Bianchi Oltre RC Dura-Ace Di2 Disc Road Bike 2023
Air is funnelled through the Air Deflector fairings on the head tube along the sculpted top tube and through the hole in the integrated carbon stem / handlebar to create a low-pressure area which shelters the rider. Cutouts in the downtube and seat tube allow the wheels to fit snuggly against the frame and offer a smoother profile to the wind whilst the dropped and flattened seatstays also present as small an area as possible to reduce resistance.
Bianchi claims that these developments mean that the Oltre RC is 45 seconds faster than its predecessor over 40km and saves 17 watts at 50kph. Despite all these advances, the frameset is impressively light, meaning that there won’t be a penalty to pay for all the speed when it comes to the mountains.
The Reparto Corse Carbon SBG wheels have different profiles front and rear to better balance handling and drag reduction, with 50mm at the front and 65mm at the back. As Bianchi’s in-house brand, the design of the wheels matches up perfectly with the frame in terms of creating a smooth flow of air over the bike, with particular attention paid to improving performance at great yaw angles. The rims and the Pirelli Pzero tyres are tubeless-ready with frame clearance allowing the use of rubber up to 30mm wide.
The pinnacle product in Shimano’s road groupset range, 12-speed Dura-Ace offers effortless shifting and consistent, powerful braking. The system is semi-wireless which simplifies cable routing and allows connection to GPS head units for gear and battery information to be displayed whilst Shimano’s E-Tube app gives some customisation options. There is also an integrated power meter for measured efforts whilst training or for post-race analysis. Extra pad clearance and improved modulation are provided by the Servo Wave technology in the hydraulic disc brakes for better braking performance and confidence-inspiring control on the descents.
