Pivot Mach 5.5 10th Anniversary


The Mach 5.5 took our market by storm. With 140mm of rear wheel travel, 160mm of burly Fox 36 fork, and just the right size wheels and tires, we knew this thing was going to be a winner. It has become the bike of choice for several GBS Staff rippers, and delivers awesome performance across the board.

Rider Feedback

Pivot has really hit the mark with this bike. It looks like a whole-lot-of-bike given the robust chassis and parts spec, but it rides with a surprisingly light and frisky character. This bike can climb all day without hesitation, but then it’s an absolute blast on the descents. You can tell that this bike was specifically designed to be the one-bike quiver for the modern trail rider. Truly a well-executed design across the board.
