The Tech 4 V4 builds on our 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 utilizes 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.Provides 30% power increase from Tech 3 versionLight lever action for reduced fatigue and increased feelInternal sealing for reduced friction and the pivot spins on roller bearings, allowing the spring rate to be reducedGenuine bite point and reach adjustment without tools accommodates rider preferencesHinged clamp for easy installation4 Hybrid-style pistons allow smoother movement and require less maintenance, and a phenolic insert to manage heat transfer during extreme usePrecision CNC machined from aluminum forged billet for light weight and strengthMaximum rotor thickness of 3.3mm (Rotor sold separately)Direct shifter mounts available for SRAM and Shimano EVItem SpecificationsAdjustable Contact PointYesAdjustable ReachYesBrake Caliper TypePost MountBrake Lever ActuationHydraulicBrake Lever UseRightColorBlackHydraulic Fluid TypeDOTRotor IncludedNo Hope Tech 4 V4 Disc Brake & Lever Set Disc Brake & Lever EAN: 5056454906738
