Overview

NEW FOR 2025: Read about the improvements to the v2 Datum here

Designed and manufactured in California, USA; DATUM is a 145mm rear travel All-Mountain / Trail bike, with a 160mm fork.

Its all-new ANALOG suspension matches both the better descending and pedaling attributes of the industry's most respected four-bar suspension systems, while delivering significantly reduced weight, carrying more water bottles, and offering improved reliability.

It does this by replacing the many parts which on other frames comprise the upper link and shock subassembly with a unified strut, named INTEGER. Hidden inside the frame, it guides the upper suspension pivot smoothly and with incredible lateral stiffness, flows more oil, squeezes more air, and has fewer parts in an easily serviceable, low motion-ratio package.

The culmination of years of development and ride testing on trails, bike parks and all-mountain terrain, Datum is our reference, our middle point between XC and DH. It's a mountain bike for riding in, across, up and down mountains - we're not going to call it a quiver-killer, but it's a bike which will deliver miles of smiles whether you're showing up for your local Wednesday Night XC World Championships or Sunday's Shred Session Enduro Series.

Custom Cerakote colors are available from the selection shown below.

I’ll confirm which color you want after your frame has been welded.

Cerakote is a lightweight ceramic finish, it is non-stick, looks amazing, is incredibly durable, and has graphics masked in to show the raw aluminum beneath.
