OWNER’S MANUAL

Congratulations and thanks for your purchase of a HeadShok Silk
Road suspension fork. The hydraulic DD15 cartridge in the Silk 
Road fork is designed to give a smooth, comfortable ride by absorb-
ing minor impacts and hand numbing vibrations which cause rider
discomfort and which actually slow the forward momentum of the 
bicycle. You have invested in a light weight suspension system fea-
turing adjustability, absolute steering precision, and an “On-the-Fly”
lock-out for increased efficiency climbing or sprinting. All of this
translates into a faster, more enjoyable ride with less rider fatigue.
This manual contains important and useful information regarding
proper operation, care, and maintenance of your HeadShok Silk Road
fork. Please read and carefully follow these instructions for miles of
safe, high performance riding. If you have any questions about your
fork or the contents of this manual, don’t hesitate to contact us. 
See the back page for phone numbers and E-mail contacts.

Silk Road suspension forks offer 15mm
of travel using a coil spring with a col-
umn of MicroCellular Urethane (MCU)
running through its middle. They also
feature the shim-valved DD15 hydraulic
damper cartridge which controls the
rebound speed of the spring and can 
be locked out “On-The-Fly” by turning
the Damping Dial

TM

, located atop the

handlebar stem (See Fig.1,) And unlike
other suspension forks which slide over
high friction bushings, Silk Road forks
roll inside the head tube on 88 needle
bearings for unsurpassed smoothness of
travel. Lack of static friction (“stiction”)
combines with the damped, dual rate
spring system to be sensitive to both
high frequency road buzz and to minor 
front wheel road impacts.
