Rondo Ruut ST 2 Gravel Bike 2021
With a classic steel frame, rugged build and accurate components, the Rondo Ruut ST 2 Gravel Bike gives a versatile performance whether charging across the wilderness at the weekend or completing the daily commute.
The Tange Champion steel frame is tough and resilient and naturally infuses large amounts of comfort into any ride. The partnering carbon fork is light, vibration absorbing and laterally stiff and features TwinTip technology that allows its offset and length to be changed, tuning the handling in line with the terrain ahead.
Luggage rack mounts mean that the bike can be loaded up for long trips and mudguard attachments ensure that full protection from the elements is possible when the weather turns foul. Rondo alloy wheels are light but robust and can be fitted with broader tyres when tackling rougher riding surfaces thanks to the frameset’s generous amounts of clearance.
A SRAM Apex 1 drivetrain is reliable and precise and boasts a wide range of gears while the TRP mechanical disc brakes give consistent stopping power in all conditions and offer easy maintenance.
