Shimano Dura-Ace Di2 (Dual Integrated Intelligence) R671 are the next generation of TT/TRI Shifters. Put to the test in competition and used in victory by pro cyclists in every conditions, including road, across the pavé or mud. These 11-speed shifters have even been used by the 2012 Tour de France Team Sky. Triathletes and Time Trial cyclists won't need to choose a different shifter position, as Di2 makes multiple shift controls possible. The TT/TRI Shifters can be used on the base bars and satellite controls on aero extensions to pick the ideal gear for all riding positions. - A.D. Key Features: The most advanced level of shifting technology: at the touch of a switch Dura-Ace Di2 is quick shifting, smooth, and effortless The removal of traditional mechanical cables in favour of electrical wires eliminates poor shifting caused by contaminates, corrosion and stretching, and also provides effortless gear shifts Simply pressing tactile buttons allows effortless and comfortable shifting even when your hands are cold These switches give the added option of being able to operate the gears from either the aero extension or the ST-9071 Dual Control brake levers Compatible with the FlightDeck computer, measuring important data such as heart rate, altitude, cadence, gear position, battery indicator and allowing you to customise the shifting action of the derailleurs Switches are supplied without electrical cables, as these need to be ordered separately to suit your frame Weight: 95g (per pair, manufacturer claimed)

XTR RT-MT900 Ice Tech rotors providing consistent braking performance through energy control, using revolutionary stainless steel / alloy 3-layer sandwich construction that manages heat while riding The clad steel / alloy / steel rotor construction allows heat generated from braking to radiate quickly through the aluminium core achieving surface temperature drops of around 50 deg C. When used with Ice Tech pads surface temperatures can drop from around 400 to 300 deg C, this provides great improvements in performance all round FREEZA rotors allow the alloy core to extend out from the braking surface as a fin to providing added cooling Ice Tech rotors achieve long pad life, less noise and less fade due to improved heat dispersion Rotors are durable lightweight and rigid, using the proven Shimano Center Lock system giving increased strength and security with an easy set-up Precision cut braking surface improves pad clearing in muddy conditions while aiding cooling under high load Large alloy spider is a highly rigid and lightweight support for the rotor surface Super polished braking surface gives excellent braking performance
