the pedal retention mechanism and some protection from rocks. Hitting the pedal on a large rock on the track while pedalling is called a “pedal strike”. This can damage the mechanism.
For interest, SPD is an acronym for the Shimano brand, and stands for Shimano Pedalling Dynamics.
Please note: To use SPD pedals, you must have your own mountain bike type shoes with a compatible cleat fitted.
