JEKYLL GEOMETRY ADJUSTMENT
The adjustable geometry of the Jekyll frame allows for a maximum head
tube angle of 71 degrees with a corresponding bottom bracket height of
13.5 inches (34.3cm) with the shock threaded fully aft in the pivoting
collar. At the other end of the range of adjustment, the minimum head
tube angle is 69.5 degrees with a corresponding bottom bracket height
of 12.9 inches (32.8cm) with the shock threaded fully forward in the
collar. To most easily adjust the geometry, use the following procedure.
1. Loosen the lockring on the shock body, located just in front of the
frame’s pivoting collar, by turning it counter-clockwise (when viewed
from the front of the bike) using a Park red pin spanner tool.
2. Unscrew and remove the bolt which connects the rear of the shock
to the rear swingarm. This will require a 10mm open or closed end
wrench and a 5mm hex wrench. Once the bolt is removed, pivot the
swingarm down and the rear of the shock up so that the two don’t touch.
3. Spin the shock body clockwise (when viewed from the front of the
bike) within the pivoting collar to steepen the angles and raise the bot-
tom bracket simultaneously, or spin the shock body counter-clockwise
to slacken the angles and lower the bottom bracket simultaneously. You
must position the blue compression lever on Fox FLOAT RC shocks in line
with the shock body to most easily adjust the shock position.
4.Once the shock position is set, align the bolt holes in the rear shock
mount and the swingarm, and reinstall the shock mounting bolt. Using
the 10mm open or closed ended wrench and the 5mm hex wrench,
tighten the shock mounting bolt to 106 In-Lbs (12 Nm).
5. Once the shock is set to the desired position and the swingarm has
been reattached, secure the shock in place by tightening the lock ring
against the pivoting collar using a Park red pin spanner. Tighten the lock
ring firmly to prevent the shock from migrating in the collar’s threads.
