It pairs the new \u003cstrong\u003eTech Evo lever\u003c\/strong\u003e with the GR4 caliper. A staggered piston layout gives \u003cstrong\u003eabout 6% more power than the Tech 4 V4\u003c\/strong\u003e it replaces, and it's all \u003cstrong\u003eCNC-machined in Hope's Barnoldswick factory\u003c\/strong\u003e.\u003c\/p\u003e\n\u003cp\u003eThe Evo lever brings a reworked cam, a bigger hook on the blade and a bleed port on the master cylinder. That means more grip on the lever, a quicker bite and an easier time in the workshop.\u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTechnologies:\u003cbr\u003e\u003c\/strong\u003e\u003cem\u003e\u003cspan style=\"text-decoration: underline;\"\u003eCam Mechanism\u003c\/span\u003e\u003c\/em\u003e\u003cbr\u003eA redesigned cam cuts down the dead stroke before the pads bite. You get a slightly firmer bite point, then a smooth rise in power through the braking zone, so modulation stays front and centre.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003e\u003cspan style=\"text-decoration: underline;\"\u003eTwin Guide Bush Piston\u003c\/span\u003e\u003c\/em\u003e\u003cbr\u003eThe roller bearing pivot carries over from the Tech 4, and a second guide bush now keeps the main piston running dead straight.

Plenty of power without the on\/off grab, and a lever feel you'll actually want to brag about at the trailhead. Flow mountain bike reckon it took the crown as their favourite brake, and they don't hand that out lightly.
