Description
With the most gruelling mountain passes and the fastest descents in mind, Cervelo has developed the R5 Dura-Ace Di2 Disc Road Bike, realising it with a lightweight, climb-centric character that also flies downhill with impressive composure. The frame has a new carbon layup and modified tube shapes to chisel away 130 grams from the previous incarnation and promote a near-perfect bottom bracket to headtube stiffness ratio. These sophisticated design traits allow the frame to retain reactivity and enthusiasm under power while markedly increasing front end compliance for reduced rider fatigue. The fork has also been tweaked to be lighter and to offer extra vibration damping over rough roads but still boasts all the lateral stiffness required for the most aggressive out-of-the-saddle efforts.
Cervelo’s race-inspired geometry links the frame and fork and affords nimble direction changes and balance when on the fastest, most sinuous descents. Despite having a gravity-defying theme, the frameset neatly internally routes the brake hoses, saving 25 grams of aerodynamic drag in the process, and boasts room for up to 34mm wide tyres, which is particularly useful when tackling rutted, less-traversed back roads.
The Reserve wheels complement the frameset’s spritely character, utilising their lightweight carbon rims with front and rear-specific profiles to help the rider surge up steep inclines and remain stable when crosswinds are encountered. Broad internal rim widths help the tyres realise extra grip and comfort, and the DT Swiss 240 hubs spin smoothly and are low maintenance. The top-of-the-range Shimano Dura-Ace R9200 Di2 12-speed gear set-up offers a vast range of ratios for any terrain and changes flawlessly thanks to its semi-wireless electronic format. Stopping duties are enlisted to the matching Dura-Ace hydraulic disc brakes that afford confidence-inspiring stopping power in all conditions.
