SIS Shimano Index System:

SIS Rear Index Shifting System: The system constituents such as the index mechanism built in the shifter, the frictionless SIS rear index shifting cable and the smooth action rear derailleur realize the Shimano Index System.

Dual Control Lever (DCL):

DCL stands for Dual Control Lever. It has brake and shifting functions in the system and enables easy operation.

Ergonomic innovation is probably more critical to the higher standard performance than the added gearing. The shift internals borrow the robustness from our MTB technology and are so smooth and effortless that one finger shifts front and rear are possible. Indeed, shifting is the ultimate act of Shimano Total Integration, and simply has to be experienced to be understood.

Reach Adjust:

Brake lever is equipped with a reach adjust mechanism. The distance from handlebar grip to lever can be adjusted to suit any hand size, type of riding and individual rider preferences.

Ice Technologies:

Shimano Ice Technologies components deliver more consistent braking performance by reducing heat buildup in the system. This helps prevent brake fade, which can happen when a rider applies the brakes repeatedly and strongly over a short period of time, such as when descending a long, steep hill.

Shimano Ice Technology disc brake rotors and pads reduce heat buildup and provide consistent and reliable braking power available. The rotors feature a 3-layer stainless steel-aluminum-stainless steel sandwich design that radiates heat for better performance. The brake pads have an aluminum radiating fin that helps dissipate heat throughout the system.

Together, Ice Technology rotors and brake pads deliver a quieter ride while reducing brake fade and extending pad life for a more reliable and confident riding experience.

Ice Technology Pad: Available in resin or metal compound, the optional radiation fin pad with a 2-layer back plate (aluminum fin with stainless steel) further improves radiation performance.

Ice Technology Rotor: Clad rotors as well as Clad Brake pads significantly reduce heat build-up in the brake system. This in turn reduces fading, which ensures consistent high performance even on long downhill stretches, It also results in a longer pad life and substantially quieter braking.

Ice Technologies Freeza: Ice Technologies Freeza rotors utilize the 3-layer stainless steel-aluminum-stainless steel sandwich structure to reduce heat buildup.

The inner aluminum layer extends inward with a wide exposed radiator fin that boosts its cooling capabilities.

One Way Bleeding:

“One Way Bleeding” was developed for quick and easy prevention of air in our hydraulic system. We have streamlined the oil route throughout the system to prevent air bubbles from being captured in the system.

One way oil routing plus a funnel tool with mineral oil provides an easy and clean bleeding system.
