Build Your M1, Your Way!
Start with the legendary M1 downhill mountain bike frame and bring your dream build to life. With our Frame First Program and 3D Configurator, you choose every detail—from components to finish.
evolution of excellence.
The M1 has 203mm (linear) / 212mm (progressive) of rear travel and is built around a 6-link, high-pivot, 6061-T6 aluminum frame. The M1 is a race-proven winner. Designed for a 279 wheelset, developed, and perfected by our engineers and the INTENSE Factory Racing team on the World Cup circuit to be the fastest downhill bike.

HIGH PIVOT
High-pivot bikes, especially in downhill applications, have proven to provide amazing performance and podiums. The rearward axle path of the M1 moves the rear wheel out of the way of trail obstacles, helping the bike maintain momentum and control. The position of the idler pulley reduces the effects of chain growth, eliminating pedal kickback, and further enhancing suspension and pedaling performance.

ULTIMATE SET-UP
The M1’s 6-Link suspension design offers two shock mount positions, allowing you to choose between Linear and Progressive settings without changing your geometry. The Linear position provides 203mm of travel with a 27% progression rate, while the Progressive setting delivers 212mm of travel with a 31% progression rate.

THREADED BB
The M1 features a threaded bottom bracket, a preferred choice for riders who handle their own bike maintenance. Compared to press-fit systems, threaded BBs are known for their ease of installation, removal, and maintenance, along with a more durable, secure connection. They are also less prone to creaking, making them a reliable and low-maintenance option for long-term performance on demanding terrain.

EASY TO WORK ON
We prioritized easy maintenance in the M1’s design. Key features include externally routed cables, 6mm Hex compatibility for all hardware (except one collet bolt), enduro bearings, and three ‘captured’ washers in the linkage that stay in place during reassembly.

Full Size Head Tube
The full-size 56/56 headtube, with a 63º head angle, allows you to run a 0-10mm reach adjustment headset. These adjustments mean that you can set the bike up to suit your riding style, personal preferences, and track conditions.

Alloy Frame
The M1 is crafted from high-performance 6061 aluminum and features a ZS56/ZS56 headtube, full downtube armor for impact protection, and an integrated mudguard to shield the frame from debris—keeping your shock clean and running smoothly.
