The Mach 4 was the first bike Pivot Cycles introduced when Chris Cocalis launched the company back in 2007. Now in its fourth generation, the Mach 4 sheds 26in wheels for 27.5in hoops and gets a new carbon frame design.
The Mach 4 bridges the gap between cross-country and trail, offering the rider 115mm of rear wheel travel paired with a 120mm suspension fork.

Like all Pivots, the Mach 4 uses the dw-link suspension. Cocalis made a point of including a sag meter on the Fox CTD shock that lists the sag points for a firmer, cross-country suspension feel, as well as a softer, more trail-oriented ride.
The Mach 4 features full length internal cable routing. The frame uses a cable port system that is also compatible with Shimano Di2. As such, Pivot also saw fit to design a Di2 battery port into the frame. A plate on the bottom of the downtube houses the Di2 battery. This port also aids in feeding the line for an internally routed seatpost through the frame.

Pivot prides itself on building bikes that fit large as well as very small riders. Standover clearance on the Mach 4 is incredible low, thanks to the use of a curved top tube and seat tube brace.

Pivot claims its extra-small frame has the lowest stand-over clearance of any 27.5in full-suspension bike currently on the market
A medium Mach 4 frame has a claimed weight of 5.1lb / 2.3kg, making it the lightest full suspension model Pivot has ever produced. The top-end complete bike has a claimed weight of 22lb / 10kg.
Pivot offers the Mach 4 in 11 different kits, ranging from the US$8,999 Shimano XTR Di2 bike to the US$4,999 Shimano XT and SRAM X1 builds. The frame with shock retails for US$2,899.
