Ride through the gravel and mud with this stunning model which delivers stress-free operation on the bumpiest of rides. It features some of the most sought-after technologies including the revolutionary Di2 shifting system which gives you instant, precise and lightning-fast shifts. To top it off, its raised hood prevents slipping, so you can enjoy improved confidence and grip on rough surfaces and descents. Technologies: Di2: The revolutionary Di2 shifting system solves the challenges drivetrains present to the power-delivery equation in cycling. Di2 gives you instant, accurate, lightning-fast shifts the first and every time, at the push of a button. Even in the most extreme conditions, shifting is precise and controlled. You can change gear even under heavy load while climbing or accelerating. With Di2, you are in complete control. E-Tube: The E-Tube platform's “Plug & play” and D-Fly wireless connections make it easier than ever to check the system's status and apply customised settings to Di2 and Shimano Steps components with a PC, tablet or smartphone. SEIS: A technological innovation of the computerised shifting system based on the Di2 concept with which is called, the SEIS (Shimano Electronic Intelligent System). The SEIS innovative shift technology is still based on the Shimano Index System (SIS) that has proved its superior gear changing characteristics over the years. The big difference is that in this case, the shifting action is provided for by electronics instead of mechanics. This electronic shifting system has been extensively tested over past two years by several professional riders in all conditions possible, such as rain, mud, low temperatures, cobblestone roads and combinations of all of these at the same time. Shifting is executed by simply pressing the button. No power is needed to shift, which gives important advantages since it is easier now to always keep a tight grip on the handlebar and to keep your concentration on riding instead on shifting. The shift system allows accurate and effortless shifting in difficult circumstances for example when you have cold hands or when you are completely exhausted. Furthermore, the shifting performance will never be affected by contaminated or stretched cables since the shifting signal is transferred electronically. The operating buttons work similarly to the mechanical Dual Control Lever, so you don’t need to re-program your mind for the SEIS. Reach Adjust: Brake lever is equipped with a reach adjust mechanism. The distance from handlebar grip to lever can be adjusted to suit any hand size, type of riding and individual rider preferences.
It features a sleek lever which gives you smooth and effortless operation thanks to its redesigned internal shifting unit. Simple to set up and maintain, its robust caliper provides you with the excellent ergonomics and technologies found on Shimano's top-of-the-range Dura-Ace series. This perfect combination raises the bar for entry-level performance at an affordable price. Technologies: Shimano Index System: Every Shimano equipped multi-gear bicycle includes Shimano S.I.S - Shimano Indexed Shifting. It's the technology behind that "click" you hear and feel every time you shift through your gears. That "click" captures the light, precise, and consistent shifting bikes equipped with Shimano deliver. It's the sound of perfect gear changes, of levers directing derailleurs in harmony and the feeling that resonates into your hand, letting you know that your commands are being answered. Reach Adjust: Its brake lever is equipped with a reach adjust mechanism. The distance from handlebar grip to lever can be adjusted to suit any hand size, type of riding and individual rider preferences. Ice Technologies: The fade, which can occur to disc brake rotor and pad when braking on a long downhill ride has a negative impact on the braking performance. Shimano has adopted Ice Technologies disc brake rotor's and Ice Technologies pad's to realise the cooling technology for consistent performance. The clad disc brake rotor blade, which has a 3 layer-sandwich structure of stainless steel, aluminium and stainless steel, provides better radiation performance achieving from 400˚C to 300˚C surface temperature. Also, the radiation fin has been adopted for the pad. Moreover, the clad disc brake rotor blade and the radiator fin provide long pad life, less noise, less fade and lightweight. One Way Bleeding: One Way Bleeding was developed for quick and easy prevention of air in our hydraulic system. We have streamlined the oil route throughout the system to prevent air bubbles from being captured in the system. One way oil routing plus a funnel tool with mineral oil provides an easy and clean bleeding system. Click here to view the Shimano Brake Reference Guide.
This brilliant set gives you more intuitive braking control, so you can tackle all the challenges of a long day out on the road. It features a lever with ergonomics inspired by the 105 series for greater comfort and actuation in all conditions. Easy to set-up, its reach adjust range is customisable to suit your hand size, type of riding and individual preferences. What's most impressive, is it gives you the same level of shifting operation as more high-end groupsets at an affordable price point. Enjoy the optimised low weight, high rigidity and heat dissipation of its caliper wherever the road takes you. This stunning model features oversized pistons which transfer hydraulic power directly to the brake pad for more efficient stopping power. Shimano has also carefully constructed it from ceramic material to avoid heat transfer for constant stable braking and high-performance even on long downhill stretches. This is a perfect choice of upgrade for riders who want a 30% increase in brake power in comparison to previous models and upgraded technologies from the Dura-Ace and 105 series.

The updated ergonomic design of the Shimano Ultegra ST-R8070 Di2 11 Speed STI Road Levers clearly separates the shift buttons so you can shift easily and efficiently, even in the depths of winter when you're wearing thick gloves. Designed for Hydraulic Brakes The ST-R8070 dual control lever is designed specifically for use with hydraulic brakes for excellent rider feel and control in all conditions. Multi-Shift Each switch on the Shimano Ultegra ST-R8070 can be used to multi-shift. Additionally, the top hood buttons can be programmed and customised through the Shimano E-Tube app or PC software to control third-party devices. Technologies: Di2: The power and precision of Di2 is unmatched. It enables beautifully smooth shifting both front and rear. The lack of maintenance and adjustment is impressive: once you’ve customised your Di2 to shift to your preferences, it will continue to do so endlessly. E-Tube: Change all Di2 functions and operations through the shifter buttons behind the brake levers, the top hood buttons or satellite buttons for TT/Triathlon, sprinting and climbing. You can easily customise shift speed, multi-shift options and Synchro Shift. You can also customise the top hood buttons to control third party-devices, for example to scroll through bike computer menus. The functionality on third-party computers also allows you to display Di2 system information, such as battery level and the gear you’re in.
