The XPro and Xpresso Cleats were designed for the Time XPro and Xpresso road pedal program. They allow for angular and lateral freedom to accommodate the natural movements of your legs and joints. You can also adjust the Q-factor by changing the shoe plates to optimize performance in three areas: safety, ergonomics, and performance. The bi-material construction provides greater durability when walking with the cleats. These cleats are the standard cleats included with all XPro and Xpresso pedals.
