Chronos Bianco Cycling Shoe - Wahoo Speedplay Direct Mount

With the Chronos Bianco Speedplay edition, you get as low as possible.

Take your performance to the next level with the Chronos Bianco Speedplay edition, featuring a native 4-bolt sole design that eliminates the need for an adapter. This direct mount setup delivers the lowest possible stack height—just 8.5mm from pedal spindle to cleat interface, compared to 11.5mm with an adapter, and significantly lower than traditional road systems like Shimano SPD-SL (16mm) or Look Keo 2 (17.3mm).

Lower stack height through direct cleat integration

This video shows the Wahoo Direct Mount version of the Chronos triathlon cycling shoe in action.

Mounting the cleat interface directly into the carbon shell sole reduces the overall stack height. A lower stack height shortens the lever arm between the pedal axle and the ankle joint, which can reduce calf strain and improve ankle stability—especially during high-torque efforts and in the later stages of a race.

Rather than adding stiffness through the upper or additional closures, this approach focuses on sole geometry and pedal proximity to create a more stable and efficient interface between rider and bike.

Low Stack Height for Efficient Biomechanics

Stack height of the shoe is defined as the vertical distance from the inside of the shoe—measured directly from the carbon shell without the insole—to the cleat mounting surface. With an internal stack height of 7 mm for the Wahoo Direct Mount block, your foot sits close to the pedal axle, reducing the leverage on the ankle and calf muscles. This results in a more direct power transfer, greater stability, and reduced muscular fatigue, helping you ride efficiently and start the run with fresher legs.

The Chronos Aero Long Distance Cycling Shoe Gives You Wings

Experience unmatched comfort, optimal power transmission, and minimal air resistance with this innovative cycling shoe designed for triathletes. The Chronos Aero is engineered to elevate your performance and support your efforts on the road.

An Aerodynamic Design with Measurable Gains

Aerodynamics matter most when riding solo and at higher speeds. This shoe uses a single dial-lock fastening system, covered by a smooth lace shield that closes with a zipper. By reducing surface texture and airflow disturbance around the instep, drag is lowered compared to conventional closure systems. Wind-tunnel and on-road testing show small but consistent aerodynamic improvements, with the exact benefit depending on factors such as yaw angle, foot position, speed, and the shoe used for comparison.

Comfortable to Put On, Take Off, and Wear, Even in the Rain

Crafted from a single piece, the shoe transitions smoothly from a hard carbon shell to softer upper sections, ensuring comfort and ease of wear. The carbon shell includes drainage holes to prevent water accumulation, while the upper is made from lightweight, sustainable, and anti-bacterial microfiber leather.

An Efficient Pedal Stroke Without Fastening Your Shoes

Designed for seamless transitions, this shoe allows for power transfer to your pedals immediately, even if not fully fastened. The easily heat-moldable carbon shell wraps snugly around your foot, optimizing each pedal stroke for maximum efficiency, especially during high power transfers and accelerations.

A Stiff Carbon Shell Saving You Energy for the Run

The solid carbon shell-sole provides exceptional support and stabilization for your entire foot, particularly your heel bone. Its unique shell-like shape helps relieve tension in your calves, allowing you to utilize your hips and thighs for pedaling. This strategic design conserves energy for your run, giving you an advantage when it matters most.

The Advantages in Short:

• Aerodynamic design with measurable gains, thanks to a smooth shoe surface and lower body position
• Improved power transfer, even with shoes that are not fully fastened
• Energized legs for the run due to optimal support and stabilization while cycling
