Hope
The Hope Tech 4 V4 No Rotor Brake Lever/Calliper provides increased power versus Tech 3. The all-new Tech 4 V4 builds on 25+ years of experience designing and manufacturing hydraulic brake systems. The Tech 4 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 the legendary feel and modulation. The updated V4 calliper utilises hybrid style Stainless steel pistons with a phenolic insert allowing for smoother movement and less maintenance, while still being able to manage high temperatures without heat transfer during extreme use.Lever shape has been updated to provide a more ergonomic shape orientation to provide the best mechanical advantage during braking.Hope Tech 4 V4 No Rotor Brake Lever/Calliper FeaturesHinged clamp reducing weight and ergonomicsShifter integration improved for more adjustabilityTool-free bite point and reach adjustmentsRigid CNC'd one piece calliperCompatible with a wider range of current shifter optionsUses post mount, 9.74 callipers with adapters to suit all mount optionsAvailable to fit 160, 180, 183, 200, 203 and 220mm front and rear rotorsChoose either standard or braided hose (braided hose is an extra cost)30% pressure increase compared with the Tech 3 brakeThe hydraulic ratio improved by using a small diameter master cylinder boreMechanical ratio increase for the best balance of increased power and modulation, resulting in usable lever feel throughout the full range of reach and bite point adjustment. The mechanical ratio has been fine-tuned using real riding data to provide its best efficiency at lever forces typically used during riding.A linear relationship between brake pressure and lever force makes it easy and intuitive to control the braking power.Hinged clamp design to reduce weight and reservoir area increased to lower overall stack height. Shifter integration has been improved and now offers 30 of angle adjustment as well as neater packaging and compatibility with the latest shifters. Lateral adjustment on both sides of the master cylinder is also possible to give a wide range of lever position options.Hybrid style pistons consisting of a stainless-steel piston shell, which allow smoother movement and require less maintenance, and a phenolic insert to manage heat transfer during extreme use.The Tech 4 retains the tool free bite point and reach adjustments from the Tech 3All Tech 4 brakes are supplied with new racing compound pads.
