The original Mach 429 received the MTBR.com award for best 29er & Mountain Bike Action readers picked it as the 1 choice for their next 29er. The combination of Pivot design & dw-link® suspension makes for a bike that accelerates, descends, climbs, & corners unlike any other 29er made- & now it just got better! Therefore you will be happy to hear the New Mach 429 is both lighter & stiffer. The frame lost over ½ pound in the process of redsign, resulting in the Mach 429 being an efficient riding 29er full suspension frame & super lightest!
