2020 Pivot Mach 4 SL 29 XT Race


Regular price $5,199.00 Save $0.00

The Mach 4 SL engineers have pushed the boundaries in every conceivable metric of cross country performance. It's the lightest, fastest 100mm travel XC race bike Pivot has ever developed.  Starting at 1845 grams, the Mach 4 SL is ultralight with full suspension. The new Mach 4SL is over 300 grams lighter than its predecessor, the Mach 429 SL! Optimized tube shapes, a more compact frame design, exotic hi-mod materials, and a dual upright, reinforced swingarm push strength and stiffness while allowing weight to be shaved everywhere.
