Description
Blending a sophisticated frameset with speed-inspired component choices, the Rondo Ruut X Gravel Bike is an ideal choice for the fastest riders who take part in cyclo-cross races or the quickest of gravel group rides.
The frame makes use of a full EPS carbon construction to be light and tremendously stiff, granting rapid acceleration and enlivened climbing. Sublime levels of comfort are infused into the frame by the sophisticated carbon layup of the seatstays, top tube and seat tube. The laterally rigid but vertically compliant fork partners the frame perfectly and features the TwinTip format that allows its offset and length to be changed, making the handling either more nimble or more composed. Wide and grippy 700c x 45mm and 650b 2.2” tyres can be accommodated by the frame and fork meaning that even the most challenging terrain can be conquered in complete comfort and control.
The HUNT Rondo wheelset is light but robust and teams up with fast, 33mm wide cross-style Schwalbe tyres. A Shimano GRX drivetrain with tighter spaced gearing means that the ideal cadence can be found when racing hard while the matching GRX hydraulic disc brakes stop sharply and with control in all conditions. Completing the build is a narrow, aero-inspired Easton handlebar with no flare that is ideally suited to cyclocross racing.
