Description
The all-new Tech 4 V4 builds on our 25+ years of experience in designing and manufacturing hydraulic braking systems. The Tech 4 uses an all-new internal seal to reduce friction, and the pivot rotates on roller bearings, reducing spring rate. The lower spring rate in turn gives a lighter lever action, reducing rider fatigue and retaining our legendary feel and modulation. The updated V4 caliper uses hybrid-style stainless steel pistons with a phenolic insert allowing smoother movement and less maintenance, while being able to handle high temperatures without heat transfer during extreme use.
