37°C
TEMPERATURE
REGULATION

Research has proven that 37°C is the optimal core body temperature for riders to deliver power and remain comfortable. Regulating rider body temperature across changing weather conditions and varying intensity levels is uniquely challenging. SHIMANO 37°C is designed as a year-around system to help optimize rider comfort and efficiency.

With 37°C, we factor in things that are controllable – moisture management, wind penetration, and intensity – based temperature regulation, with things that can’t be controlled – like changing temperature and weather conditions. 37°C utilizes unique combinations of insulating and wind/water blocking fabrics, Dynamic Layering, and strategically placed ventilation.

RIDE INTENSITY IS A CONSTANT VARIABLE


TIME
INTENSITY



HIGH INTENSITY RIDING
Heat build up from high intensity riding requires riders to dissipate excess heat

MEDIUM INTENSITY RIDING
Apparel should be breathable and allow for active and passive ventilation of excess heat and protection from wind chill moisture

LOW INTENSITY RIDING
Lower intensity riding requires the rider to select comfortable breathable items

 


PASSIVE VENTING
Control body temperature by utilizing aerodynamics to pull overheated air from the body surface.

WIND PROTECTION
Shield the cyclist from wind chill with wind blocking technologies that conform to the riding position.

HEAT MANAGEMENT
Retain heat in critical areas to maintain core body temperature for sustained performance.

ACTIVE VENTILATION
Regulate body temperature with the use of strategicallyplaced, rider-controlled zippers and vents.

WATER PROTECTION
Guard the rider from the chilling effects of spray, mist, rain, and snow

LAYERING
Utilize innovation to create multiple layers, each working in harmony to maintain rider comfort.
