The Cube Reaction TM One in rawmetal’n’blue is the hardcore hardtail that bridges the gap between a standard XC bike and a full-on enduro machine. The "rawmetal" finish is industrial and striking, showcasing the beauty of the heat-treated 6061 aluminum frame with subtle blue accents. Built around Cube’s Trail Motion (TM) geometry, this bike features a slack 65 degree head angle and a long, low stance that inspires massive confidence on steep, technical descents where traditional hardtails might feel twitchy.
This 2026 edition has been fully updated with the Shimano CUES 1x11 drivetrain, utilizing Linkglide technology to withstand the higher torque of aggressive trail riding. To match its rowdy intentions, Cube has equipped it with a beefy 140mm SR Suntour XCR34 Air fork and a powerful Magura MT Thirty braking system with a massive 203mm rotor up front. With an included dropper post and a high-traction Schwalbe tire combination, the Reaction TM One is a "point-and-shoot" trail bike that proves you don't need rear suspension to have serious fun in the woods.

Key Highlights
Trail Motion Geometry: Unlike the standard Reaction models, the TM features a significantly slacker head angle and shorter chainstays. This shift in geometry prioritizes stability and maneuverability on "rowdy" trails rather than pure XC climbing efficiency.
140mm Air Suspension: The SR Suntour XCR34 is a "trail-weight" fork with 34mm stanchions for added stiffness. Because it is air-sprung, you can tune the sag perfectly to your riding style, and the 140mm travel allows for much bigger hits and drops.
Magura MT Thirty Stopping Power: Choosing Magura brakes with a 4-piston front caliper and a 203mm rotor is a clear signal of this bike's intent. It provides more raw stopping power than almost any other hardtail in its class, essential for steep, sustained descents.
The "Gravity" Tire Duo: The Magic Mary (front) and Big Betty (rear) are legendary in the downhill world. By fitting these in 2.4" widths as standard, Cube ensures you have maximum "mechanical grip" on loose dirt, roots, and rocks right out of the box.
