Welcome to Wound Up™!
Thank you for purchasing a Wound Up™ carbon fork. You
have in your possession what we believe to be the best
fork you can put on your bicycle. In order to make sure
you get the most out of our fork it is imperative for your
fork to be installed correctly. Wound Up™ recommends
professional installation of your new fork by a trained
bike mechanic at your favorite local bike shop. They
will have likely installed countless forks for customers
and will quickly size up these requirements, have all
the proper equipment, and will also provide a thorough
inspection of the components as well as the installation.
Wound Up™ strongly supports local bike shops and their
certied mechanics. We will reimburse the original owner
of any new Wound Up™ fork purchase that is professionally
installed with a $50 (US) rebate to help cover the cost. See
the Professional Installation Rebate program details on pg.
36.

This weight includes the rider with all gear including,
backpacks, hydration systems, etc.

Intended Use of Fork
Each Wound Up™ fork model is intended to be used for a
specic condition. Road forks are for road bike use only,
tandem forks are for tandem bike use only, cyclocross
forks are for cyclocross bike use only, track forks are for
track bike use only and touring forks are for touring bike
use only. NOTE: Wound Up™ may, upon consultation
with customers, help make specic recommendations
for some forks’ use on another bike type based upon
receiving specic information from the rider and/or bike
shop concerning their needs. Please contact Wound Up™
Composites prior to purchase. Attentive riding is a must
to avoid pot holes, sewer grating, railroad tracks, road or
sidewalk construction and other obstructions that could
catch your front wheel and cause a severe impact to
the fork. Wound Up™ forks are not designed for stunts,
jumping or other overly aggressive riding especially if it
results in a crash. Riding a Wound Up™ fork in a manner
other than its intended use, constitutes misuse, which may
result in property damage, serious injury or death, and will
void all Wound Up™ warranties. If you are unsure which
fork to use, contact your local bike shop or Wound Up™
Composites.

Step 1: Install Crown Race
First, you will need to install the Crown Race onto the
steerer tube. Clean both the steerer tube and race with a
clean rag and isopropyl alcohol to remove any oils left over
from the manufacturing process.
Next, place the Crown Race onto the steerer tube per the
manufacturer’s recommendations.
Finally, hold one leg of the fork with one hand, and grasp
the Crown Race Tool with the other hand, and drive the
race onto the steerer tube until it seats against the crown.
See Figure 1.
IMPORTANT: You will need to use a Crown Race Tool to install this
part. If you do not have one, call your local bike shop for more details/
information. If you need extra help, please consider professional
installation of your fork.
