New Bike Day: Niner AIR 9 3-Star Single-Speed Build
Niner AIR 9 3-Star
This bike blends the agility and efficiency of a pedal-friendly XC bike with the versatility, toughness and capability of a rowdy trail rig. New for 2021 is the three-star Shimano SLX Single Speed build. Light, simple, quiet and efficient, it’s a whole new way to have fun in the forest. —$2000
Mountain Bike Action is a monthly magazine devoted to all things mountain biking (yes, that’s 12 times a year because we never take a month off of mountain biking). It has been around since 1986 and we’re still having fun.
