Before each outing
Action required
Part
You do not need to take the bicycle to an expert if you are skilled, experienced and have the appropriate tools. Immediately
implement the corrective measures if you detect problems. If you are unsure or have queries, please contact BH.
The tasks described above must only be carried out by a trusted bike repair expert.
SPARE PARTS
Original parts must be used to ensure the optimum performance of your bicycle and the utmost safety. Failure to use
original parts may cause damage that is not covered by the warranty.
The most common spare parts are parts prone to wear. The most common ones are tyres, inner tubes, brake pads,
disc brakes and brake pads, as well as rims, when these are part of the brake unit, headlights, position lights,
batteries and accumulators.
•
TYRES: Replace them with an equivalent type of tyre. Check the marking on the outside of the tyre
(ETRTOstandard). Keep in mind that using a tyre with a larger outer diameter than the recommended one may
cause the tip of the foot to touch the front wheel or rear wheel guard when the handlebars turn. The cyclist may
lose control of the bicycle and suffer an accident with serious consequences. This can also occur when the
pedal chainset is replaced with a longer one.
•
INNER TUBES: Replace them with a suitable type of inner tube, according to the type of tyre. Refer to the
information on the outside of the inner tube (ETRTO standard).
•
DISC BRAKES AND BRAKE PADS: Follow the instructions supplied by the manufacturer.
•
HEADLIGHTS AND POSITION LIGHTS: Replace the bulb with one of the same type. Check the indication on the
metal area.
•
CHAIN, COG AND CHAIN RINGS: Follow the instructions supplied by the manufacturer.
•
BATTERIES AND ACCUMULATORS: Change for the same type. Check the indication on the outer area.
Remember that the failure to use original parts may cause damage that is not covered by the warranty.
AFTER A FALL, BLOW OR IMPACT
If you suffer a fall, blow or impact, first make sure that you are okay to continue cycling. Do not use the bike if you
are injured and ask for medical assistance if needed.
If you are okay to continue cycling, check the bicycle to make sure that it is in perfect working order:
•
Check that the wheels are firmly secured and that the rims are in the centre of the frame and fork. Turn the
wheels. If they cannot be centred in situ because the gap is too small, separate the brakes from the rim so itcan
move freely.
In this case, keep in mind that the braking efficacy will be less.
•
Check whether the handlebars or the front of the frame are twisted or broken. Check that the front is firmly
seated on the fork, holding the front wheel firmly between your legs and trying to twist the handlebars with
respect to the front wheel.
•
Check that the chain is fitted correctly. If the bicycle fell onto the transmission side, check that it is working
properly. Ask for help to place the bicycle on its saddle and change gears. When the chain fits on the largest
cog, check the distance between the gear and the spokes. If the gear or bracket are bent, the first one may
become stuck on the spokes - Danger of falling! The gear, rear wheel or frame may be damaged. Check the
derailleur. If it has shifted, the chain may come off the gear. The bicycle's transmission will become less
effective (alsorefer to the "Traction" section).
•
Check the saddle, upper tube or the bottom bracket box to make sure that there are no defects.
•
Lift the bicycle slightly and let it drop onto the ground. If there are any noises, inspect the bicycle for any
loosebolts.
•
Inspect the entire bicycle again to check for bent areas, worn finish or cracks.
•
Ride again carefully if no problems have been detected during the inspection. Do not brake or accelerate
suddenly or pedal when going uphill. If you are unsure, wait for a car to pick you up instead of risking an
accident. Once home, you should inspect the bicycle carefully again. If you are still unsure or have any queries,
please contact your nearest BH workshop!
Bent aluminium parts must not be straightened, i.e., they must not be repaired. Even afterwards, thereisahigh
risk of breakage, especially in regards to the fork, handlebars, front part, chainsets and pedals. Replace them
for greater safety.
