TRICKS, UPGRADES OR TIPS?
The Nemesis’ 34-tooth chainring is certainly racer-ready, but may be a bit too much gearing for the rest of us.
Thankfully, swapping chainrings on SRAM’s XX1 crankset
doesn’t even require pulling the crankset off of the bike,
and SRAM offers chainrings in two-tooth increments, from
28 to 38 teeth.
Be sure to take advantage of the tubeless capabilities of
the American Classic wheels and Geax tires. Given the
rigid nature of a hardtail cross-country bike, the tubeless
tires go a long way in aiding ride comfort.
At 110-millimeters long, the supplied stem would be
more at home on a road bike. We’d shorten it up by about
20 millimeters and use a bit wider bar for good measure.
While 27.5-inch wheels are quickly becoming the go-to
wheel size for mid-travel trailbikes, there seems to be more
room for debate when it comes to cross-country-specific
For us, it comes down to a couple factors, most notably
riding style and terrain. For riders who miss the lively feel
of 26-inch wheels or are still riding a 26-inch cross-country
bike, the Nemesis will maintain much of the feel they’re
after while providing some of the rolling advantage of the
bigger hoops. Likewise, if your trails require quick accelerations and tight moves through technical terrain, the
nimble and snappy feel of the Nemesis will make you feel
right at home.
While 27.5-inch wheels aren’t the silver bullet for all racing situations, with the demise of 26-inch wheels in cross-country racing, we applaud Jamis for allowing racers to
pick their poison between 27.5- and 29-inch wheels. ❏
Built for speed: The Nemesis’ sleek frame design looks fast
standing still. RockShox’s SID XX fork keeps the front end
light while allowing the riders to remotely lock out the fork. The
internal derailleur cable routing keeps things neat and tidy.

Hold on tight: There’s no denying the Nemesis’ cross-country
intent on the trail; holding it wide open on a descent takes a
skilled pilot with a bit of nerve for good measure.
