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.

Adjustable Float These pedals feature an adjustable free float that can be fine-tuned to ensure you get the correct float movement, which reduces the cycling strain on your knees. Other pedals only allow a pre-set amount of float or no float at all, but the Zero pedals can be adjusted to your personal preference. This helps to ensure you will be comfortable even at the end of the longest days in the saddle, helps to avoid injury and significantly optimises your power output. Dual-Sided Cleat Engagement Another invaluable feature is the dual-sided entry, which means you can just step down on the pedal and go. No more fumbling or looking down to get into the right position, as the cleat’s design and pedal’s shape ensure that you’ll engage quickly and safely without having to stop and think. Maximum Comfort & Performance Unlike traditional cleats, each of the essential foot positioning adjustments can be changed without affecting each other. Three-Way Adjustment ensures you can set up the cleat’s front/rear and side-to-side positions individually and then choose how much float you want. These unique adjustment settings significantly increase comfort and efficiency while dramatically reducing knee strain and fatigue. Cleat Covers Designed for Safer Walking These Zero pedals come with Speedplay's rubberised cleats, which make those off the bike periods less dangerous if your bike's mechanical problem forces an extended walk on the tarmac, or if you feel the need for a coffee stop. Please Note: Zero Aero pedals are not compatible with Speedplay Light Action and X-Series cleats. Zero Aero cleats are not compatible with Light Action and X-Series pedals. Additional Features: · The Zero cleat positions your foot closer to the top of the spindle for improved power transfer · The thin pedal profile of the Zero pedal lets you power through corners where your rivals coast · Built-in grease port for easy bearing lubrication Technologies: Large, Stable Pedalling Platform: The Zero Pedal System provides the same solid connection as conventional single-sided pedals, but with Speedplay's unique, inverted design the cleat provides the platform once the cleat in engaged Quality Without Compromise: Zero pedals use precision cartridge and needle bearings - three of them instead of two found in most other pedals - which allows the Zero to be thinner for a lower stack height, better cornering clearance, and reduced aerodynamic drag. Like all Speedplay Pedal Systems, the locking edges of Zero pedals and cleats are metal-on-metal for durability and safety, unlike competitors who use engagement edges made of plastic True Locking Mechanism: The Zero's locking mechanism does not rely on spring tension for security, so entering and exiting Zero pedals is easy, but unintended release is virtually impossible
