Pivot’s Mach 429 SL is the 100mm 29er you want for ultimate power transfer efficiency and technical trail mastery. On climbs, you'll benefit from the latest in dw-link suspension design with a Fox Float DPS Kashima Factory shock that's performance-tuned specifically for the Mach 429SL. On the trip back down, the 100mm dw-link suspension performs like a longer travel bike, offering speed-carrying obstacle clearing and a go-fast feel. Add the precision of a 12x148mm rear end and the rollover qualities of 29-inch wheels, and you’ve got the advantage in technical terrain and breakneck-speed descents. The Mach 429SL Frame is the first step toward an XC bike that will elevate your racing and your spirit, all at the same time.
