Emerging ahead of the pack, we bring you the Dirty Disco Gravel. Like it's CX brother, the Gravel is built around our lightweight frameset, but adds plumper wheels suited to more rugged terrain.
Gravel racing is emerging as the latest thrill in two wheeled endurance events. Taking in dust, mud and dense, ominous gravel. The bikes have to be prepared for the all-terrain onslaught.
Our Dirty Disco Gravel rises to the occasion. Pairing lightweight, lengthy chainstayed frame and fork to Deore wheels, capable of taking proper chunky tyres, allows you to stay in control and remain in comfort. Avid Disc brakes provide all the stopping power you're likely to need, whilst the addition of a flatbar presents a more relaxed riding position.
We've kept the sharp shifting 10 speed SRAM Rival groupset, but thrown a FSA Gossamer crankset into the mix, with its cold forged, rigid crank arms keeping the power transfer at the choicest level.
The Dirty Disco Gravel just compels you to be more adventurous, get stuck in and enjoy the rough stuff that bit more.

All frame size recommendations are approximate. A good fit will also depend on the correct choice of stem length, correct bike set-up for the rider and riding style.
Correct frame size choice can vary greatly with riders' torso length. If you have longer legs and a shorter torso, go for a slightly shorter stem. If you think you are borderline between sizes, and you have longer legs and a shorter torso, go for the smaller frame size. If you have shorter legs and a longer torso, go for the larger frame size to get the extra top tube length.
As the frame sizes increase, so does the length of the head tube. If you are inflexible or perhaps have a history of back problems, consider going for a larger frame size. This will increase the relative height of the handlebars making the position less “extreme”. The larger frame will also have a longer top tube, so you’ll need to compensate for this with a shorter stem.
