Enter the DownRock - our interpretation of the modern trail hardtail. A balanced, versatile mountain bike for fanging around like a frill neck lizard on hot sand.
The Downrock brings back that raw, adrenaline rush - it whips around corners faster than a tiger snake and will leave a big dumb grin on your face.
The seat tubes are short in order to accommodate the latest generation of long travel dropper posts (170mm - 210mm). This is especially advantageous on a hardtail as your legs act as the rear suspension.
Bottle cage mounts are placed low inside the front triangle and underneath the downtube to maintain the lowest possible centre of gravity and to give room in the front triangle for a frame bag if required.
Front and rear centres are scaled proportionally across the sizes in order to provide the same ride and handling characteristics across a range of rider heights. This is especially important for riders with longer inseams as it prevents the saddle sitting too far behind above the rear wheel.

|What’s the turnaround time for an DownRock?||If ordering a frameset only, and the required size is in stock, you should receive your order with 2–3 weeks. If the size you need is out of stock, or if you have ordered any custom modifications, the frame will take an additional 6–12 weeks to go through production. Complete bikes generally take 8–12 weeks to build after a minimum 50% deposit has been paid.
