Rondo Ruut CF 2 Disc Gravel Bike 2021
With a lightweight frame realised in EPS carbon, the Ruut CF 2 has a lively and responsive character that surges up climbs and leaps away from corners under power. This frame is tuned via Rondo’s Flex Design that manipulates the carbon layup and profile of the seatstays, top tube and seat tube to infuse high levels of vertical compliance without sacrificing pedalling efficiency.
A TwinTip 2.0 Fly carbon fork grants steering precision, comfort and offers two axle positions to adjust its offset and length, making the handling more agile or more relaxed in line with the technicality of the riding ahead. Tremendous amounts of clearance are given by the TwinTip fork and the dropped drive-side chainstay to permit the use of either 700c or 650b wheels with up to 45mm or 2.2” wide tyres respectively.
The Rondo aluminium wheelset is light but robust and can be set up with tubeless-ready tyres. Driving these wheels is the slick-shifting and reliable SRAM Rival 1 drivetrain while stopping duties are charged to the matching Rival hydraulic disc brakes that are accurate and composed in all conditions.
