TECHNOLOGIES
NEW SUPER SLR:
SLR stands for SHIMANO Linear Response. The NEW SUPER SLR design makes use of a friction-reducing mechanism in the caliper, lever and cable that improve response and modulation.
Also for the lever, the SERVOWAVE mechanism is adopted to provide quick contact of shoe to rim and longer stroke from the initial braking effect for better control.
SLR is the essential factor in the SHIMANO dual-pivot caliper that deliver more braking power than conventional side-pulls.
Equipped: TIAGRA/SORA/CLARIS

Outer Casing With Liner

ICE TECHNOLOGIES:
The fade, which can occur to disc brake rotor and pad when braking on a long downhill ride for instance, has a negative impact on the braking performance. SHIMANO has adopted ICE TECHNOLOGIES disc brake rotor and ICE TECHNOLOGIES pad to realize the cooling technology for consistent performance. The clad disc brake rotor blade, which has a 3 layer-sandwich structure of stainless steel, aluminum and stainless steel, provides better radiation performance. Also, the radiation fin has been adopted for the pad. Moreover, the clad disc brake rotor blade and the radiator fin provide long pad life, less noise, less fade and lightweight.
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.



- 100°C reduction in heat
- +5% braking force
- +10% longer pad life
- (vs stainless steel disc brake rotor)
ICE TECHNOLOGY Hose
SM-BH90-SBLS long banjo hose reduces heat at a critical location where heat transmitted from caliper to hose

ICE TECHNOLOGY Piston
ICE TECHNOLOGIES piston in order to achieve optimized lightweight, high rigidity and heat dissipation.
Oversized pistons transfer hydraulic power directly to the brake pad, and ceramic material is used to avoid heat transfer for constant stable braking, providing efficient stopping power transfer without loss.
