Chronos Bianco Cycling Shoe - Wahoo Speedplay Direct Mount

With the Chronos White Speedplay model, achieve the lowest possible stack height.

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

Reduced stack height thanks to 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 the final stages of a race.

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

Low stack height for efficient biomechanics

The shoe's stack height 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, the foot sits close to the pedal axle, reducing leverage on the ankle and calf muscles. This results in more direct power transfer, greater stability, and less muscle fatigue, helping you pedal efficiently and tackle the run with fresher legs.

An aerodynamic design with measurable benefits

Aerodynamics is crucial when riding solo at high speeds. This shoe uses a single dial closure system, covered by a smooth lace cover that closes with a zipper. By reducing surface texture and airflow turbulence around the instep, aerodynamic drag is lower compared to conventional closure systems. Wind tunnel and road tests 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 wear, remove, and carry, even in the rain

Made in one piece, the shoe seamlessly transitions from a rigid carbon shell to softer upper sections, ensuring comfort and easy fitting. The carbon shell includes drainage holes to prevent water buildup, while the upper is made of lightweight, sustainable, and antibacterial microfiber leather.

Efficient pedaling without tying your shoes

Designed for seamless transitions, this shoe allows immediate power transfer to the pedals, even if not fully tied. The easily thermoformable carbon shell perfectly wraps the foot, optimizing every pedal stroke for maximum efficiency, especially during high power transfers and accelerations.

A stiff carbon shell that saves energy for the run

The solid carbon shell sole provides exceptional support and stabilization for the entire foot, especially the heel. Its unique shell shape helps relieve calf tension, allowing you to use hips and thighs to pedal. This strategic design conserves energy for your run, giving you an advantage when it matters most.

Key benefits at a glance:

• Aerodynamic design with measurable benefits, thanks to the shoe’s smooth surface and lowered body position
• Better power transfer, even with shoes not fully tied
• Legs full of energy for the run thanks to optimal support and stabilization during pedaling
