Kinesis R2 Disc Road Bike 2021
The Kinesis R2 Disc Road Bike brings together a double-butted alloy frame with a unidirectional carbon fork, delivering a light and responsive ride feel, sharp handling and all-day ride comfort. This highly capable road bike will perform well on fast-paced group rides but is ready for the daily commute and more adventurous exploring too, with space for wider tyres and full mudguards.
The full Shimano Tiagra 10-speed groupset is extremely reliable and offers a wide range of gears, allowing you to tackle gruelling climbs, hit the descents fast and put the power down on the flats with equal aplomb. Hydraulic discs take care of stopping and are powerful in both wet and dry conditions. The wheels are built for strength and roll on wide 32mm Continental Grand Sport Race tyres for cornering confidence and fast rolling.
Highlights
- Lightweight double butted 6061 alloy tube blend that delivers a light and responsive ride feel
- Custom full “UD carbon” fork keeps weight low and takes out road buzz whilst feeling direct and accurate at all times
- Rider Fit Geometry is comfortable all day
- Full Tiagra 4720 10-speed groupset
- Hydraulic Shimano Tiagra disc brakes are brilliantly reliable and handle the stopping duties with minimum effort
- Continental’s Grand Sport Race in 32c, hitting the sweet spot for grip, cornering and low rolling resistance
