*All measurements in mm. Match your measurements to guide your bike size. If unsure, hit the green Contact Us button.

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

The seat tubes are short to accommodate the latest generation of long travel dropper posts (170 mm - 210 mm). 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 the stack.

What’s the turnaround time for a DownRock? If ordering a frameset only, and the required size is in stock, you should receive your order within 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.
