The all-mountain hardtail category is one comprised of uniquely sim- ple beasts. They’re designed to provide the descending confidence of a slack bike with burly components, but without the maintenance and complexities of a full-suspension design. Often the only bike
in the quiver that always seems ready to go, the all-mountain hardtail is
the bike that can be grabbed without necessarily knowing what trail you’ll
end up on—no need to worry if linkages need maintenance or making
sure proper shock sag is providing optimal performance. Niner’s ROS 9
is designed to deliver all the above in a rip-roaring package that’ll be at
home on any trail.
WHO IS IT MADE FOR?
Certain riders appreciate a complex machine with all the properly
dialed bells and whistles that allow them to reach peak speeds and send
drops so aggressively that they might occasionally be landing in the flat.
Other riders are looking for a bike they’ll feel confident hitting trailside
doubles on, but are willing to take it a little easier in the rock gardens
that fill the gaps. They’ll pass up on leading the pack in exchange for a
simple machine. The Niner is a good-to-go bike for the good-to-go rider.
WHAT IS IT MADE FROM?
All-mountain hardtails seem to be the largest category of bikes built
using steel tubing. Steel provides durability and delivers more forgiving
compliance through rough terrain. The standard-width, 73-millimeter
shell is designed to house a BioCentric II bottom bracket for ultimate
adjustment of bottom bracket height and drop, as well as chainstay
length. While a bash guard is not included, the frame does provide tabs
for a custom MRP XCG bash guard that can be purchased separately.
While neither of these options are utilized on the stock build, we appreciate Niner including stealth routing options for a seatpost, as well as a
front-derailleur direct mount.
