The Tech 4 E4 builds on Hope brand's 25+ years of experience in 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 Hope's legendary feel and modulation.
The updated E4 caliper 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.
