Adjusting Brakes And Recommendations For Replacing Friction Brake Components - Decathlon B'twin Manual Del Usuario Y Garantía

Changing gear: continue to pedal but not too hard and move the gear shifter (lever or rotating handle) until the chain is positioned on the selected chain ring or cog.
Each lever position corresponds to a different cog. If the chain has a tendency to slip off the cog: you can try «overshifting» by gently pushing the lever slightly beyond current position
without moving to the next position.
If this still doesn't work: you will need to adjust the cable tension.
• If the chain does not move down easily, refer to chapter on «adjusting the gear system.» The chain should move smoothly between cogs.
Warning:
To ensure that the gear systems function correctly and to extend service life of drive train parts
(chain, free wheel, pedals):
Avoid sudden, aggressive gear changes. Avoid crossing the chain (using large cog and large chain ring
or small cog and small chain ring).
If the chain is crossed (diagram 2) it may be in contact with the front derailleur.
Warning :
To ensure optimal use of the manual or automatic gear change system, you are advised to avoid
changing gears during periods of intense pedaling and to shift to a lower gear before stopping so it's
easier to start off again.

15. ADJUSTING BRAKES AND RECOMMENDATIONS FOR REPLACING FRICTION BRAKE COMPONENTS

The brake lever must not come into contact with the handlebar. Avoid creating short, sharp bends in the outer casing to ensure the cables can run smoothly.
Damaged, frayed or rusty cables must be replaced immediately.
The brake pads must be aligned with the edge of the rim (at a distance of 1-3 mm). They must never touch the wheels. Disc brakes must be checked regularly; check all the brake
screws and check brake pads for signs of wear; the minimum thickness should be 1 mm. Brakes must be adjusted as outlined in section «Preparing for use.» You are advised to get a
qualified mechanic to carry out these adjustments.
When replacing brake parts, to ensure the continued performance of your bike, you are advised to use genuine spare parts. This procedure must be carried out by a qualified mechanic.
DISMANTLING WHEELS FITTED WITH BAND BRAKES (ROLLER BRAKES)
Dismantling and re-assembling this type of wheel can be tricky; we recommend asking one of our technicians. Nevertheless, you may carry out the following operation by yourself:
Dismantling :
.disconnect the cable by loosening nut
[5]
. loosen the wheel clamping nuts
[3] by releasing the wheel from the frame and loosening nut [4]
. separate the cam and dropout
-Re-assembly and adjustment of cable tension :
.fit the wheel at the bottom of the dropouts without tightening
[3]
.fit the brake dropout
.fit the wheel properly, referring to the chapter on chain tension and checking for truing
[5]
.tighten up the wheel nuts to the recommended torque
[4]
.tighten up brake dropout nut if necessary(closed cam)
[6]
.tighten cable adjuster right up
[1]
.replace the cable, move nut back up and stretch the cable so it no longer gives at all, tighten nut
[1]temporarily and check that the wheel moves freely when the brake
has not been applied. .if it has been properly adjusted, tighten nut [1]
up, adjust the cable tension if necessary using the adjuster
bicycle out in order to detect any other malfunctions.
