Whistle Vaero 2 Ultegra Di2 Lite: UCI-Certified T800/T700 Aero Carbon Road Bike at 8.0 kg

The Whistle Vaero 2 Ultegra Di2 Lite sits at the pinnacle of UCI-certified carbon aero road bikes: tipping the scales at 8.0 kg, it is engineered for riders demanding a race-ready machine equipped with a top-tier electronic drivetrain. Within the Whistle road lineup, this build featuring the Shimano Ultegra Di2 R8170 12-speed groupset shaves 200 grams off its sister model, the Whistle Vaero 2 105 Di2, while introducing Dura-Ace-derived shifting and braking technologies paired with a dual-modulus Toray T800/T700 carbon layup, a one-piece integrated carbon cockpit, and Whistle C40 Full Carbon wheels with a 36T Ratchet hub. At Novo Cicli, our in-house technical department prepares every bike prior to dispatch to tailor crank arm length, cockpit dimensions, and gearing ratios to your exact biomechanical fit.

UCI-Approved Toray T800/T700 Aero Frame, Zero-Offset Seatpost and UDH Standard

The Full Carbon frame and fork platform is officially approved by the Union Cycliste Internationale (UCI Approved) for road racing, blending aerodynamic efficiency, torsional stiffness during out-of-the-saddle sprints, and high-frequency vibration damping:

• Dual-Modulus Toray T800 and T700 Carbon Layup: High-modulus T800 carbon fibers reinforce the PressFit 86.5x41 mm bottom bracket shell and tapered head tube for immediate watt transfer, while T700 fibers in the rear triangle absorb road chatter over long distances.
  
  
• Zero-Offset Aero Seatpost and 30 mm Tire Clearance: The dedicated 360 mm carbon aero seatpost with zero setback (0 mm Offset) positions the rider directly over the bottom bracket for optimal vertical power delivery, while the 12 mm thru-axle frame and fork come fitted as standard with 700x30c Continental Grand Prix tires to lower rolling resistance.
  
  
• Universal Derailleur Hanger (UDH): The rear dropout adopts the UDH standard, eliminating hanger flex during high-load electronic shifts, protecting the carbon rear triangle in the event of an impact, and ensuring worldwide spare part availability.

Complete Shimano Ultegra Di2 12-Speed Groupset, C40 Ratchet 36T Wheels and One-Piece Cockpit

The mechanical specification of the Whistle Vaero 2 Ultegra Di2 Lite elevates shifting speed under load, braking modulation, and rotational responsiveness:

• Shimano Ultegra Di2 R8170 (2x12) Electronic Groupset with Hyperglide+: The Ultegra CS R8101 (11/34T) cassette utilizes Hyperglide+ tooth profiles to allow seamless up- and down-shifting even under full pedaling torque. Wireless ST R8170 dual-control levers feature programmable top hood buttons to control your cycling computer hands-free and Servo Wave technology on the BR R8170 hydraulic calipers (160/140 mm rotors), delivering a shorter lever stroke and wider pad-to-rotor clearance to prevent disc rub.
  
  
• Whistle C40 Full Carbon Wheels with 36T Ratchet System: A 40 mm deep carbon wheelset (Tubeless Ready rim bed, CenterLock rotor mount, and Shimano HG freehub body) built around a 36-tooth Ratchet rear drive ring system, providing a rapid 10-degree engagement angle for instant acceleration out of corners.
  
  
• Whistle Vaero One-Piece Carbon Cockpit: A monocoque Full Carbon integrated bar-and-stem unit that routes all hydraulic hoses completely internally through the oversized 1.5-inch FSA No.55R headset (ACR system), eliminating frontal airflow turbulence.

The Novo Cicli Advantage: Factory Sizing Adaptation, Custom Gearing and Pro Setup

From the factory, the Whistle Vaero 2 Ultegra Di2 Lite ships with preset integrated cockpit and crank arm dimensions tied to frame size (100x400 mm cockpit with 170 mm cranks on sizes 49 and 52; 110x420 mm with 172.5 mm cranks on sizes 54 and 56; 120x440 mm with 175 mm cranks on size 58). At Novo Cicli, our technical department intervenes before shipping to adapt the bike to your biometric measurements:

• Crank Length, ACR Cockpit and Saddle Setback Customization: Upon request, we swap the stock Ultegra crankset for alternative arm lengths (such as shorter 165 mm or 170 mm cranks to optimize cadence and hip angle), adjust handlebar reach and width via the FSA ACR standard, and dial in your exact saddle height and setback on the Zero-Offset seatpost.
  
  
• Race Gearing Changes and Tubeless Conversion: For criterium or fast road racing, we can replace the stock 50/34T compact chainrings with a 52/36T mid-compact setup or install a close-ratio 11/30T cassette, as well as perform a full tubeless conversion on the C40 carbon wheels prior to collection in Besnate (Varese, Italy) or insured international delivery.
