Road Bike

Reliable Racing Quality for Faster Sports Performance

Flying over roads like the wind, entirely unrestrained, Shimano aims for greater speed and enjoyment. Shimano road bike components respond, backed by a long history of innovative research -- from aerodynamics to ergonomics. This results in smooth, precise, shift changes, a drivetrain system with loss-free propulsion, and a braking system with high reliability. Together, they let the rider concentrate on the ride, for a stress-free enjoyment. Road technologies accumulated in gruelling races where every second counts match the style of each and every rider, novice or pro, to deliver an uncompromising performance. Shimano components are designed for people who love the road, in every part of the world. 

Mountain Bike

Great Performance and Great Fun of MTB Riding

When you're flying down a back woods trail you can't afford to worry about how your bike's going to respond. Shimano design their mountain bike components so they do what you want them to instantly. Shimano components create a more efficient bicycle-to-rider interface that demands less energy. Shimano do that through low-effort and precise shifting systems, and through linear response braking systems that deliver superior power modulation. By using components that work for you, you can focus more on the task at hand: riding your bicycle.
