The all-new Hope Tech 4 E4 Hydraulic Disc Brake is the culmination of of Hope's 25+ years experience of designing and manufacturing some of the best brakes ever made. With 30% more power than the old Tech 3 E4 along with a lighter lever action, the Tech 4 E4 is a stunningly lightweight and powerful brake ideal for trail and enduro bikes. 30% extra power compared the old Tech 3 leverLever shape updated to provide a more ergonomic shapeHinged clamp reduces weight and improves ergonomicsTool free bite point and reach adjustments for easy, personalised setupRigid CNC'd one piece 4 piston caliper with hybrid piston design for improved reliabilitySupplied with new Racing Compound pads for improved power and modulationThe Tech 4 E4 uses all new internal sealing for reduced friction and the pivot spins on roller bearings, allowing the spring rate to be reduced. The lower spring rate in turn gives a lighter lever action, reducing rider fatigue and keeping our legendary feel and modulation. Not only this, but the updated lever and blade provide a 30% increase in pressure over the Tech 3 lever for a bucket load of extra braking power! The Tech 4 lever also retains Hope's signature tool free bite point and reach adjustments. The updated E4 caliper utilises hybrid style Stainless steel pistons with a phenolic insert allowing for smoother movement and less maintenance, while still able to manage high temperatures without heat transfer during extreme use. If you want the ultimate all-round brake that perfectly blends power, style and reliability, look no further than the Hope Tech 4 E4!

Shimano GRX 815 Di2 2x11 Speed ShifterThis sensational shifter is specially developed to get you through the gravel and mud with stress-free operation. It features some of the most sought-after technologies including the revolutionary Di2 shifting system which gives you instant, accurate and lightning-fast shifts. Improve your grip and confidence on rough surfaces and descents thanks to its raised hood which prevents slipping. This is an ideal upgrade for riders who want to enjoy higher braking efficiency with game-changing electronic technologies. Features: Use: Gravel, Road Speed: 11 speed Reach Adjust: Tooled Type: Dual control lever Oil: Mineral oil Recommended Brake Caliper: BR-RX810Technologies: Di2: The revolutionary Di2 shifting system solves the challenges drivetrains present to the power-delivery equation in cycling. Di2 gives you instant, accurate, lightning-fast shifts the first and every time, at the push of a button. Even in the most extreme conditions, shifting is precise and controlled. You can change gear even under heavy load while climbing or accelerating. With Di2, you are in complete control. E-Tube: The E-Tube platform's “Plug & play” and D-Fly wireless connections make it easier than ever to check the system's status and apply customized settings to Di2 and Shimano Steps components with a PC, tablet or smartphone. SEIS: A technological innovation of the computerised shifting system based on the Di2 concept with which is called, the SEIS (Shimano Electronic Intelligent System). The SEIS innovative shift technology is still based on the Shimano Index System (SIS) that has proved its superior gear changing characteristics over the years. The big difference is that in this case, the shifting action is provided for by electronics instead of mechanics. This electronic shifting system has been extensively tested over past two years by several professional riders in all conditions possible, such as rain, mud, low temperatures, cobblestone roads and combinations of all of these at the same time. Shifting is executed by simply pressing the button. No power is needed to shift, which gives important advantages since it is easier now to always keep a tight grip on the handlebar and to keep your concentration on riding instead on shifting. The shift system allows accurate and effortless shifting in difficult circumstances for example when you have cold hands or when you are completely exhausted. Furthermore, the shifting performance will never be affected by contaminated or stretched cables since the shifting signal is transferred electronically. The operating buttons work similarly to the mechanical Dual Control Lever, so you don't need to re-program your mind for the SEIS. 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.
Shimano GRX 810 Drop Bar Gravel Disc Brake LeverThis stunning brake lever is specifically designed for gravel riding as it gives you greater mixed-terrain control. Its off-road inspired lever and bracket ergonomics deliver the same light shifting operation as top-level systems. This model also features an anti-slip lever, so you can maintain responsive and reliable stopping power in any riding conditions.Features: Use: Gravel, Road Speed: 11 Reach Adjust: Tooled Oil: Mineral oil Technologies: 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: Each brake lever is equipped with a reach adjust mechanism. The distance from the 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.
