Hope Tech 4 V4 Disc BrakeThe Tech 4 V4 builds on Hope's 25 years’ 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 our legendary feel and modulation. The updated V4 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.Specification30% pressure increase compared with the Tech 3 brakeHinged 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 that 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 3 FeaturesIncreased power versus Tech 3Lever shape updated to provide a more ergonomic shape orientated to provide the best mechanical advantage during braking.Hinged clamp reducing weight and ergonomicsShifter integration improved for more adjustabilityTool free bite point and reach adjustmentsHybrid piston designRigid CNC'd one piece caliperCompatible with a wider range of current shifter optionsSupplied with 1600mm hose so these can be used on the front or rear
