Rondo HVRT CF 1 Disc Road Bike 2021
Versatility personified, the Rondo HVRT CF 1 Disc Road Bike uses its aerodynamic, full carbon frameset, refined design and accurate components to be a reactive road racer or a resilient road-plus style explorer.
The lightweight, full carbon frame utilises its advanced material layup and aerodynamically tuned tube profiles to be reactive when climbing, spritely when accelerating and to cheat the wind when the pace it at its highest. A torsionally stiff but vertically compliant carbon fork partners the frame and features the TwinTip concept that enables its length and offset to be adjusted to either sharpen or mute the bike's handing in line with the forthcoming ride's requirements. Further adaptability is granted by the frameset's compatibility with either 700c or 650b wheels with the former being used for fast road racing and the latter in conjunction with broad, plush tyres for rough road and track exploration.
HUNT Limitless wheels have a refined wind-cheating profile that is realised in a lightweight but strong carbon construction to offer speed and control within any riding scenario. A Shimano Ultegra mechanical drivetrain provides total reliability and shifts with an exacting nature every time of asking. Hydraulic disc brakes, also Shimano Ultegra, complete the build by donating positive, composed and accurate stopping power no matter the riding conditions.
