Pivot - Mach 4 SL GX/X01 29 - Grey

Cross country racers know that every gram counts. Pivot&';s engineers didn&';t set out to cut a few grams - they insisted on slashing hundreds. Starting at 1845 grams, the Mach 4 SL takes a front row seat in the ultralight full suspension category and has the best stiffness to weight ratios Pivot has ever created. Optimized tube shapes, a more compact frame design, exotic hi-mod materials, and a dual upright, reinforced swingarm push strength and stiffness on this gravity defying cross country rocket ship.
