Cube AMS Zero99 C:68X SLT 29 2025 Bike

The distinctive liquidlava'n'black paint will draw your eye, but it's the AMS ZERO99 C:68X SLT 29's performance that will keep you coming back for more. From the RockShox suspension to the 12-speed SRAM XX Eagle Transmission and carbon wheels, it's all about making the most of your training and chasing down that podium finish.

Pedigree counts in racing. That's why we chose a RockShox SID SL Ultimate fork for the AMS ZERO99 C:68X SLT 29, delivering 11mm of ground-hugging travel. We matched it with a RockShox SIDLuxe Ultimate shock at the rear, and added Newmen Phase 3 Vonoa wheels with carbon rims and spokes, shod with Schwalbe Racing Ray/Ralph 2.35in tyres for the ultimate in grip. Sram's 12-speed XX SL Eagle Transmission serves up a huge range of ratios with incredible shifting precision, so you'll never miss a gear again, and SRAM Level Ultimate hydraulic disc brakes help you ride faster by allowing later braking. Throw in the Fox Transfer dropper post, and you've all you need for flat-out XC race performance.

Fast is light, fast is efficient, but above all fast means zero compromise. The AMS ZERO99 C:68X 29's frame is crafted from our premium carbon and weighs in at a stunning 1,6g, approximately. There's plenty of room for 2.4in tyres - and that means more grip and more control, even in the toughest conditions. Based on feedback from our XC and European Champion riders, chainstay length is tuned for optimum climbing whilst retaining excellent manoevrability. Slender tubes help keep the ride comfortable, rather than harsh. There are angle adjustment inserts to allow fine-tuning of the head angle. And with 11mm of travel front and a geometry that's tuned for agility and pace, you've got everything you need to get to the head of the pack.

Features

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.

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.

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...

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.

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.
