WARNING: A bike and its components sustain the hight levels of reoetitive stresses. The fatigue endurance depends largely on the nature of the materials and their
micrographic structures. If you use a component longer than its standard fatigue like, id risks cracking and then suddenly breaking, causing serious injury or
even death. The apparance of cracks, scratches or discolorations are clues that your bike is fatigued and worn. If you find any of these, immediately ask your
authorized Devinci dealer to evaluate the components and replace them if necessary.
8.1.5 Braking and shifting issues
If you find a problem with your brakes when doing your safety mechanical inspection, try adjusting their strokes by turning their tuning barrel. Make sure you lock it back screwing its lock nut.
If the problem persists, ask your authorized Devinci dealer for assistance.
If you find a shifting problem when doing your safety mechanical inspection, the derailleur is probably maladjusted. The problem may come from a simple elongation of your shifter cable.
Turn the shifter’s tuning barrel counterclockwise a quarter of a turn and lock it back with its lock nut. If the problem persists, ask your authorized Devinci dealer for assistance.
8.1.6 After riding 25 off-road hours or 50 road hours
Bring your bike to your authorized Devinci dealer for a complete check-up.
8.2 Emergency repair
If you ride your bike near your home and a mechanical failure occurs, you could still get back on foot or call a friend to pick you up. However, the situation is not the same if you’re on a long
ride. Here’s why it is essential you bring the following equipment in case of emergency:
• Allen keys (4mm, 5mm and 6mm) to tighten your bike screws;
• A small tire pump or an inflating cartridge compatible with your valve;
• Spare tire tube;
• Tire removing tool;
• Your identity cards;
• Cash to quench your thirst, buy foods or use a phone.
8.2.1 Flat tire
Remove the wheel as shown in section 7.1.1. Press the valve to empty the inner tube completely, referring to section 7.5.2. Start removing the tire from the rim, on the end opposite to the
valve. To do so, press simultaneously on the tire from the interior of the rim and lift the tire by sliding it on the rim or use a tire removing tool to gently lift the edge of the tire over the rim.
Remove the valve lock nut and push the valve through the rim. You can now remove the inner tube.
Inspect the tire carefully to identify and remove, if possible, the object that caused the flat. If the tire is cut, try covering the damaged area to prevent pinching the inner tube. Use tape, a spare
patch, a piece of the old inner tube, a piece of paper or anything similar that could temporarily do.
Install a patch on the inner tube as shown in the patch installation manual or even better, change the inner tube for a new one.
Place the inner tube inside the tire and place the tube valve in the rim hole. Do not tighten the nut yet. Inflate the tube slightly and insert the tire on the rim with your thumbs, starting at the
valve. Avoid pinching the tube between the rim and the tire. If you are not able to insert the last few centimeters of tire, use a tire removing tool very carefully, trying not to pinch the tube.
WARNING: The installation of a patch on your tire’s inner tube is an emergency and temporary repair. The use of a patch may weaken the tire considerably and cause a
puncture that could result in loss of control and a fall. Replace the partched tube with a new one as soon as possible.
WARNING: You risk piercing the tube if you try installing your tire with a screwdriver or any other tool not intended for this use.
Check with your hands that the tire is properly centered with respect to the rim and that the tube is well-positioned. Inflate the tube to the recommended pressure by referring to section 5.4.2.
Tighten the valve lock nut with your hands and install your wheel back on your bike.
WARNING: Never ride with a flat or deflated tire. You risk damaging the tire, the wheel and the bike, and could also lose control and fall.
8.2.2 Broken spoke
When one of your wheel’s spokes becomes broken or loosened, your wheel is weakened. If you break a spoke during a ride, get back to your starting point really slowly and safely since you
risk breaking others and irreversibly damaging the wheel.
WARNING: A broken spoke weakens the wheel considerably. This could make it wobble and rub against the brake pads or the frame. You would therefore risk losing control
and falling.
When you have a broken spoke, twist it around its closest neighbor in order to avoid jamming between the wheel and the frame. Lift the wheel and turn it to make sure it turns safely and that
the wheel does not touch the brake pads. If the wheel touches the brake pads, then you need to walk your bike to your starting point. It is very dangerous to ride with a wobbling wheel that
has a broken spoke. Have your authorized Devinci dealer repair or change your wheel as soon as possible.
8.2.3 Accident or major impact
First make sure you are not seriously hurt.
WARNING: An accident may prematurely wear the different parts of your bike, therefore causing unexpected failures that could cause injury or even death.
CAUTION: Bring your bike to your authorized Devinci dealer after an accident or a serious fall for a complete inspection.
After an accident, inspect your bike carefully and repair everything that you can. Do not hesitate to contact your authorized Devinci dealer for assistance in the process. Once back at your
starting point, proceed to the detailed mechanical check-up described in section 5.4 in order to identify every damaged part. Replace every part which has been bended, deeply scratched or
discolored.

Carbon fi ber has been put to the test in recent years and has yielded excellent results. It has very different properties than aluminum. Unlike aluminum, carbon fi ber is not subject to fatigue,
does not deform, does not bend or dent: it breaks. Damaged carbon fi ber components may not appear compromised or dangerous but can be subject to sudden failure as result of impact,
and may do so without warning. DEVINCI would like you to enjoy safe rides. If you crash or your bicycle has sufered a major impact, have an authorized DEVINCI dealer inspect your bicycle.
WARNING : A damaged carbon fi ber frame may fail under impact and cause an accident leading to serious injury or even death. A crash or impact may result in damaged
carbon fiber. If you suspect damage to your carbon fi ber frame or components due to crash or impact, bring your bicycle immediately to an authorized DEVINCI
dealer for inspection. DO NOT CONTINUE TO RIDE!
10.1 Inspection
Inspect regularly your frame and components using your eyes, ears and hands. If you suspect an anormaly, cease riding immediately and bring it to an authorized DEVINCI dealer for
inspection.
