Pedals
Pedals come in a great variety of shapes, sizes, and qualities. In the
basic case, the right-hand side pedal (marked with an “R”) has a
right-hand thread, and the left-hand side pedal (marked with an “L”)
has a left-hand thread.
For both pedals this means that they can be tightened towards the
front wheel and loosened towards the rear– you will need a size 15,
preferably long spanner.
If you are using clipless pedals (Figure 15/1), please practice
getting on/off the pedals with the bicycle at rest. The release
strength of most clipless pedals can be adjusted.
Please read the attached information booklet of the manufacturer
carefully!
Drivetrain system
The bicycle's drivetrain system consists of the following components:
bottom bracket, crank with pedals, chain, and cassette (cogset).
The bottom bracket is a part exposed to great stress, which fulfils its
function almost unnoticed. Nowadays, the use of maintenance-free
industrial bottom brackets on bicycles is on the increase. Manufacturers
distinguish between two types of bottom bracket spindles: the traditional
rectangular spindle, and bottom brackets connecting with several splines,
which ensure a more durable and better transmission of force.
The most common bottom brackets follow the traditional BSA system
(left-and right-threaded), or have an Italian thread, with a shell width of 68
or 73 mm. The width of the shell depends on the frame. In most cases,
BSA threads are used, with a shell width of 68 mm. Besides these,
spindle designs of different lengths also exist, depending on the crank
used and the shape of the frame.
Please check the secure attachment of the bottom bracket regularly
(Figure 16).
The crankset consists of right- and left parts. The chainrings are found on
the right-hand side (1, 2 or 3 chainrings, depending on the design).
Please check the tightness of the crank regularly. No play should be felt.
An incorrectly fitted crank could damage the rectangular spindle,
and lead to its breakage. If the crank is not tight enough,
immediately tighten its mounting bolt. If you do not have the appropriate
tool (Figure 17), please turn to your specialist service centre.
The chain, cassette, and chainrings are wearing parts. Their service life
depends on the extent of their use.
