Pedigree counts in racing. That's why, with the AMS ZERO99 C:68X SLT 29, we went for Fox Factory suspension components, to provide 100mm of ground-hugging travel front and rear. Sram's XX1 Eagle AXS 1x12 serves up wireless shifting with unmatched precision, so you'll never miss a gear again. Sram Level Ultimate Rainbow hydraulic disc brakes help keep your speed in check, and ultra-light Schwalbe Aerothan inner tubes ensure every ounce of your effort is translated into forward progress. Newmen carbon components – including a carbon wheelset – provide the finishing touches. The rest is up to you.
Frame description Fast is light, fast is comfortable, and fast is efficient. The AMS ZERO99 C:68X Race 29's frame is crafted from our premium carbon and weighs in at a stunning 1600g, approximately. But it's not just about low weight. Short chainstays with plenty of clearance for 2.25in tyres tuck the rear wheel in under the rider for efficient power transfer. Slender tubes help keep the ride comfortable, rather than harsh. There's an Angle Set to allow fine-tuning of the head angle. And with 100mm of travel front and rear and a geometry that's tuned for agility and pace, you've got everything you need to get to the head of the pack.
Find your size!
Enter your height and inseam below and click on 'Calculate my frame size' to see which size you need. You measure your inseam as follows:
1. Stand barefoot with your heels against the wall. Place your feet about 6 inches apart.
2. Grab a book and place it between your legs, with the short side of the book against the wall. Press the book up against your crotch, mimicking the idea of a bicycle saddle.
3. Measure the length from the top of the book to the floor, the distance you measure is your inseam.
