Mach 4 SL Pro XT/XTR Bike Information

The Pivot Mach 4 SL is a full suspension cross country bike that can perform at the World Cup level. With cross country evolving to include more and more technical terrain, some riders prefer a bit of extra rear travel. The Mach 4 SL comes with 100mm of rear travel which is perfect for taking the edge off without taking away any speed. This version is equipped with a Fox Factory DPS rear shock. At the front, you will find a Fox Factory Stepcast 34 Fork to add 120mm of front travel. The engineers at Pivot designed the Mach 4 SL while considering every single possible metric of cross country racing and success. You can be sure they left nothing to chance before releasing the carefully thought out Mach 4 SL.

When it comes to cross country riding, keeping the weight to a minimum is imperative. Despite its status as a full suspension machine, the Mach 4 SL manages to stay incredibly lightweight to keep a level playing field with its hardtail counterparts. The new Mach 4 SL is more than 300 grams lighter than its predecessor, the Mach 429. An integrated headset and carbon suspension bearing pockets also shave off grams, keeping the amount of metal on the frame to a minimum. On top of its lightweight nature, the carbon layup of the bike remains incredibly stiff for outstanding power on a speed focused 29 inch machine. The Pivot Mach 4 has one of the best stiffness to weight ratios Pivot has ever created.
