Rondo Ruut ST 1 Disc Gravel Bike 2022
Designed as a go anywhere, do anything kind of bike, the Ruut ST 1 Disc Gravel Bike from Rondo is just as happy out in the countryside as it is helping with the daily commute.
Central to its versatility is the Tange steel frame which imbues the bike with a natural compliance that is supplemented by the curved seatstays for extra comfort. Both the frame and the carbon fork have sufficient clearance for 50mm tyres if using 700c wheels or 2” tyres on 650b rims. The TWINTIP fork also offers two axle positions that alter the head tube angle so that the geometry can be adjusted to better suit personal preference or the bike’s usage. A plethora of bottle cage and luggage mounts provide plenty of carrying capacity and the potential to mount racks or mudguards further increases the bike’s remit.
Rival spec SRAM hydraulic disc brakes and 1x11 drivetrain ensure accurate gear changes and reliable stopping power, with the simplicity of the single ring system cementing the bike’s position as a potential weekday workhorse and weekend toy. Fast-rolling Vittoria Terreno Dry tyres provide easy speed on tarmac whilst still offering enough volume and grip to cope with unsurfaced tracks and trails.
