Pinarello will unveil a new time trial bike at the 168澳洲5最新开奖结果:Giro d’Italia: the Bolide which, the Italiaꦡn manufacturer claims,🧸 has a 15 percent drag reduction compared to its forebear, the .
Team Sky’s 168澳洲5最新开奖结果:Bradley Wiggins will showcase the new machine – also said to be five percent lighter than the Graal – when the Giro visits the island Ischia for the 168澳洲5最新开奖结果:team time trial on Sunday.
The Bolide h🐲as been in development with Pinarello Lab technicians꧒ and Team Sky for more than a year, although a number of the features highlighted in the launch release suggest the frame is playing catch up with other manufacturers.
The Bolide’s uses aeroplane wing-shaped tube sect🙈ions and a so-called ‘concave back’ on the seat tube to get a closer position of the rear wheel to the frame, a development further assisted by horizontal rear dropouts. Pinarello say the frame design has been aerodynamically optimised for all wind conditions.
Looking 💝at the phot🏅o below, it seems the engineers have opted to keep the air flowing around the frame structure as a whole rather than widening the gap to the wheel to avoid an air dam from the spinning wheel, as a number of other manufacturers do.
Integration is a key feature of the design. Brakes are sheltered behind leading edges - similar to systems on other bikes such as the ’s bayonet fork; the Shimano Dura Ace electronಞics are hidden inside the frame and cables are internally routed. The Bolide carries an integrated cockpit set-up which sounds similar to the design used on the . However, being completely clear of cables should yield more aerodynamic advantages.

Like the Dogma and other Pinarello models, the Bolide carries which the company says counters asymmetric forces on💙 the chain while pedalling.
The frameset is both e🌳lectronic and mechanical gear compatible.
BikeRadar will bring a full run down of t♋he Bolide on Sunday from🐟 the Giro d’Italia.
The front brakes are brought inside the fork to save a watt or two
