PD-M9100 - The new M9100 XC pedals improve rider stability with wider edge-to-edge contact areas while improving mud shedding through rounded contact points and off-set bindings. Shimano's Rider-Tuned design offers two axle length options including a new 3mm shorter axle to minimize the Q-factor for XC riders who are running Boost drivetrains. This new shorter axle also matches the Q-factor of Shimano's SPD-SL road pedals, providing a smooth transition for road riders diving into gravel. FEATURES: 55mm axle length Wider edge-to-edge platform Step in and out consistency Offset binding for improved mud shedding 1mm cleat spacer included Weight: 310g (52mm), 314g (55mm) PD-M9120 A wider contact area on the new M9120 trail and enduro pedals improves stability while the expanded rearward shoe-pedal contact area better accommodates the sneaker-style flat outsoles used in enduro and gravity riding.
