The Vitus Substance loads your ride with freedom and choice. It expands your world, opening up new possibilities to ride and explore where otherwise you might not have looked. Unshackled from the same old routes, each ride reveals new ways ahead, like a fresh map - that bridleway to who-knows-where, the gravel track through the woods or the rougher shortcut that you know is quicker but that other bikes couldn’t handle.

See, in a world obsessed with pace, sometimes we need to focus on the place, the journey and the fun that comes from a bike with the capability to seek out adventures where others wouldn’t.

Whether embarking on a far-flung bikepacking adventure or simply staying light for a mixed-terrain local loop, the Substance with Shimano GRX components is capable of adapting to suit your ride. At its core, a double-butted aluminium frame and carbon fork are tuned for comfort on long days and across varied surfaces, aided by big volume tyres that soften the bumps and add traction over rutted or loose tracks. With compatibility for 1X or 2X drivetrains and either 700c or 650b wheels, you can really fine-tune the setup to best fit where you are riding. And if ultra-racing or multi-day expeditions are your thing, the frame has mounts for luggage, waterbottles and mudguards. For those remote rides where water, food and spares might be hard to come by, you can always load up with whatever you need to reach the next supply point.

This isn’t simply about the same cliches of getting off the beaten track or going in search of the road less travelled, because the Substance is more than a gravel or adventure bike. It broadens your horizons, delivering richer experiences and powerful lasting memories. It’s a bike that enables you to do more. It’s a bike that gives you options. The Substance empowers a new mindset, one that entices you to break away from routine and to ride where you want to ride, unrestricted.

Great quality
Color: Four colors, Size: 5cm (ball only)
I was very surprised that these are as good as the chuck it balls. I have a super chewer and he’s tears balls up except for chuck its and he can’t tear these up.

Awesome price for quality balls
Color: Four colors, Size: 5cm (ball only)
These balls are super bouncy and durable. My dog loves them and for the price these are totally worth it! I think they are as durable as nerf balls and equal in size, and much cheaper!

Rope comes out at the slightest force. Pointless tug toy!
Color: Four colors, Size: 6cm (with rope)
If your dog pulls on these (and why wouldn’t he?), the rope immediately comes out. Turns out they just fuse the ends of the nylon rope together, which is no match for a dog playing tug. Any dog, any level of pulling will dismantle these. We’ve managed to reinsert the rope to a couple of these and KNOT it, which gives you a shorter rope but a toy that can withstand some play. But if I had wanted a DIY toy, I’d have used the balls and rope I already own.
