The Drivetrain: Pedals, Chainring, Chain And Cassette - Orbea ALMA Manuel D'instructions Et D'entretien

this movement is natural, practice in a flat area without traffic. While pedaling, watch the road.
If you are looking at the pedals, you may not see the obstacles ahead.
Do not use clipless pedals with street shoes, since your feet will not have a good support base
on the pedal.
Remove at least one foot from the pedal before stopping the bicycle completely.
Inspection
Before every use, you should clean both the cleats and the pedals, since any dirt could interfere
with the proper functioning of the mechanism.
Every three months, check that the pedal reflectors are clean and correctly positioned. Make
sure the pedals are properly secured to the crank arms.
To check that the pedal bearings are well-adjusted, move the pedals up and down and left to
right. If you feel that anything is loose or too stiff, take the bicycle to your dealer so they can be
adjusted, lubricated or replaced. The pedal-to-crank arm torque should be 40-43Nm.
Adjustment
Improper installation of the cleats could cause physical injury; therefore, cleats should be posi-
tioned by the authorized dealer. In most clipless pedals, the force needed to insert and remove
your foot can be regulated.
Getting into clipless pedals
Fit the front of the cleat into the front of the pedal and push downwards with your foot. It will
"click" when it is in position.
Check that the connection is secure by rotating the pedal. If your shoe comes out, repeat the
previous step.
To mount your bike, push the pedal downwards while pushing forwards with the other foot,
while sitting on the saddle.
Once in motion, insert your other foot into the pedal using the same technique.
Getting out of clipless pedals
Twist your heel laterally with respect to the central line of the bike.
To stop, put your foot on the ground.

4. THE DRIVETRAIN: PEDALS, CHAINRING, CHAIN AND CASSETTE

The bicycle's drivetrain transmits power to the back wheel through:
- Pedals
- Chainring and crank arms
- Chain
- Cassette
This section will explain how to inspect, adjust and lubricate the drivetrain. For bikes with rear
internal hub gears, see the section on "Internal hub gear system".
Inspection
When the drivetrain is functioning properly, shifting is easy and silent.
Once a month, check that the cassette and chain are clean and well oiled. All links in the chains
should pivot well without squeaking. Likewise, check that no links are deformed. Remove the
rear wheel and spin the cassette. If you hear a strange noise or if the cassette stops as soon as
you let go, it may need to be repaired or replaced; take the bike to your authorized dealer.
Once a month, if your bike has a chainguard, check that it is securely attached and aligned. Try
to move the chainguard from one side to the other and tap it. Lift the rear wheel and turn the
crank arms to hear if the chain or the chainring is rubbing against the chainguard. Realign the
chainguard and adjust the screws so it is secure.
Inspect your pedals every three months. Check that the pedal reflectors are clean and correctly
positioned. Make sure the pedals are properly secured to the crank arms.
To check that the pedal bearings are well-adjusted, move the pedals up and down and left to
right. If you feel that anything is loose or too stiff, take the bicycle to your dealer so they can be
adjusted, lubricated or replaced.
Every three months, inspect the crankset and check that the bolts are secured. The following
torques should be applied:
Single chainring binder bolt: 40-50Nm
Crank arm binder bolt: 15Nm
Chainring bolts: 8-10Nm
Chainring adjustment check
- Shift the chain to the largest chainring.
- Spin the chainrings until the crank arms are parallel to the seatpost.
