Rondo Ruut ST 2 Disc Gravel Bike 2022
Enjoy the combination of an elegant steel frame and modern geometry with Rondo’s Ruut ST 2 Disc Gravel Bike.
The Tange Champion steel frame gives a comfortable and responsive ride feel that is ideal for exploring away from smooth tarmac roads and exploring lanes and trails instead. Rondo’s TWINTIP carbon fork offers two axle positions, which steepen or slacken the head tube and change the bike’s handling so that it can be altered to suit the terrain or for personal preference. To complement this versatility, the frame and fork can both accommodate 700c x 45mm or 27.5” x 2.2” tyres so that there is plenty of scope for adding bigger rubber if so desired although the supplied 700c WTB Nanos are a great all round option. As befits a bike made for off-road epics, there are multiple bottle cage / luggage mounting points and fittings for a rack or mudguards too.
SRAM’s Apex 1 groupset brings with it reliable simplicity and quick gear changes across the 11-speed cassette whilst the TRP mechanical disc brakes keep the braking surface out of the dirt for much better consistency of performance.

- Rondo Ruut Tange steel frame with rack and mudguard mounts, multiple bottle cage mounts
