The Shimano Dura-Ace PD-R9100 SPD-SL pedal in the 4mm longer axle (-E1) variant gives competitive road cyclists the performance of Dura-Ace's flagship clipless pedal with an extended spindle that widens stance width — ideal for riders who switch between road and mountain bikes, or those whose biomechanics benefit from a wider Q-factor on the road.

Highlights

• 4mm longer axle: Extends stance width to better match wider-Q-factor MTB setups or suit individual biomechanical needs, reducing knee tracking issues.
• Carbon-composite body: Injection-moulded CFRP body delivers an exceptional stiffness-to-weight ratio, maximising power transfer to the drivetrain.
• Stainless steel wear plate: A stainless steel contact plate protects the carbon body from cleat wear, extending the pedal's service life without adding unnecessary mass.
• Three-bearing platform: Three sealed cartridge bearings per pedal — including a large needle roller bearing — are positioned at both ends of the platform for symmetrical load dispersion and smooth, consistent rotation.
• Extra-wide platform: A 65mm wide platform maximises shoe-to-pedal contact area, improving stability and power transfer efficiency on every pedal stroke.
• Ultra-low stack height: At just 7.1mm, the PD-R9100 sits lower than any other pedal in Shimano's SPD-SL range, putting you closer to the pedal axle for a more direct connection.
• Adjustable release tension: Cleat release tension is adjustable with a 3mm hex key, allowing you to dial in the feel to suit your preference and riding conditions.

Construction & Technology

The PD-R9100 body is built from injection-moulded carbon fibre reinforced polymer (CFRP), the same material found in top-tier road cycling components. The bearing arrangement — two ball bearings and one large needle roller bearing per pedal — is engineered for elongated load distribution across the full width of the platform. The chromoly steel (Cr-Mo) axle provides strength and corrosion resistance, while the stainless steel body plate at the cleat contact point resists the scuffing and wear that would otherwise degrade a bare carbon surface.

Longer Axle Advantage

Riders who train or race across both road and mountain disciplines often find that the narrower stance width of a standard road pedal feels cramped compared to the wider Q-factor of MTB cranks. The -E1 variant's 4mm longer spindle bridges that gap, allowing a more natural leg alignment on the road bike. This longer axle option is equally valuable for riders whose knee tracking or hip anatomy simply demands a wider foot position regardless of their other bikes.

Compatibility & Fit

The PD-R9100 is compatible with all Shimano SPD-SL cleats (SM-SH10, SM-SH11, SM-SH12). The pedals ship with SM-SH12 cleats offering 2 degrees of lateral float. Thread is standard 9/16" right and left hand for use with any road crankset. The -E1 variant adds 4mm to the spindle length compared to the standard PD-R9100.
