LEFTY NEGATIVE SPRINGS
Lefty forks come with three different weight
negative springs and degrees of rebound
damping, for riders of different weights and
riding styles. The coil negative spring should
not be confused with the main spring, which
acts to set the stiffness of the fork. The nega-
tive spring acts to control the initial plushness
of the fork by overcoming the resistance of the
main spring. It also acts as a top out spring,
to prevent a harsh stop at the rebound of the
suspension travel. Heavier riders or those
using more preload in the main spring (for a
stiffer ride) will want a heavier negative spring
and more rebound damping. See the following
chart for negative spring information. Your
local dealer can advise you about changing
springs.

FRONT WHEEL REMOVAL

The Lefty front hub uses a self-extracting bolt
to attach the wheel to the Lefty's axle spindle.
The bolt is held into the hub by a cap that is
screwed into the non-disc side of the hub
using a pin spanner tool. The self-extracting
bolt and cap combination is very similar to
that used on CODA Tarantula Competition or
Shimano XTR, Dura Ace, and Ultegra cranks,
except that the Lefty hub cap has left hand
threads. The cap should not be removed; it is
there to hold the axle bolt into the hub. If you
do need to remove the cap to replace the bolt,
be sure to reinstall the cap with a drop of
Loctite 242 (blue) on the cap threads.
Remember that the cap will need to be turned
counter-clockwise to be screwed in.
NOTE: It is not necessary to remove the front
wheel from the Lefty fork to change an inner
tube or tire. Simply remove the tire from the
wheel as you normally would using a tire lever,
making sure to pull the tire off of the non-disc
side of the wheel.
1. Using a 5mm hex wrench, loosen (but don't
remove) both front disc brake caliper bolts.
Pivot the bottom of the brake caliper counter-
clockwise so that the bottom caliper bolt
swings out the back of the Lefty's disc brake
mount. Then drop the top bolt down out of the
Kit Code
disc brake mount. See Fig. 7. The wheel can-
not be removed without first removing the
HD212/GRN brake from the fork.
HD212/BLU
HD212/BLU 2. Using a 5mm hex wrench, unscrew the axle
HD212/RED
bolt that attaches the wheel to the fork's axle
HD212/RED spindle in a counter-clockwise direction. Note
that the bolt is held in the hub by the self-
extracting cap, and will stay attached to the
hub even when the wheel is removed from the
axle spindle. There is no need to remove the
cap from the hub.
3. Pull the wheel off of the axle spindle.
CAUTION: Take care not to drop the fork's axle
spindle on the ground when the wheel is
removed. If the spindle is dented, the axle bolt
may not engage the axle spindle and the fork will
not be usable.

FRONT WHEEL INSTALLATION

1. Make sure that the CODA front disc brake
is not attached to the Lefty disc brake mount.
It is not possible to install the wheel with the
brake installed on the fork. If necessary,
remove the front disc brake caliper from the
fork using a 5mm hex wrench as instructed in
step 1 of the FRONT WHEEL REMOVAL sec-
tion above.
2. Apply a light coat of good quality bicycle
grease to the flat bearing seats on the tapered
axle spindle of the fork. Also smear a little
grease on the axle bolt threads inside the end
of the axle spindle. Take care not to get any
grease on the disc brake or brake rotor
attached to the hub.
