Its reach adjust mechanism means the distance from the handlebar grip to the lever can be adjusted to suit any hand size or riding style. Plus the braking area has been expanded to offer more control while braking.HOLLOWTECH II Crankset (2x12-speed 50-34T)HOLLOWTECH II structure cuts weights yet maintains stiffness, strength and performance. What’s more, the crank arm length starts at 160mm so smaller riders can benefit from SHIMANO’s legendary shifting.Rear Derailleur (12-speed)Experience faster, more accurate rear shifting with wireless Di2. A more compact design integrates the wireless unit, charging port and function button. You can check the battery level and Bluetooth/ANT pairing success with your cycle computer/smartphone/tablet. Plus select your preferred shift mode and view adjustment mode information (if you wish to tweak or tune your rear derailleur).Front Derailleur (2x12-speed)The new Di2 wireless platform brings quick and smooth front shifts. And a choice of manual shifts or synchronised shifting assist modes – SEMI-SYNCHRO or FULL-SYNCHRO – which is a bit like having your own personal assistant! In SEMI-SYNCHRO mode, the rear derailleur automatically adjusts to reduce big jumps in gear ratios allowing you to maintain your pace and rhythm. In FULL-SYNCHRO mode, the front and rear derailleurs work in perfect harmony to get you in the right gear at the right time – so you never have to worry about it. Slick communications with the rear derailleur combined with programmed chain guide control minimises chain drop. And top gear teeth capacity is 50-52T. It’s up to you how little or often you think about gear ratios!Cassette Sprocket (11-34T/12-speed)The refined 12-step gear combination ensures excellent efficiency so none of your effort is wasted. You’ll experience faster, smoother shifts under maximum torque (pedalling force) and shifts so smooth you’ll barely notice them – whether biking uphill, downhill or rolling on the flats.Flat Mount - Hydraulic Disc Brake CalliperThe all-new hydraulic disc brake calliper enjoys 10% wider pad clearance than mechanical 105 – meaning less brake rub so less noise. It also brings a simpler, maintenance-friendly brake fluid bleeding process.
