The Substance is the bike that will go anywhere you point it; on whatever road surface you choose.

With a brand-new Reynolds 725 Heat-Treated Chrome-Moly double butted steel frame from the legendary British tubing manufacturers. Paired to carbon fork designed to take both 700c and 650b wheels & tyres, the possibilities are endless. The Substance offers you a new way to ride.

Featuring a tapered headtube, and full T-700 UD carbon forks, the Substance steel is born tough. This bike is made for round-the-world adventure or dependable and comfortable commuting. With the addition of mounts for mudguards, luggage, and multiple bottles, it?s also capable of going anywhere for any amount of time.

The Substance SRS-2 is fitted with Shimano?s newly released GRX 600 groupset ? the world's first dedicated gravel groupset. Paired with the GRX 810 rear mech, this 11 speed 2X groupset delivers a smooth and quiet drivetrain, specifically tuned for gravel/adventure riding.

The Substance SRS-2 is fitted with WTB SpeedTerra 650b TCS wheels, with big volume WTB Byway TCS 47mm tyres. We believe 650b is the future of adventure cycling, the large outer diameter keeps your wheels rolling over bumps, whilst the added tyre volume allows you to adjust pressures depending on the terrain for grip, comfort, and luggage weight. The Wheels and tyres are tubeless ready, so just install the supplied valves and add sealant if you want to run tubeless.

Finishing kit is made up of a Vitus 6061 aluminium handlebar, stem, and seat post. The handlebars feature a flat top section for added comfort on and off road, with the Substance CRS-2 featuring a 3-degree bar flare. The bike is finished with a Vitus saddle with Ti rails.
