Cervelo R5 Ultegra Di2 Disc Road Bike

Cervelo R5 Ultegra Di2 Disc Road Bike

The Cervelo R5 Ultegra Di2 Disc Road Bike has been conceived as a machine for the mountains, excelling on steep, arduous cols and sinuous, warp-speed descents. A new carbon layup and refined tube sections have helped the frame drop 130 grams from the previous incarnation of the R5 and have resulted in a near-ideal bottom bracket to head tube stiffness ratio. This perfectly poised ratio allows the frame to retain all of the pedalling reactivity so loved by Cervelo’s professional riders but integrates extra front end compliance for a smoother performance across poorly maintained road surfaces. The fork has also been refined to shave weight and grant increased vibration damping but doesn’t do so at the expense of lateral stiffness or strength.

A race-inspired geometry promotes nimble but composed handling, while internally routed brake hoses through the frame afford a clean silhouette and reduce aerodynamic drag. In addition, the frameset has generous tyre clearance, providing room for up to 34mm wide tyres, which will be particularly appreciated when exploring bumpy, less-traversed back roads.

Reserve wheels with lightweight carbon rims afford lively acceleration under power. These rims have broad internal measurements to coax extra performance from wider tyres and rotate around smooth-spinning, reliable DT Swiss 370 hubs. Gear changes are taken care of by the Shimano Ultegra R8100 12-speed configuration that uses its semi-wireless electronic format to shift accurately amongst its vast range of ratios. Stopping duties are enlisted to the matching Ultegra hydraulic disc brakes that stop powerfully and precisely in all weather conditions.

Highlights

• A pro-level bike refined to be a ‘lightweight climber” that also descends with unmatched prowess
• The carbon frame is 16% lighter than its predecessor without sacrificing bottom bracket stiffness
• Claimed weight for the frame in a size 56cm is just 703 grams
• The sophisticated carbon layup of the frame offers an optimal bottom bracket to head tube stiffness ratio
• The perfect bottom bracket to head tube stiffness ratio results in a responsive but markedly more compliant ride
• The fork weighs just 329 grams, retains lateral stiffness but reduces longitudinal stiffness to donate extra comfort
• Using Cervelo’s tried and tested race geometry, handling composure and reactivity are assured
• Fully internally routed brake hoses reduce drag by 25 grams and give a clean aesthetic
• Huge tyre clearance permits the use of up to 34mm wide rubber
• Lightweight, wind tunnel honed carbon Reserve wheels with DT Swiss 240 hubs are nimble uphill and fast in the valleys
• A Shimano Ultegra R8100 Di2 12-speed gear configuration changes flawlessly via its semi-wireless electronic format
• Shimano Ultegra R8100 hydraulic disc brakes stop with control and power in all conditions
• The carbon handlebar and stem are light, stiff and neatly channel the brake hoses
• The full carbon seatpost is 20 grams lighter that previously and is tuned for extra in-the-saddle comfort
