  • Vitus Substance SRS-2 Adventure Road Bike

    Ready to tame any terrain, the Substance SRS-2 gives you a controlled and agile ride even over the roughest ground. Its high-quality steel frame is paired with a UD carbon fibre fork. That’s not the only stand out feature, as it has Shimano GRX 2x11 gravel bike gearing, disc brakes, tough Prime Kanza wheels and wide WTB multi-terrain tyres.

    Adventure Bike with a Reynolds Steel Frame

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

    Shimano GRX Gravel Bike Groupset

    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 VRS-2 is fitted with Shimano’s 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.

    Wide, High-Grip WTB Gravel Tyres

    The Substance SRS-2 is fitted with WTB SpeedTerra 650b TCS wheels, with big volume WTB Venture TCS 47mm tyres. 650b is perfect for adventure cycling with the large outer diameter keeping 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 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 SRS-2 featuring a 16-degree bar flare.

    Easy Assembly

    When you order a bike, one of our trained mechanics will carefully prepare and pack your bike for shipping. Upon delivery, the assembly is simple and all necessary tools are conveniently included in the box.

    Depending on the delivery service and destination, bikes will either be delivered in a large or a small box. Below is a guide as to how your bike will arrive:

    • All bikes for delivery within the UK and Republic of Ireland will be delivered in a large box, except for kids’ bikes and BMX bikes, which are always delivered in manufacturer’s boxes.
    • All bikes for delivery within the EU on a standard service will be delivered in a large box. If an express delivery option is chosen, your bike will be packed into a small box. Again, the exception is kids’ bikes and BMX bikes, which are always delivered in manufacturer’s boxes.
    • All bikes for worldwide delivery outside the EU will be delivered in small boxes.
