of about 10cm/4” to ensure that there are no loose parts. Riding with an improperly adjusted
wheel quick release can allow the wheel to wobble or fall off the bicycle causing injury or
death.
• Before riding, verify that the brakes on your bicycle are installed and adjusted correctly. Improp-
erly installed and adjusted brakes may cause a crash and result in property damage, serious
injury, or death.
• Make sure cables and hoses do not impede the steering of the bicycle.
• If mounting the bicycle in a rack designed to hold the fork by its dropouts, avoid tilting the
bicycle to either side. Doing so could cause structural damage to the fork. Be sure the bike is
fastened securely, with the quick-release mechanism tight and the rear wheel properly secured.
If the bicycle ever tilts on, or falls from a bicycle rack, do not ride it until it has been examined
by an authorized dealer, service center, or by FORMULA S.a.s.. A structurally damaged fork leg
or dropout failure can cause a sudden loss of control, resulting in serious injury or death.
• Wet weather impairs traction and braking, making it much more difficult to control the bike.
More attention must be paid while riding in wet conditions in order to avoid accidents.
• THIRTYFIVE forks do not include reflectors for public road use. THIRTYFIVE forks are designed
for use in competitive off-road riding and racing. Proper reflectors meeting the Consumer Prod-
uct Safety Commission’s (CPSC) requirements should be installed if the fork will be used on
public roads.
• Always wear a properly fitted and fastened helmet while riding. Make sure the helmet is ap-
proved in the country of use.
• Learn and comply with the local rules of the road and cycling regulations. Always ride carefully
and responsibly.
• Wear close-fitting clothes that make you easy to see (fluorescent or bright colors).
• If you ride at night, use adequate lights and reflectors that are clean and fitted securely.
THIRTYFIVE FORKS SAFETY GUIDELINES
• The THIRTYFIVE forks produced by FORMULA S.a.s. are designed exclusively for use on two
wheel bicycles. THIRTYFIVE forks should not be used for electric bicycles or tandem (multi-
person) bicycles. Any other use is to be considered hazardous. FORMULA S.a.s. shall not be held
liable for any consequences from improper use.
• If the fork ever loses oil or makes unusual noises, stop riding and have it inspected by FORMULA
S.a.s. or an authorized dealer. Continuing to use a malfunctioning fork can cause a sudden loss
of control, resulting in serious injury or death. Some sounds, such as oil flow, minor clicks, and
spring rattle, are considered normal. When in doubt, consult your local Formula dealer.
• THIRTYFIVE forks have a crown / steerer / upper tube assembly. These parts are pressed to-
gether through a single precision pressing operation. Replacing any of these parts requires a
complete new upper assembly. Never attempt to remove or replace the steerer or upper tubes
independently from the crown. NEVER ATTEMPT TO CUT THREADS INTO THE THREADLESS
STEERER. Modifying the crown / steerer / upper tube assembly can cause loss of control of the
bicycle and serious injury or death.
• Impact, falls, improper or harsh use of the bicycle may compromise the structural integrity of the
forks, significantly reducing their lifespan.
• Have the forks regularly inspected by a qualified mechanic for any cracks, deformation, signs of
fatigue or wear. Use of penetrating fluid or other visual enhancers to locate cracks on parts is
