Top of the range, high performance Dura-Ace hydraulic disc brake Di 2 STI's give you control, modulation & power with minimal effort in all riding conditions. Key

Features: With Di 2 technology shifting is easy & precise
- just a light touch, as soft as a mouse click, is sufficient for the front or rear derailleur to instantaneously select the correct gear The removal of traditional mechanical cables in favour of electrical wires eliminates poor shifting caused by contaminates, corrosion & stretching, & also provides effortless gear shifts Simply pressing tactile buttons allows effortless & comfortable shifting even when your hands are cold Shifters are lightweight thanks to carbon fibre lever blades, carbon composite bracket body, & a titanium clamp band / fixing bolt Drop bar STI with shift buttons located in a near identical place to the positions you'd assume shifting using a mechanical Shimano STI Hydraulic brake lever provides excellent stopping power with less effort especially from the hood position Hydraulic reservoir tank provides pad to rotor clearance auto-adjust maintaining braking performance during pad wear Finely tuneable reach adjusters for the levers enable custom fitment for all hands Free stroke adjustment for pad to rotor contact setting Levers are supplied without electrical cables, as these need to be ordered separately to suit Two ports for use with E-tube electric cables Kit contains left hand bled ST-R9170 STI, BR-R9170 flat mount brake calliper with pads, hoses & mineral oil (without rotors or adapters) Weight: 360 grams a pair

With several years of development & working closely with professional teams you can expect extreme accuracy from Shimano's first fully integrated power meter Hollow Tech II 11-speed Dura-Ace chainset.

Features: Accurately calibrated strain gauges are integrated inside both left & right crank arms, this provides a stable measurement system through rotation from both sides for extremely precise data 2% accuracy of strain gauge measured power Bluetooth & ANT with wireless firmware update & data acquisition system Easily rechargeable integrated battery with fully waterproof reliable electric system Hollow outer chainring, giving vast improvements in rigidity & increased weight savings The hollow outer chainring has essentially removed outer chainring flex, hugely improving shift performance making it precise even under high load These industry leading Hollow Tech II cold forged hollow crank arms have evolved to increase rigidity, reduce weight, & improve strength The teeth have been developed to work only in conjunction with the 11-speed chains for enhanced contact providing more efficiency & enhanced power transfer There is a wide range of chainring ratios & crank arm lengths available enabling customisation for all riders & racing disciplines Hollow Tech II integrated bottom bracket design uses a wider bearing placement & larger axle diameter for increased stiffness & efficiency Bottom bracket seal design has a minimal bearing interface gives superbly smooth rolling & increased durability
