Kahvel: Colnago V4Rs full-carbon aero fork, 375 g claimed, 379 mm length, 43 mm rake; 32 mm max tire clearance
Jõuülekanne: Shimano Dura-Ace Di2 R9200, 2x12-speed electronic (52/36T crank, 11-30T cassette on tested build); frameset offered for SRAM/Campagnolo builds too
Pidurid: Shimano Dura-Ace R9270 hydraulic disc, flat-mount (160/140 mm rotors typical)
Rattad: Shimano Dura-Ace C50 carbon clinchers, 50 mm deep (~1461 g claimed); 700C, thru-axle
Rehvid: Pirelli P Zero Race, 700x28c (clincher); frame clears up to 32 mm
Vedrustus: Rigid (road race bike, no suspension)
Rooliplokk: Colnago CC.01 integrated one-piece carbon bar/stem on top builds (16% more aero than V3Rs cockpit); some builds shipped with Colnago HB R41 bar + Deda Superbox stem; Colnago D-shaped carbon seatpost, 15 mm setback

Verdikt

+Tugevused

Pinpoint, direct, pro-level handling - planted and precise through fast corners and chicanes
Serenely fast: ~3% more aero than V3Rs (13.2 W saved at 50 km/h) for real-world speed gains
4-5% stiffer than V3Rs (Real Dynamic Stiffness) - explosive out-of-saddle acceleration and strong climbing
Light for an aero race bike: 7.15-7.24 kg complete with Dura-Ace Di2 and 50 mm wheels
Improved frame durability vs V3Rs - seatstay breakage rate cut from ~45% to ~10-12% via reshaped stays and less-brittle carbon

−Nõrkused

Geometry is built for pros - long, low and aggressive; amateurs struggle to exploit it
Stiffness costs comfort - more road buzz than an endurance bike on rough surfaces
Eye-wateringly expensive (~£12,599 / €12,630 for the Dura-Ace build)
Shipped with clincher tires rather than tubeless on the tested build
Angular, silver styling alienates traditional Colnago buyers who prefer the C68's heritage looks
