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.
