These plates work for both older Sidi's with the recessed adapter plate system and Sidi shoes with the Millennium sole. They allow two-bolt SPD cleats to be installed on a Sidi road shoe with a three-hole drilling. Commonly used to attach SPD cleats to a three-hole road shoe to use in a spinning class on a SPD spinning bike.
SIDI SPD® adaptor plates do not match the curvature of the Millennium 3® sole, and SIDI cannot be responsible for their use with this sole. If you prefer to use a mountain bike pedal on your road bike and you have a Millenium 3 sole, Sidi recommend you purchase a MTB shoe.
Does not include SPD cleats - sold separately
