CONGRATULATIONS on selecting an RST suspension fork.
You have chosen the best suspension components for your
bicycle! This RST fork is fully assembled and ready to be
installed onto your bicycle.
Proper care and maintenance of your RST product is necessary for longevity and optimum
performance.
Failing to perform routine maintenance will greatly decrease the performance of the
product and may lead to premature deterioration or even failure of the product. Lack of
maintenance may also jeopardize the safe operation of your fork and will void the warranty.
This is an off-road fork, and as such, does not come with proper reectors for on-
road use.
Have your dealer or mechanic install proper reectors to meet the Customer Product
Safety Commission’s (C.P.S.C.) requirements for bicycles if the fork is going to be
used on public roads at any time.
This manual contains important information about the safe operation and maintenance
of your fork. Reading this manual entirely, and properly maintaining your bicycle and
suspension fork is essential. To ensure that your RST fork performs properly, we
recommend that you have your fork installed by a qualied bicycle mechanic. Prior to
riding your bicycle, you should inspect your suspension fork to ensure that no damage
has occurred during the course of riding.
Do not ride your bicycle if the fork shows any signs of bending, cracking, leaking, or
if it is missing any of the original supplied components. Any fall from your bicycle can
result in serious injury or even death. Following these instructions can help you reduce
the risk of being injured. We recommend returning your suspension fork to your dealer
or an authorized service center annually for a thorough inspection and service.
1. Never remove or have the steerer tube or stanchions removed from the crown. The
steerer tube and stanchions (inner legs) are press t at the factory. Press tting of the
inner legs and steerer tubes has higher performance versus having clamped stanchions
or steerer tubes, but they can NOT be pressed out and changed. Pressing them out will
permanently damage the crown beyond repair and render it unsafe for any use.
2. Do NOT attempt to thread a thread-less steerer tube. Cutting threads will weaken the
steerer tube and cause an unsafe condition. The only safe thing to do is to obtain the
proper crown/ steerer from your dealer, contact RST USA warranty service center or
RST Europe.
3. Any other alteration or modication to your fork should be considered unsafe and will
void the warranty. Contact your dealer, RST USA warranty service center or RST Europe
prior to modifying your fork in any way for safety information.
4. Do not use an RST fork if any parts are broken, bent, cracked, or you suspect may be
damaged. Contact your dealer, RST USA warranty service center or RST Europe, if you
have any question concerning the integrity or condition of your fork.
5. RST recommends that you inspect your fork before every ride for wear and damage.
Please pay particular attention to the crown, stanchions, sliders, dropouts and brace for
any sign of cracks, bending or damage.
