Understanding Shimano Indexed Shifting (S.I.S)
Every Shimano equipped multi-gear bicycle includes Shimano S.I.S - Shimano Indexed Shifting. It's the technology behind that "click" you hear and feel everytime you shift through your gears. That "click" captures the light, precise, and consistent shifting bikes equipped with Shimano deliver. It's the sound of perfect gear changes, of levers directing derailleurs in harmony, and the feeling that resonate into your hand, letting you know that your commands are being answered.
S.I.S technology can be found at the core of every Shimano shifting system, and this innnovative technology invented first by Shimano, benefits every type of cyclist. Whether you ride for fun, fitness, commuting, or competing - and on pavement or trail - Shimano S.I.S is a foundation of your cycling experience.
If your bike has multiple gears, and if your bike is equipped with Shimano shift lever, you have S.I.S shifting technology at the tip of your fingers.
While S.I.S is a cornerstone of Shimano shifting, your bike may also include other components that are "System Engineered" to work together in harmony. This includes gears with teeth designed to provide added consistency and smoother shifting, especially when paried together with Shimano chains.
Your bicycle equipped with Shimano drivetrain components are designed to work together - with the ultimate goal of making your ride more fun and enjoyable, no matter path you decide to take. This peace of mind allows you to spend less time worrying about your components and more time enjoying the ride.
All of this technology is backed by Shimano's 3-2-1 Warranty, for dependability and your peace of mind.
