MAINTAINING BAND BRAKES (ROLLER BRAKES)
.Check cable tension (see chapter «Re-assembling the wheel»).
The extent of wear on the hub brakes required the drum itself to be removed This operation must be carried out by a workshop technician.
.The hub brake must be replaced by an identical one to ensure that each type of bicycle brakes properly as designed.

16. GENERAL MAINTENANCE RECOMMENDATIONS

Your bike needs a minimum amount of maintenance and regular check-ups, depending on how much you use it: regularly oil the chain, brush cogs and chain rings, occasionally apply
a couple of drops of oil to the outer casing of the brake cables and the derailleur, and remove any dust from brake pads. Regularly check the tyres for excess wear, cuts, slashes or
toe wear and replace the tyre if necessary. Check the rims for signs of excessive wear, dings, dents and cracks. Your bike should be serviced regularly by a qualified mechanic. The
frame, the forks and all the components must be regularly checked by our b'Twin After-Sales Service team to detect the signs of wear and/or potential deterioration (cracks, corrosion,
damage...). These are important safety checks which help avoid accidents and physical injury and ensure the lasting health of your bicycle.

17. IMPORTANCE OF USING GENUINE SPARE PARTS

When you replace components, you must use genuine spare parts to ensure good performance and reliability. This proce-
dure must be carried out by a qualified mechanic.
Warning!
When replacing the pedals, wheels, mud guard or crank, the minimum distance between the edge of the wheel or mud guard
and the pedal axle must exceed the measurements given below.
Minimum distance D
D>89 mm for road and children's bicycles D>100 mm for mountain, City and trekking bikes

18. MAINTENANCE OF WHEEL RIMS

As with all wear pieces, the rim must be checked regularly. If you notice anything strange (unusual wear or any warping) have your bike checked by a qualified and experienced mecha-
nic. If your wheel rims show signs of wear, check and if necessary replace them. Reduced wall thickness may lead to tyre defects and cause injury.
19. APPROPRIATE SPARE PARTS (TYRES, AIR CHAMBERS, FRICTION BRAKE COMPONENTS, GEAR COMPO-
NENTS)
When replacing components, it's important to use genuine spare parts. This procedure must be carried out by a qualified mechanic.

For carbon wheels, inflate the tyre to the maximum pressure indicated on the rim independently of the maximum pressure indicated on the
tyre. Warning, carbon rims may have invisible wear and tear. If you are unsure, please contact a qualified technician. Carbon rims may have a
maximum pressure that is different and lower that of the tyres. The tyres should be inflated to the lowest maximum pressure written on the rim
or the tyre.
