Enlarged lever blades make it easier to use them with long-fingered gloves on, but the lightness of touch required to actuate a shift remains similar to the older iteration. Convenient shift modes like full and semi synchronised shifting can be set using the smartphone app.\u003c\/p\u003e\n\n\u003cp\u003eBrake lever reach is adjustable to accommodate different hand sizes and the auto-adjust design of the hydraulic system ensures that the brake feel is the same regardless of pad wear. Servo Wave technology, borrowed from mountain biking, adds extra power and modulation for increased confidence whilst also giving greater pad clearance. Oversized ceramic pistons, combined with the finned pads, ensure excellent temperature control.\u003c\/p\u003e\n\n\u003cp\u003eEven ease of maintenance has been improved, with the one-way internal fluid circuit and separate bleed port and valve screw simplifying the bleeding process.\u003c\/p\u003e","brand":"Shimano","offers":[{"title":"Right Lever\/Front Caliper \/ Black","offer_id":54293102526810,"sku":"1477228","price":269.0,"currency_code":"GBP","in_stock":true},{"title":"Left Lever\/Rear Caliper \/ Black","offer_id":54293102559578,"sku":"1477225","price":269.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0956\/0827\/5290\/files\/Shimano-Ultegra-ST-R8170-Hydraulic-Disc-Di2-Rear-Left-Lever-and-Caliper-Black.jpg?v=1781186847","url":"https:\/\/checkout.sigmasports.com\/products\/ultegra-st-r8170-hydraulic-di2-lever-and-caliper-17u71","provider":"Sigma Sports","version":"1.0","type":"link"}
