Featuring industry-leading functions and technologies inherited from the Dura-Ace and Ultegra series, this shift/brake lever brings electronic wireless Di2 shifting to a new set of riders. Representing the pinnacle of years of research and development, Shimano 105 Di2 delivers sophisticated ergonomics, 105-optimised gear combinations and an exceptional brake system. For those who have only experienced mechanical shifting and ergonomics, this model marks a new era of affordable performance. Shimano 105 Di2 Dual Control Lever This Shimano 105 shift/brake lever features Di2 electronic shifting for the first time, bringing precise, intuitive gear changes to even more riders. Not only does it offer worry-free Di2 shifting in a compact shifter size, but it also features technologies such as Reach Adjust and customised button functions that allow you to dial in your ideal ergonomics. Reach Adjust This model's brake lever is equipped with a Reach Adjust mechanism. The distance from the handlebar grip to lever can be adjusted to suit any hand size, type of riding and individual rider preferences. E-Tube Project Shimano’s genuine application E-Tube Project Cyclist allows you to customise your bike, update firmware, and maintain it by connecting it wirelessly to your bike. You can also get the more detailed bike maintenance by connecting to your bike by wire with E-Tube Project Professional application. Dual Control Lever DCL stands for Dual Control Lever. It has brake and shifting functions in the system and enables easy operation. Ergonomic innovation is probably more critical to the higher standard performance than the added gearing. The shift internals borrow the robustness from Shimano's MTB technology and are so smooth and effortless that one finger shifts front and rear are possible. Indeed, shifting is the ultimate act of Shimano Total Integration, and simply has to be experienced to be understood. Technologies: - Clean Cockpit: Wireless connection enhances the aesthetic of your bike while keeping shifting lightning fast. - Longer lasting: Uses two CR1632 batteries (battery life: 3.5 to 4 years). - Compact, ergonomic performance cascaded from Dura-Ace. - Raised hood peak improves ergonomics, while a longer hood body increases hand support. - Make Dura-Ace yours with custom button function and adjustable ergonomics. - Easily change button function with the E-Tube app. - Find your optimum lever position with simple reach adjust.

To ensure that the signal goes from the shifter to the derailleurs, the reliability of the electric cable has been proven by repeated field tests in various riding conditions, including extreme temperatures, rain,mud, and cobble stone roads. The removal of traditional mechanical cables in favour of electrical wires not only eliminates poor shifting caused by contaminates, corrosion and stretching, but provides effortless gear shifts. Dura-Ace Di2 requires 2 cables: a handlebar cable set to connect the shifters to a battery indicator junction box or FlightDeck, and the other to connect the handlebar cable to the battery and derailleurs.
Die-extruded PTFE coated inner wire leaves a smooth surface for low friction in use, and stainless steel provides smooth shifting and higher corrosion resistance.
For flat bar road bikes, the Shimano SL-RS700 shift lever provides reliable and intuitive shifting. This Rapidfire Plus lever features 2-way Release and a quick Multi-Shift action.
This Shimano Saint M820 shifter features Instant Release for super-fast shifts, delivering the chain to the next gear the moment the lever is actuated with no hesitation also the Multi Release function allows multiple gear changes from both levers with one sweep, further adding to the speed of shift. The 2-Way release allows the upper shift lever to perform the same Multi Shift function but swings in either direction allowing it to be released by the thumb or index finger.
Light to the touch but positive and crisp, the Vivid indexing on the Shimano SLX M7000 shifter provides a constant amount of shift lever force across all 11 sprockets. The 2-way release allows shifting from various riding positions; the upper lever still performs the same shift function, but it can now swing in either direction allowing it to be released by the thumb or index finger. A pod design allows the use of these shifters with any brake I-Spec B or I-Spec-II level and the removable optical gear display with integrated cover allows the use of these shifters with any brake lever. Mount Compatibility: Bar Mount: Traditional clamp-mounting style were the Shifter mounts to the handlebar via its own clamp I-Spec B: The shifter is mounted directly to the Brake lever and not via its own clamp, this system is found on the likes of the M615, M675, M785 and M985 Shimano brake series (And, is also compatible with most Hope Brakes, including the Hope Tech 3 lever) I-Spec II: Mounting similar to I Spec B above, but newer and is only compatible with the newer Shimano M6000, M7000 M8000 and M9000 series brake lever systems
Fitting new gears or completely overhauling your gear cabling couldn't be easier, as this Shimano Dura-Ace gear cable kit comes with everything you need in one pack. It includes 1.2mm polymer coated inner wires (1x 2100mm, 1x 1800mm), SP41 outer casing for a complete bike (1x 1700mm) and all the required cable end caps. The polymer coated stainless steel inner cable on this Shimano Dura-Ace gear cable set leaves a smooth surface for low friction and reduced sliding resistance providing a lighter quicker shifting operation. The outer casing is lubricated internally along its length with low-friction silicone grease to reduce cable friction. Also, SP 41 outer casing uses a special directional wound construction process that makes for an axially stiff cable that transmits shifting movements accurately and quickly. Plus, this outer casing is lined with a polymer sheath to assist with the smooth operation of the inner cable.
