Tool free bite point and reach adjustments allow easy customisation for individual rider preferences, while lateral adjustment on both sides of the master cylinder provides a wide range of lever positions.\u003c\/p\u003e\n\n\u003ch2\u003eAdvanced Caliper Construction\u003c\/h2\u003e\n\n\u003cp\u003eThe rigid, CNC machined one-piece caliper features a hinged clamp to reduce weight and reservoir area, lowering overall stack height. Hybrid pistons combine stainless steel shells for smooth movement with phenolic inserts to manage heat during extreme use.\u003c\/p\u003e\n\n\u003ch2\u003eShifter Integration and Compatibility\u003c\/h2\u003e\n\n\u003cp\u003eShifter integration has been improved, offering 30 degrees of angle adjustment and compatibility with a wider range of current shifter options. The brake is compatible with post mount 9.74 calipers, using adapters to suit all mounting options and rotor sizes of 160, 180, 183, 200, 203 and 220 mm.\u003c\/p\u003e\n\n\u003ch2\u003eAdjustable Mechanical and Hydraulic Ratios\u003c\/h2\u003e\n\n\u003cp\u003eThe hydraulic ratio has been optimised with a small diameter master cylinder bore, while the mechanical ratio has been fine-tuned using real riding data. This ensures an intuitive linear relationship between lever force and brake pressure, providing a usable feel throughout the full range of reach and bite point adjustments.\u003c\/p\u003e\n\n\u003ch2\u003ePads and Finishing\u003c\/h2\u003e\n\n\u003cp\u003eAll Tech 4 brakes are supplied with new racing compound pads, offering excellent performance straight from the box with improved fade resistance compared with standard organic pads. The complete brake is available in black, purple, red, orange, blue and silver, and can be fitted with either standard or braided hose, with braided hoses available at extra cost.\u003c\/p\u003e","brand":"Hope Technology","offers":[{"title":"Right Lever\/Front Caliper \/ Black\/Blue","offer_id":54295465165146,"sku":"1598378","price":150.99,"currency_code":"GBP","in_stock":false},{"title":"Left Lever\/Rear Caliper \/ Black\/Blue","offer_id":54295465197914,"sku":"1598377","price":150.99,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0956\/0827\/5290\/files\/Hope-Technology-Tech4-E4-Brake-Lever-and-Calliper-Black-Blue.jpg?v=1781213021","url":"https:\/\/checkout.sigmasports.com\/products\/tech4-e4-brake-lever-and-caliper-y9bb","provider":"Sigma Sports","version":"1.0","type":"link"}
