Shimano GRX 600 2x11 Speed Gravel Disc BrakeThis stunning disc brake provides you with the stopping power and precision needed to tackle all the challenges of gravel riding. Its off-road inspired lever and bracket ergonomics deliver superior mixed terrain control, so you can easily ride across rough roads even in muddy conditions. Shimano has also raised the benchmark for maintaining a strong grip and modulation in any conditions by making the lever from anti-slip construction. Adjustable Gravel Disc BrakeFeaturing some of the best Shimano technologies available, you'll be able to conquer your next adventure, wherever the road takes you. Its reach adjust technology allows you to precisely customise its feel to suit your hand size, riding style and individual rider preferences. Topping it off is its Servo Wave Action technology which delivers fast braking efficiency between your pads and rotor, so you can enjoy more rapid braking power and control. Features: Use: Gravel, Road Speed: 2x11 speed Oil: Mineral oil Reach Adjust: Tooled Clamp Band Inner Diameter: 23.8 - 24.2mm Type: Dual control lever Technologies: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 and Ice Technologies pad 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 check out the Shimano Brake Reference Guides.A 2-year warranty is offered with all Shimano products from Chain Reaction Cycles (3 years on Dura-Ace and XTR products).Buy Shimano Components from Chain Reaction Cycles, the World's Largest Online Bike Store.
