This brilliant set gives you more intuitive braking control, so you can tackle all the challenges of a long day out on the road. It features a lever with ergonomics inspired by the 105 series for greater comfort and actuation in all conditions. Easy to set-up, its reach adjust range is customisable to suit your hand size, type of riding and individual preferences. What's most impressive, is it gives you the same level of shifting operation as more high-end groupsets at an affordable price point. Enjoy the optimised low weight, high rigidity and heat dissipation of its caliper wherever the road takes you. This stunning model features oversized pistons which transfer hydraulic power directly to the brake pad for more efficient stopping power. Shimano has also carefully constructed it from ceramic material to avoid heat transfer for constant stable braking and high-performance even on long downhill stretches. This is a perfect choice of upgrade for riders who want a 30% increase in brake power in comparison to previous models and upgraded technologies from the Dura-Ace and 105 series.

Simple to set up and maintain, its robust caliper provides you with the excellent ergonomics and technologies found on Shimano's top-of-the-range Dura-Ace series. This perfect combination raises the bar for entry-level performance at an affordable price. Technologies: Shimano Index System: 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 every time 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 resonates into your hand, letting you know that your commands are being answered. Reach Adjust: Its 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: The fade, which can occur to disc brake rotor and pad when braking on a long downhill ride has a negative impact on the braking performance. Shimano has adopted Ice Technologies disc brake rotor's and Ice Technologies pad's to realise the cooling technology for consistent performance. The clad disc brake rotor blade, which has a 3 layer-sandwich structure of stainless steel, aluminium and stainless steel, provides better radiation performance achieving from 400˚C to 300˚C surface temperature. 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. 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. Click here to view the Shimano Brake Reference Guide.
This high-quality model gives you the benefit of 30% greater modulation with linear brake operation, resulting in consistent all-around control. When riding out on the road, you'll also enjoy its clear contact feeling and excellent braking efficiency helping you conquer sharp corners and steep descents. This lightweight model is a perfect solution for riders who want to take advance of some of the best Shimano technologies at an affordable price. Technologies: Dual-Pivot Caliper: A lightweight, compact and durable braking system. Dual-pivot caliper brakes have made considerable progress in the reduction of tolerance and deflection as well as in durability. They have achieved a firm and instantaneous braking response while assuring longer service life. Moreover, the brake pads have improved the durability of 100% to help enjoy high-response braking over longer periods. 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 Servo Wave mechanism is adapted to provide quick contact of your shoe to the rim and longer stroke from the initial braking effect for better control. SLR is the essential factor in the Shimano dual-pivot caliper that delivers more braking power than conventional side-pulls. Click here to view the Shimano Brake Reference Guide.
