Rondo HVRT CF 0 Road Bike 2021
A full carbon, aero-tuned frameset, an innovative design and sophisticated components give the Rondo HVRT CF 0 tremendous versatility, allowing it to seamlessly flip between being an all-out road racing bike and a hardy road-plus adventurer.
The frame is composed of Fly carbon that infuses excellent lateral rigidity for efficient climbing and rapid acceleration while remaining lightweight. Each tube of the frameset is tuned with an advanced aerodynamic profile to help it slice through the wind while keeping the vertical compliance and comfort levels high. The fork uses its highly developed carbon layup to be torsionally stiff while still smoothing bumps and dampening vibrations. This fork features a TwinTip format that allows its offset and length to be adjusted, changing the handling between nimble and reactive for road racing to more composed for rough-road exploration.
The frameset furthers its adaptability by accommodating both 700c and 650b wheelsets, with the former suiting fast riding on the road and the latter, in combination with 47mm wide tyres, being perfect for tackling the harshest roads and tracks.
A HUNT Limitless carbon wheelset is spritely and responsive under power and uses its refined, deep rim profiles to cheat air resistance and remain stable when confronted with crosswinds. A range-topping Shimano Dura-Ace drivetrain shifts impeccably every time of asking, and the hydraulic disc brakes, also Dura-Ace, provide composed and accurate stopping power, even in the teeming rain.
