The new Shimano S-PHYRE RC910 pushes the boundaries of Shimano top-of-the-line road shoe performance. Featuring a new DYNALAST 2.0 fit, dual BOA® Li2 closure system, a new carbon heel, and an SPD-SLR interface, this shoe is designed to deliver precision, stability, and power transfer at the highest level.

Shimano S-PHYRE RC910 SPD-SLR white road cycling shoes

The white Shimano S-PHYRE RC910 shoes represent the new generation of Shimano high-end road cycling shoes. Succeeding the RC903, they have been completely redesigned to improve comfort, foot support, and pedaling efficiency to the highest level.

Designed for the most demanding competitors and cyclists, the RC910 combines the new SHIMANO DYNALAST 2.0 fit, a repositioned BOA® Li2 dual closure system, a new carbon heel and the new SPD-SLR interface.

A new generation of S-PHYRE

New SHIMANO DYNALAST 2.0 fit

The RC910 adopts the new SHIMANO DYNALAST 2.0 . Shimano has notably reworked the front part of the shoe to offer more space at the toe area.

This new shape allows the toes to spread more naturally inside the shoe, with the aim of improving balance, stability and comfort , especially during long outings and prolonged efforts.

Precise support without excessive compression

The new DYNALAST 2.0 last also focuses on instep support. The goal is to achieve a sufficiently precise fit to effectively support the foot without exerting excessive pressure that could compromise comfort or blood circulation.

High-precision adjustment and support

Double BOA® Li2 repositioned

The RC910s use a dual BOA® Li2 system allowing for precise micro-adjustments of the tightness.

Shimano has also changed the positioning of the BOA dials compared to the RC903 in order to improve the distribution of tightening, support and comfort during exertion.

New lowered carbon heel

The new S-PHYRE RC910 receives a redesigned and lower carbon heel compared to the RC903.

This development aims to improve comfort around the heel and reduce potential pressure points, while maintaining the level of stability needed for accelerations, sprints and high-intensity efforts.

Foot stability and control

The heel structure helps limit unwanted foot movement within the shoe. This provides the cyclist with precise support as power increases, without sacrificing the comfort needed over long distances.

Rigidity and power transfer

High performance carbon construction

The RC910 retains the competition positioning that characterizes the S-PHYRE range. Its carbon construction is designed to offer an extremely rigid and stable platform in order to efficiently transmit the power generated by the cyclist to the pedals.

Shimano stiffness index 12/12

With a Shimano stiffness rating of 12/12 , the RC910 sits at the top of Shimano road cycling range. It is particularly suited to cyclists looking for a very stiff shoe for sprints, accelerations, climbs, and competition.

New Shimano SPD-SLR interface

What is the SPD-SLR?

The RC910 accompanies the arrival of the new generation of Shimano road components with the new SPD-SLR interface.

This system was developed to optimize the interface between the shoe, the cleat and the pedal and to bring the foot closer to the pedal axle.

An optimized shoe, cleat and pedal set

To take full advantage of the new system, Shimano has simultaneously developed the new DURA-ACE PD-R9300 and ULTEGRA PD-R8200 pedals as well as a new generation of SPD-SLR cleats.

The RC910 + SPD-SLR cleat + compatible pedal set thus constitutes the new generation Shimano system designed to optimize stability and power transfer.

Recommended pedals

• Shimano DURA-ACE PD-R9300
• Shimano ULTEGRA PD-R8200

RC910 vs RC903: what's different?

The RC910 is not simply an aesthetic evolution of the RC903. Shimano has reworked several important elements of its S-PHYRE shoe:

• New DYNALAST 2.0 fit with more space at the front of the foot.
• BOA® Li2 positioning revised to improve tightening and retention.
• New lower carbon heel to improve comfort.
• New design conceived around the SPD-SLR interface.
• Maintaining the maximum Shimano stiffness index 12/12 .

How to choose your footwear?

With DYNALAST 2.0, Shimano distinguishes several shoe shapes to better adapt to the morphology of the foot.

• Narrow: designed for narrow feet.
• Standard: suitable for the majority of cyclists.
• Large: provides more volume for wider feet.

The new DYNALAST 2.0 offers in all cases more functional space at the front of the foot to allow the toes to spread more naturally.
