Whether you're at the pump track or your local dirt jump hangout, the last thing you need is to be worrying about your frame. That's why, with the Flying Circus, we applied all our aluminium frame-building know-how to make a chassis that's stiff, strong and perfectly balanced. A BSA threaded bottom bracket gives you a wide choice of crank options, while the jump-specific geometry with super-short chainstays puts you firmly in control.

Races don't win themselves, but the right tool for the job helps. With its premium C:68X® carbon construction, a geometry designed for agility and pace, and carefully curated components, the AMS ZERO99 C:68X 29 will help put you out in front.

Features

• C:68X® Carbon Fiber Technology: Combining all our expertise from carbon frame building into the ultimate material, C:68X® carbon uses the optimum blend of fibre and nano particle-infused resin. Precision Advanced Twin Mold manufacturing means we can avoid bonded sleeves or inserts, too. It's the new benchmark for light, stiff and strong.
• FSP4Link: Suspension kinematics is vital to your bike's performance. At CUBE we use the FSP 4-Link for all our full suspension bikes, with a chainstay pivot and four bar suspension design. It's a proven method for creating active rear wheel travel independent of pedalling or braking forces. We carefully refine pivot placement for each bike depending on its intended use, so you can be sure of outstanding suspension performance on the trail.
• Adjustable headset angle: When you're harnessing gravity, the trail is challenging and every second counts, the geometry of your CUBE is a critical component. That's why our adjustable headset allows you to tweak head angle, so you can set your bike up just the way you like it. A little slacker for more stability, or a little steeper for better agility. The choice is yours...
• Universal Derailleur Hanger: One standard for all: gear hanger replacement made easy thanks to the innovative Universal Derailleur Hanger. With a design that includes some room for pivoting to help prevent chain jams, it improves shifting performance and works with all drivetrains. Best of all, it's a standard part that is available anywhere.
• Advanced Twin Mold: With our Advanced Twin Mold process we use two precisely manufactured forms for our C:62®, C:68® and C:68X® carbon frames. The first form is to ensure an accurate layup. The second, inner form keeps every individual fibre precisely where it needs to be while the frame cures. The result is a significantly lighter, stronger frame, with fibre density tailored to anticipated loadings at specific points.
