The CHRISTINI AWD consists of a patented lightweight, inter-
nalized, shaft-driven system that allows the rider to engage
both wheels for additional power when there is "wheel slip".
With the simple flip of a handlebar-mounted switch, the AWD
system provides increased control, traction and stability on
slippery or loose surfaces and unmatched power to climb
steep hills.
Simply stated, when the rear wheel slips — the front wheel
grips.

• Remove the front wheel. The fork legs may
need to be pulled apart slightly, since there is
a 1 mm indent on the non-disc brake side of
the front hub axle. This indent locates the
front bevel gear and provides support during
heavy AWD loading.
• Remove the front disk brake cable at the
lever—or remove the front disk brake caliper.
• Remove the three M6 bolts, located just
above the headtube on the front plate, that
attach the steering link to the upper steering
clamp.
• Warning—DO NOT use the rounded Bohndus
end of the Allen wrench when first loosening
the bolts. You will strip the hex head of these
bolts.
• After these three bolts have been removed,
the fork can be pushed down out of the head-
tube of the bicycle. If necessary, use a plastic
hammer to tap the fork out. Hit the hammer
on the top of the brake arch to avoid damag-
ing the forks valves.
• Please refer to the White Brother’s AWD Fork
Owner’s Manual to service or adjust the front
suspension. (If lost see www.WhiteBros.com
for details)
Installation:
• Slide Lower steering tube into the support bear-
ings in the headtube.
• Tap the fork into place with a plastic hammer.
Do not tap the crown cover.

Fork Driveshaft Maintenance
Removal
• Remove the four countersunk M4 screws under the
crown of fork which hold the crown cover plate in
place.
• Remove the Crown-Cover plate. Slide the Upper
Front driveshaft and the crown cover plate down, as
shown, towards the dropouts. The Upper Front
Driveshaft will compress and slide on the splined
portion of the drive shaft.
▪Remove the fork drive shaft capture bolt. It is an M6 bolt
on the end of the fork drive shaft located under the pinion gear.
▪To loosen the bolt, use the supplied short-end 4mm Allen
wrench to hold the bolt in position while turning the hex piece
of the driveshaft counterclockwise (from the top of the fork
looking down), with a 10mm box wrench.
▪TIP: If the driveshaft is stuck in the gear, loosen the bolt
halfway and then gently tap the blot head with a hammer to
free the driveshaft.

Fork Driveshaft Maintenance
Installation:
▪Insert the drive shaft into the steering tube, sprocket first,
until the miter gear is fully seated on its sealed bearing
support.
▪Loop the chain around the shaft sprocket and the floating
cog. Press the cog into the bearing.
▪Press the upper hex portion of the driveshaft into the cog
and slide the chain crown up into place.
▪Use removable threadlocker when re-installing the crown
cover screws.
▪Use removable threadlocker on the pinion bolt.
Removal:
▪Slide the two sections of the front drive shaft together.
▪The chain crown cover can slide off at this point.
▪The pinion gear can also be removed at this point.
▪Remove the floating cog and power transfer chain from
the internal section of the chain crown.
▪Use your thumbs to press the center sprocket up through
the lower steering tube.
▪Carefully pull the drive shaft out of the steering tube.

AWD Frame Drive-system Maintenance
Re-assembly:
▪Slide the rear pinion into the slot and then drop the rear
drive shaft down into the female spline on the pinion.
▪Apply removable threadlocker to the M6 bolt and tighten
by holding the bolt with a wrench and then spin the drive
system clockwise to tighten.
▪Install the rear shock mount bolt and the rear shock.
Removal:
▪Remove the M6 capture bolt from the rear pinion assembly on
the rear bevel dropout. Use the supplied short-end Allen Wrench to
hold the bolt while spinning the drive system by hand to remove the
bolt.
▪If necessary, use a 10mm wrench to spin the square spline
section of the drive system to help loosen the bolt.
▪Remove the rear shock mount bolt, and then slide the shock
out from between the Top Yoke, as shown.
▪TIP: Be careful not to chip the frame paint with the suspension
link when the rear triangle swings backward.
