JEKYLL SEATPOST MOUNTING
The Jekyll will accept any 27.2mm diameter seatpost. The seatpost must
be inserted with at least the recommended minimum insertion into the
seatube. Grease the seatpost clamp bolt threads and tighten it to 70-80
In-Lbs (8-9 Nm.)
IMPORTANT: Make sure that the end of the seatpost will not come into
contact with the rear shock and/or swingarm as the suspension is com-
pressed. To check, first adjust the seatpost height for the bike’s intended
rider. Then compress the rear suspension as far is possible in order to
bottom out the suspension travel. If necessary, cut the bottom of the
seatpost to provide at least 1/2” of clearance between it and the suspen-
sion parts when the suspension is fully compressed. Repeat this check
each time the seat height is readjusted. A good guide is to make sure
that the bottom of the seatpost doesn’t extend out past the bottom of
the seat tube.
WARNING: Use only a 27.2mm diameter seatpost and be sure that
the seatpost is held securely by the seatpost collar. The seatpost collar
clamp bolt must be torqued to 70-80 In-Lbs (8-9 Nm.) Failure to
properly torque the collar could lead to slippage, loss of control and
risk of serious injury or death.
JEKYLL REAR SUSPENSION PRELOAD ADJUSTMENT
All Cannondale Jekyll models use a uniquely designed Fox shock absorb-
er to provide 120mm of plush rear wheel travel for all terrain riding. To
get the best performance from the rear suspension, the preload pressure
in the rear shock should be adjusted to suit the rider’s weight. The Fox
FLOAT R and FLOAT RC shocks use an air spring to adjust the stiffness
of the rear suspension and oil to damp the suspension movement. Before
adjusting air spring preload, clean any dirt from the area around the
Schrader valve on the shock absorber.
If you can’t easily access the Schrader valve to be able to attach a high
pressure suspension pump, loosen the shock lock ring using a Park red
pin spanner tool, place a 13mm wrench on the forward end of the shock
body, and rotate it to an accessible position.
