Vitus Auro CR Triathlon Bike (105). The Auro CR is an ultra-efficient, UCI approved Triathlon and TT road bike. This bike features a re-engineered frameset construction to provide even more performance, adjustability and tyre clearance than its predecessor, the Crono Shimano 105 R7000 11 Speed Drivetrain. The Auro has an aerodynamically optimised high-modulus carbon frame and fork at its core, with internal cable routing and an integrated carbon fibre aero stem. It’s also equipped with a Shimano 105 drivetrain, complete with Tektro direct mount caliper brakes, with the rear mounted underneath the chainstays for superior aerodynamic efficiency Prime Black Edition Aerodynamic Wheels. This bike has ultra-efficient Prime Black Edition wheels rolling beneath it. These exceptional wheels feature performance-enhancing rim depths of 65mm on the front and 80mm on the rear. This variating rim depth is optimised to provide the perfect balance of aerodynamic efficiency and cross-wind stability, plus, they are wrapped in all weather, high-grip Vittoria Rubino tyres. Vitus completed this race-dominating bike build with a superb finishing kit, including Zipp Vuka handlebars, which come complete with aero handlebar extensions Features: Frame: Carbon T700-HM UDForks: UD Full carbon aero bladedBottom Bracket: PF30Brakes: Tektro T531 / T541 Direct Mount CaliperDrivetrain: Shimano 105 R7000 Shifter: Vision TriMax 11 SpeedFront Derailleur: Shimano 105 FD-R7000 Rear Derailleur: Shimano 105 RD-R7000 SSCassette: Shimano CS-R7000 11-30TChainset: FSA Gossamer Pro 11spd 53/36TChain: KMC X11-1 with Quick-LinkWheels: Prime Black Edition F65mm/R80mm Full Carbon Clincher Tubeless ReadyAxles: QR (rear horizontal dropout)Tyres: Vittoria Rubino IV 25cSaddle: Vitus TTSeatpost: Vitus Auro Carbon AeroStem: Vitus Integrated Carbon AeroHandlebar: Zipp Vuka AluminaAero Extensions: Zipp Vuka Alumina EVO 70 (variable height risers supplied)Headset: Aero IntegratedTop Cap: Aero IntegratedEasy Assembly.
