A Titanium Hardtail Moutain Bike. Modern trail geometry made to make you smile.

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.

Front and rear centres are scaled across the sizes in order to provide the same ride and handling characteristics across a range of rider heights.

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 are the rear suspension.

Effective seat tube angles across all sizes are 75.75 degrees relative to stack.

Geometric Wizardry


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.
