Rondo Ruut CF Zero Disc Adventure Bike 2019
By mixing XT and Ultegra Di2 components Rondo have been able to produce an electronic shifting, hydraulic braking 1x bike in the Ruut CF Zero Disc Adventure Bike. The wide range of gears is suitable for any off-road adventure thanks to the 11-42 XT cassette and FSA SL-K Light 40 tooth chainring. The Ruut carbon frame features flex points on the seat stays, top tube and seat tube to take the edge off rough tracks and trails on long days out, reducing fatigue and increasing control.
The piece de resistance of the Ruut CF Zero Disc Adventure Bike is the Rondo carbon Twintip fork, which offers two different axle positions to alter the geometry of the whole bike. The LO setting is slacker, more stable and designed for longer endurance rides, whilst the HI setting reduces the fork trail by 13mm and steepens the head angle by half a degree for more agile handling.
Features
- Adjustable head angle and fork trail
- Ruut Flex Design Eps Carbon frame
- Twintip carbon fork
- Shimano Di2 1x Ultegra/XT groupset with hydraulic disc brakes
- Thru axle front and rear
