NOT A SINGLE WATT
LEFT BEHIND

Power generation is hard enough. Riders don't need to lose watts to the physics of aero drag, friction or overheating. S-PHYRE is engineered to limit losses through technological advancements that only SHIMANO could invent.

INCREASED SPEED BY REDUCING DRAG, FRICTION AND EXCESS WEIGHT

STRONGER PERFORMANCE BY REGULATING TEMPERATURE AT ALL LEVELS OF EXERTIO

MAXIMIZED POWER TRANSMISSION AND COMFORT

  • PHYSICS

    Speed lives in the details. We have re-considered everything about how drag, friction and excess weight fight against forward movement. Patterns are fine-tuned, materials are selected to reduce drag and constructions are engineered to limit rotating mass.

  • PHYSIOLOGY

    Heating/cooling demands are a variable driven by exertion and situation. Controlling and maintaining body temperature delivers more power, more consistently, in more situations. S-PHYRE works intuitively to maintain optimal body temperature so the rider can concentrate on power generation.

  • LINKAGE EFFECT

    S-PHYRE linkage effect is built on SHIMANO core System Engineering philosophy. One piece interacting in harmony with the next provides a higher level of performance. S-PHYRE products are designed to unify the rider, gear and bike. Because suffering should come from the effort—not from what you wear.

    S-PHYRE lives up to everything you expect from SHIMANO, and everything we demand from ourselves.
