Available with Cube in the sizes shown above. Expect delivery within 8-9 working days of placing an order.

Fast is light, fast is efficient, but above all fast means zero compromise. The AMS ZERO99 C:68× 29’s frame is crafted from our premium carbon and weighs in at a stunning 1,600g, 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 110mm 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.

That podium result just moved a little closer. With its C:68X® carbon frame and carefully curated components, the AMS ZERO99 C:68X Race 29 sets the standard for cross-country speed. There’s a Fox 34 Float Performance SC fork up front, with 110mm of precise-steering travel. It’s matched to a Fox Float SL Performance shock at the rear.

We selected Shimano’s ultra-reliable XT 1×12 gears because, well, they’re ultra reliable. And added matching Shimano XT hydraulic disc brakes for good measure. And Newmen Beskar 30 wheels shod with Schwalbe Racing Ray/Ralph 2.35in tyres serve up stacks of grip and rapid accelertaion. Topped off with a Fox Transfer dropper post, it’s all you need to find that winning edge out on the race course.
