Rondo Ruut CF 2 2x Disc Gravel Bike 2022
Set up to offer fast and efficient off-road travel, Rondo's Ruut CF 2 2x Disc Gravel Bike is ideal for long rides and fast loops.
The frame and fork afford plenty of compliance without losing efficiency thanks to the 3-point design and carbon construction whilst the TWINTIP fork’s two position axle allows the geometry to be steepened or slackened to suit rider or terrain. There are plenty of mounting points on the bike for bottle cages, luggage and racks so that overnight adventures and multi-day trips are a doddle.
Shimano’s 10-speed GRX groupset is gravel-specific, meaning that it has smaller chainrings and great chain retention for use on bumpy ground. By using a 2x system, the cassette can be smaller with closer ratios for optimum cadence without sacrificing gear range, giving greater efficiency. Fast-rolling and tubeless-ready, Schwalbe’s 40c G-One Allround tyres are a great option for rapid travel on a wide variety of surfaces and won’t feel draggy on tarmac.
Please note, images are for illustration only and are not indicative of the bike’s exact specification.
