BIKE TEST / CANNONDALE JEKYLL
Cannondale uses its ECS-TC technology to connect the frame to
the rear triangle. ECS-TC is a series of hollow, 15-millimeter axles
that are used at the contact points between the frame and rear
triangle. This keeps the bike stiff and the overall weight down. The
rear triangle also uses a 12x142 thru-axle.
Not to be overlooked, the DYAD RT2 shock is one of the most

unique parts of the bike.
Cannondale and Fox
collaborated to create
a dual-chamber pull shock
that offers two separate travel
modes for going up and down the
mountain. The Elevate position puts
the bike down to 95 millimeters of
travel for climbing and for smooth-
Flow mode is 160 millimeters of travel and slacks out the bike for
aggressive descents. These modes can be switched at the handle-
bar with the remote lever.
Our test bike came with a mix of SRAM X1
and X01 parts on the drivetrain and Guide RS
brakes, which were the biggest standouts
during our testing. Cannondale did
spec the Carbon 2 with its relatively
new SpideRing—a direct-mount,
narrow-wide chainring that is light
and stiff. We would like to have tried
out the Lefty SuperMax, but the
RockShox Pike gave us all the perfor-
mance we could ask for.
Lean hard: The wide bars gave us plenty of leverage to push hard through corners. With the beefy linkage and stiff rear
triangle, the cornering capabilities of the Jekyll felt endless and of course fun.
Pure enduro: It’s the hottest
term in mountain biking right
now and pushing frame designers
to engineer some pretty incredible
bikes. The Jekyll is light, stiff and,
most important, fast while maintaining a
confident level of stability that trail riders and
racers alike are hunting for.
