or take the bicycle to your bicycle dealer for repair, if you are in any doubt.
14 Adjusting the Bicycle to the Rider
Your body measurements are decisive for the frame size of your bicycle.
Make particularly sure there is enough space between your crotch and the
top tube so that you do not hurt yourself, if you have to get off your bicycle
quickly .
If you have a very small frame, there may be a danger of your
foot colliding with the front wheel. Therefore, make sure your
cleats are properly adjusted.
By choosing a specific type of bicycle you roughly determine the posture
you will be riding in . However, some components are designed in a way
that you can adjust them to your proportions to a certain degree, such as
seat post, stem and brake levers. Contact your bicycle dealer. He will see to
your wishes the next time you leave your bicycle at the workshop, e.g. for
the first inspection.
After any adjustment/assembly work, be sure to make a short functional
check as described in chapter and do a test ride in an
area away from traffic. This will allow you to safely check whether everything
is in good order.
All tasks described in the following require the know-how of a mechanic and
appropriate tools. Increase the tightening torque bit by bit, checking the fit
of the component in between. Use a torque wrench and never exceed the
maximum tightening torque! You will find the prescribed values in chapter
, directly on the components and/
or in the manuals of the component manufacturers.
The correct saddle height for almost all bicycle types is the height which gives
maximum pedalling comfort and efficiency. When pedalling, the ball of your
foot should be positioned above the centre of the pedal spindles . With your
feet in this position you should not be able to stretch your legs completely
straight at the lowest point, otherwise your pedalling will become awkward.
Check the height of your saddle with flat-soled shoes. This is best done with
suitable cycling shoes. Sit on the saddle and put your heel on the pedal at
its lowest point . Your leg should be fully stretched and your hips should
remain horizontal.
To adjust the saddle height loosen the quick-release lever (see chapter
) or the binder bolt of the
seat post clamp at the top of the seat tube. The latter requires appropriate
tools, e.g. an Allen key, with which you turn the bolt two to three turns anti-
clockwise. Now you can adjust the seat post.
