Shimano GRX 810 11 Speed ShifterThis brilliant 11 speed model is ideal for use on rough roads, gravel and mud as it delivers top-level shifting performance. Featuring off-road inspired lever and bracket ergonomics, you'll benefit from greater mixed terrain control wherever the road takes you. Shimano has also fitted this version with an anti-slip brake lever which makes it perfect for braking in any weather conditions. Additionally, its easy to use design has been carefully sculpted for maximum grip and control, allowing you to maintain your momentum on challenging terrain.High-Performance 11 Speed ShifterFully-equipped with industry-leading technologies, you'll benefit from the same light shifting operation as top-tier systems but at an affordable price. The RX810 shifter's reach adjust technology allows you to customise its feel to suit your hand size, riding style and individual preferences. Raising the benchmark for gravel riding performance, its Servo Wave lever gives you superior braking actuation and control thanks to its fast action. Minimal effort is needed to control your ride due to its power multiplication factor which rapidly increases pad-to-rim contact.Features: Use: Gravel, Road Oil: Mineral oil Speed: 11 speed Reach Adjust: Tooled Clamp Band Inner Diameter: 23.8-24.2mm Shifter Type: Dual Control Lever Recommended Brake Caliper: BR-RX810 Anti-slip brake lever Shimano Index System Servo Wave ActionTechnologies: Servo Wave Action: When you pull a Servo Wave brake lever, initial pad travel is fast, so little lever movement is needed to bring the pads into contact with the rotor. The power multiplication factor then increases rapidly at the pad-to-rim contact so more of the lever stroke is used to apply greater braking power with improved control. 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.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.

Giro Eclipse Spherical HelmetThe Giro Eclipse Spherical Helmet has been created to offer refined aerodynamic performance matched with agressively cool airflow and the best in head-protecting technology. For road and gravel racing and training it's the ultimate pick.Thanks to its smooth, streamlined design, the Eclipse Spherical Helmet delivers low-drag performance for fast riding. But of course it's not just about speed, it also gives you a mix of technology to keep you safer in the event of a crash. This mix of technologies includes Spherical Technology™, power by MIPS® brain protection systems, and Giro's own Progressive Layering™ construction. At it's heart the in-mould design features a shock-dissipating EPS foam liner, protecting your head in an impact. And here the Progressive Layering™ also focuses on providing separate inner and outer layers to manage high and low-speed impacts.To the outside, the polycarbonate shell offers a durable and tough layer to resist knocks and bumps and this coverage extends fully to the bottom for maximum coverage. Spherical Technology powered by MIPS® (Multi-Directional Impact Protection System) As you'd expect, all Giro helmets are designed to not only meet but also exceed stringent safety standards. The ball and socket Spherical Technology, powered by MIPS, allows the outer liner to rotate around the inner liner during a crash, ensuring you enjoy an extra level of brain-protecting technology, designed to redirect energy and provide more protection in certain impacts.This system also eliminates contact of plastic and slip planes with your skin, boosting your overall riding comfort.Airflow OptimisedWhen you're pushing out the watts, you'll soon be feeling the heat and building a sweat. But here the 14 Wind Tunnel™ vents deliver the airflow you need to stay cooler when a more intense pace starts to bite. Once the air is inside it's channelled over your head to boost comfort while sweaty air is expelled out the back. This cool airflow is complemented by the Ionic+™ anti-microbial padding. With its resistance to bacteria, this padding keeps you feeling fresh and prevents that itchy feeling that comes with less premium padding. Roc Loc® Air 5 SystemSetting the standard for ease of adjustment, stability and comfort, the Roc Loc® Air 5 System ensures you always get the right fit of your helmet. It allows for precise adjustment, with both fore-aft tilt and single-hand dial adjustment. It also allows for uncompromised airflow to your head. The design allows a smooth passage of cooling air through the vents and along the inner air channels. And it’s lighter than comparable systems too, making it the ultimate in skull-hugging luxury.Features:In-Mould polycarbonate shell with EPS linerFull lower hardbody coverageSpherical Technology™Progressive LayeringNanobead EPS foamIonic+™ anti-microbial paddingReflective decals14 Wind Tunnel™ vents and deep internal channellingBuy Giro Helmets from Chain Reaction Cycles, the World's Largest Online Bike Store.
