Pedigree counts in racing. That's why we chose a RockShox SID SL Ultimate fork for the AMS ZERO99 C:68X SLT 29, delivering 110mm of ground-hugging travel. We matched it with a RockShox SIDLuxe Ultimate shock at the rear, and added Newmen Phase 30 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.
