Pivot Mach 4 Carbon Goes 27.5, Remains an XC Trail Weapon

Pivot Mach 4 Carbon

Pivot Cycles was one of the first companies to adopt the DW-Link suspension design. Since 2007, they have utilized the famed short-link platform and the Mach 4 was the first bike in the stable. Now, the 4th-generation Mach 4 takes things up a notch in every possible way.

For starters, the new Mach 4 sizes up to 27.5 wheels for the Goldilocks of performance. The mid-size wheels roll over terrain while spinning up a little faster than 29-inch wheels. Shorter riders will especially appreciate the mid-size wheels or those who prefer the most nimble, responsive bike available.

That said, the Mach 4 features ultra-short 16.8″ chainstays that are pared to a 68.2-degree head angle (w/120mm fork) — making for a whippy handling bike with enough chutzpah to tackle more technical terrain than a 115mm travel bike should.

Pivot specs the Mach 4 with either a 100 or 120mm travel fork and can be had in nearly every available groupset under the sun in four color combinations. I’d say the Mach 4 is particularly well-suited to women and smaller riders who will appreciate the lightweight platform and the ‘tweener wheels.

If you’re so inclined, the new Shimano Di2 drivetrains will find one of the most catered homes with the Mach 4. The built-in battery port in the downtube offers a clean, integrated look. No detail was overlooked with the all-new Mach 4.

  • 27.5″ wheels for the best of both worlds

The Bottom Line

The new Mach 4 is the lightest full-suspension frame that Pivot has ever made. It’s available in just about every build combination and can span the spectrum of XC and trail performance. Your legs just got a boost and those KOM’s may now be in reach — thanks to Chris Cocalis and his crew.
