"Inspired by the flagship DURA-ACE system, the new ULTEGRA PD-R8200 brings SHIMANO's next-generation SPD-SLR platform to dedicated racers and performance-focused riders. With a low stack height, improved stability, and easier engagement, the PD-R8200 delivers efficient power transfer and race-ready performance. Available in standard (52 mm) or 4 mm longer axle models.

The new SPD-SLR platform lowers the shoe-to-pedal interface for more direct power transfer and greater pedaling efficiency. The expanded pedal contact surface improves stability during hard accelerations and sustained effort. The refined pedal design and wider cleat catch make clipping in more intuitive. The carbon fiber-reinforced pedal body and proven Shimano engineering deliver lasting performance for racing and everyday riding

The pedals come with CL-SL110 Yellow SPD-SLR cleats that feature a moderate +/- 3 degrees of float. Additional cleats are available with different float and adjustment ranges." - Shimano
