The Shimano DURA-ACE PD-R9300E1 are one-sided SPD-SLR pedals for road bikes, featuring a sealed mechanism and adjustable release tension.
SPD-SLR is Shimano's road pedal system with a distinctive cleat-to-pedal connection. Compared with SPD-SL, shoe height above the pedal is reduced by 2.3 mm, bringing the foot closer to the pedal axle for a more stable platform and more efficient power transfer. The wider engagement area makes clipping in easier. SPD-SLR pedals and cleats are not compatible with the previous SPD-SL system.
