Summary

The Pivot Mach 55 is a versatile trail bike that excels in technical descents and offers a comfortable ride for long trail adventures. Its DW-Link rear suspension is praised for being active and sensitive, providing excellent small bump compliance and mid-stroke plushness. However, some reviews note that the bike's extra-active suspension can be an energy drain on climbs, and its high cost of entry may deter some riders.

Pros
  • Rear-suspension sensitivity and suppleness

  • Active and linear-feeling DW-Link suspension

  • Comfortable for long trail adventures

  • Versatile performance in technical descents and climbs

  • High-quality components and build

Cons
  • Extra-active suspension can be an energy drain on climbs

  • High cost of entry

  • Rear tyre lacks grip in some conditions

  • Live Valve system may seem unnecessary to some

Pivot now offers the The Pivot Mach 5.5 with the brand new FOX Live Valve system. But does the bike need FOX’s high-end electronic suspension?

  • Excellent rear linkage

Lows
  • Rear tyre lacks grip

  • A little sluggish in acceleration

  • Not made for rough, high-speed terrain

PIVOT MACH 5.5 Words & Photos by Andrew Lee Pivot bills the Mach 5.5 as a Plus-tired do it all machine, but as skeptics, we’re tired of hearing every brand’s bold claims about the ultimate all around performing bike. Despite our skepticism, we have spent lots of time

The Pivot Mach 5.5 is almost an enduro bike, has the essence of an XC bike, looks plus-sized, but remains lithe.
