owner’s manual contains important and useful information regarding the
proper operation, care, and maintenance of your HeadShok Super Fatty
SL or Fatty SL fork. Please read it carefully and follow its instructions for
miles of safe, high performance riding. If you have any questions about

STEM SELECTION

All HeadShok equipped bicycles come with a CODA

®

Suspension Stem

that is designed to work specifically with the unique head tube arrange-
ment of the HeadShok front suspension system. These stems are sup-
plied in sizes proportional to the different bicycle frame sizes. There are 
a total of 14 different stem sizes available, and all of these stems can 
be inverted, for a total of 28 possible unique rider positions. This allows
any rider to customize the fit of his or her bicycle. See your Authorized
Cannondale Retailer for replacement CODA stems. Framesets and
aftermarket forks do not include a stem.

REQUIRED MAINTENANCE

It is recommended that you take your Super Fatty SL or Fatty SL to your
Authorized HeadShok Service Center for a regular tune up every two
months or 40 hours of riding. Your fork is a high performance suspension
system and needs regular inspection, lubrication, and maintenance. Your
mechanic will check the following items and service the fork as neces-
sary. Between these tune ups, you should also occasionally check the 
top bearing seal and boot as outlined below.
