{"product_id":"hope-tech-4-evo-trial-zone-disc-brake","title":"Tech 4 EVO Trial Zone Disc Brake","description":"\u003cp\u003eThe Tech 4 EVO Trial Zone is Hope's dedicated trials brake, pairing the latest EVO lever with the brand's two-piston Trial Zone caliper. Trials is all about precise, repeatable control at very low speed, and this set-up is built for exactly that - big stopping power when you need to lock up on an edge, with a lever feel that stays predictable from first bite to full squeeze.\u003c\/p\u003e\n\u003cp\u003eThe EVO lever brings a new cam mechanism that cuts down the free stroke before the pads bite, while keeping modulation through the braking zone. A second guide bush keeps the piston running dead straight for a smoother action, and there's now a bleed port on the master cylinder body, so you can bleed the brake without taking the lid off. Tool-free reach and bite point adjustment carry over from the Tech 3, and the hinged clamp gives 30° of shifter angle adjustment plus lateral adjustment on both sides of the master cylinder.\u003c\/p\u003e\n\u003cp\u003eDown at the wheel, the one-piece CNC-machined caliper runs two big 25mm aluminium pistons for power and stiffness, and it's designed to work with Hope's Trial Zone rotors. Hope quotes a 30% pressure increase over the Tech 3, thanks to a smaller master cylinder bore and a reworked mechanical ratio tuned using real riding data. Sold as a single brake with standard black hose and no rotor, in seven colours.\u003c\/p\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eTrials-specific brake with Tech 4 EVO lever and Trial Zone caliper\u003c\/li\u003e\n\u003cli\u003eNew cam mechanism reduces free lever stroke while keeping modulation\u003c\/li\u003e\n\u003cli\u003eSecondary guide bush for smooth, straight piston movement\u003c\/li\u003e\n\u003cli\u003eMaster cylinder bleed port - bleed without removing the lid\u003c\/li\u003e\n\u003cli\u003eTwo 25mm aluminium pistons in a rigid one-piece CNC caliper\u003c\/li\u003e\n\u003cli\u003e30% pressure increase compared with the Tech 3 brake\u003c\/li\u003e\n\u003cli\u003eLinear relationship between lever force and brake pressure for intuitive control\u003c\/li\u003e\n\u003cli\u003eTool-free reach and bite point adjustment\u003c\/li\u003e\n\u003cli\u003eHinged clamp with 30° shifter angle adjustment and lateral lever adjustment\u003c\/li\u003e\n\u003cli\u003eDesigned to work with Hope Trial Zone rotors\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eSpecification\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eLever: Tech 4 EVO\u003c\/li\u003e\n\u003cli\u003eCaliper: Trial Zone, one-piece CNC-machined\u003c\/li\u003e\n\u003cli\u003ePistons: 2x 25mm aluminium\u003c\/li\u003e\n\u003cli\u003eCaliper mount: Postmount\u003c\/li\u003e\n\u003cli\u003eHose: Standard black hose only\u003c\/li\u003e\n\u003cli\u003eRotor: Not included - designed for Hope Trial Zone rotors\u003c\/li\u003e\n\u003cli\u003eLever side: Left or right hand (sold singly)\u003c\/li\u003e\n\u003cli\u003eColours: Black, Blue, Orange, Purple, Red, Silver, Smoke\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Hope","offers":[{"title":"Blue \/ Left Hand \/ Black Hose","offer_id":56009138274678,"sku":"T4ETZBR9L","price":199.95,"currency_code":"GBP","in_stock":true},{"title":"Blue \/ Right Hand \/ Black Hose","offer_id":56009138307446,"sku":"T4ETZBR9R","price":199.95,"currency_code":"GBP","in_stock":true},{"title":"Orange \/ Left Hand \/ Black Hose","offer_id":56009138340214,"sku":"T4ETZCR9L","price":199.95,"currency_code":"GBP","in_stock":true},{"title":"Orange \/ Right Hand \/ Black Hose","offer_id":56009138372982,"sku":"T4ETZCR9R","price":199.95,"currency_code":"GBP","in_stock":true},{"title":"Smoke \/ Left Hand \/ Black Hose","offer_id":56009138405750,"sku":"T4ETZKR9L","price":199.95,"currency_code":"GBP","in_stock":true},{"title":"Smoke \/ Right Hand \/ Black Hose","offer_id":56009138438518,"sku":"T4ETZKR9R","price":199.95,"currency_code":"GBP","in_stock":true},{"title":"Black \/ Left Hand \/ Black Hose","offer_id":56009138471286,"sku":"T4ETZNR9L","price":199.95,"currency_code":"GBP","in_stock":true},{"title":"Black \/ Right Hand \/ Black Hose","offer_id":56009138504054,"sku":"T4ETZNR9R","price":199.95,"currency_code":"GBP","in_stock":true},{"title":"Purple \/ Left Hand \/ Black Hose","offer_id":56009138536822,"sku":"T4ETZPUR9L","price":199.95,"currency_code":"GBP","in_stock":true},{"title":"Purple \/ Right Hand \/ Black Hose","offer_id":56009138569590,"sku":"T4ETZPUR9R","price":199.95,"currency_code":"GBP","in_stock":true},{"title":"Red \/ Left Hand \/ Black Hose","offer_id":56009138602358,"sku":"T4ETZRR9L","price":199.95,"currency_code":"GBP","in_stock":true},{"title":"Red \/ Right Hand \/ Black Hose","offer_id":56009138635126,"sku":"T4ETZRR9R","price":199.95,"currency_code":"GBP","in_stock":true},{"title":"Silver \/ Left Hand \/ Black Hose","offer_id":56009138667894,"sku":"T4ETZSR9L","price":199.95,"currency_code":"GBP","in_stock":true},{"title":"Silver \/ Right Hand \/ Black Hose","offer_id":56009138700662,"sku":"T4ETZSR9R","price":199.95,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0568\/3065\/6691\/files\/hope-trial-zone-no-9-disc-brake-blue-left-hand-black-hose-1186007461.jpg?v=1756076957","url":"https:\/\/www.biketart.com\/products\/hope-tech-4-evo-trial-zone-disc-brake","provider":"Biketart","version":"1.0","type":"link"}
