For the break-in period Foes recommends that you introduce a low pressure,
like 65 psi, to start. This is a good setting to break-in your shock, and will
allow you to get a good feel for what this pressure will do over a variety of
terrain. Your Curnutt will break-in properly in about 10 hours of ‘normal’ riding.
This means that, much like a new motor, the contact-moving surfaces of the
shock will ‘seat’ better if they are allowed to move throughout their entire
range or stroke, without introducing them to undue or violent spikes of energy
(as in landing from jumps). Once your shock has broken-in, you will be able
to much more accurately feel what the shock is doing with more or less air
pressure. Adjusting air pressure during the break-in period will be confusing
at best. That being said, if your shock repeatedly bottoms over normal trail
terrain during break-in, it is appropriate to introduce more air pressure to
compensate – 5 psi at a time. Additionally, it should be remembered that
proper break-in requires the shock to cycle through its entire stroke or travel.
If it appears that your shock is not using its entire stroke (too stiff) – over
normal riding conditions - then reducing its air pressure would be an appro-
priate measure – BUT NEVER GO UNDER 50 PSI!. Once your Curnutt XTD
is broken-in, controlling bottoming with proper air pressure and the Ramping
Dial will be more accurately achieved.
BREAK-IN PERIOD
Since your Curnutt was actually built, valved, sprung and pre-loaded accord-
ing to your specific rider weight, skill level and type of riding you mostly enjoy,
your Curnutt shock is about 95% tuned to you right from the factory. The
other 5% will be the Bottoming Control, and tuning your Rebound Damping.
The ‘BOTTOMING CONTROL’ section on page 11 will address Bottoming
Control and the air pressure that affects it. (If you have an AIR shock, please
see its addendum.) Rebound Damping will be addressed in a following
section. Your Curnutt XTD Shock is a true fluid–damped, coil-over shock
which, uniquely, uses air pressure to control bottoming (as well as reduce
fluid foaming). The range of air pressure needed inside your Curnutt XTD is
between 65 and 100 psi. This means, between these minimum and maxi-
mum pressures lies an ideal setting for the control of bottoming the rear
suspension over a given terrain. As said initially, your shock’s compression
damping is mostly set for you at the factory, yet, adjusting the air pressure will
tune your shock’s ability to resist bottoming – an important feature for the life
and longevity of your Curnutt Shock and Foes Frame.

riding with heavy loads, commercial activities, and other types of non-
standard use can dramatically shorten the useful life of the Foes Frame or
Fork. Any one or a combination of these factors and conditions may result in
an unpredictable failure of a Foes Frame or Fork that would not be covered
by warranty. ALL FOES FRAMES, FORKS, AND SHOCKS SHOULD BE
PERIODICALLY CHECKED BY A RETAIL OUTLET OR A FOES DEALER
for indicators of stress and/or potential failure, including cracks, deformation,
corrosion, paint peeling, dents, and any other indicators of potential prob-
lems. These are important safety checks, and may be very important to help
prevent accidents, bodily injury to the rider, and a shortened life of the Foes
frameset or fork. THIS IS AN INTEGRATED AND FINAL STATEMENT OF
THE FOES LIMITED WARRANTY. FOES DOES NOT AUTHORIZE OR
ALLOW ANYONE, INCLUDING FOES DEALERS OR RETAIL BICYCLE
OUTLETS, TO EXTEND ANY OTHER WARRANTIES, EXPRESSED OR
IMPLIED, FOR FOES. NO OTHER REPRESENTATION, AND NO STATE-
MENT FROM ANYONE BUT FOES, INCLUDING A DEMONSTRATION OF
ANY KIND BY ANYONE SHALL CREATE ANY WARRANTY REGARDING
THIS FRAME OR FORK. ALL OF THE REMEDIES AVAILABLE TO THE
ORIGINAL OWNER ARE STATED HEREIN. IT IS AGREED THAT FOES
LIABILITY UNDER THIS LIMITED WARRANTY SHALL BE NO GREATER
THAN THE ORIGINAL PURCHASE PRICE AND IN NO EVENT SHALL
FOES BE LIABLE FOR INCIDENTAL OR CONSEQUENTIAL DAM-
AGES.
All other remedies, obligations, liabilities, rights, or warranties, expressed or
implied, arising from law or otherwise including, but not limited to, any
claimed implied warranty of merchantability, any claimed implied warranty
arising from course of performance, course of dealing or usage of trade, and
any claimed implied warranty of fitness, are disclaimed by Foes and waived
by the original owner. Some states, jurisdictions, countries, and provinces
do not allow some or all of the limitations set herein or the exclusion or limita-
tion of incidental or consequential damages. If any provision is found
enforceable, only that provision shall be stricken and all others shall apply.
This limited warranty does not provide the original owner with certain legal
rights and recourse, and the original owner may possess other rights or
recourse, depending on the state, jurisdiction, country or province.
WARNING: BICYCLE RIDING MAY BE HAZARDOUS TO YOUR
HEALTH, AND EVEN FATAL! ALWAYS WEAR A HELMET AND PROPER
PROTECTIVE CLOTHING.
