Rondo Ruut AL 1 2X Gravel Bike 2021
With a resilient frame, a carbon fork and reliable components, the Rondo Ruut AL 1 2X Gravel Bike lends a multifaceted performance across varied riding surfaces when tackling longer rides, bikepacking trips or winter training on the road
The aluminium frame is light and responsive to give an urgent ride character but is also strong and resilient to manage the rigours of off-road riding. Comfort is built into the frame by the curved seatstays that add vertical compliance over the roughest of riding surfaces. The frame is partnered by a full carbon fork that naturally dampens impacts and has a TwinTip feature that alters its offset and length to either sharpen the handling or donate a more upright riding position. The frameset is completed with rack and mudguard mounting points to cater to the biggest of adventures in all weather conditions.
The frame and fork provide vast amounts of tyre clearance while Rondo aluminium wheels are light and robust to handle any severity of terrain with aplomb. The Shimano GRX drivetrain features a double chainring and a widely spaced cassette to offer a huge range of gear ratios. Hydraulic disc brakes complete the build with confidence-inspiring stopping power, even in the heaviest rain.
