Setting up the seat height

increasing amount of resistance after closing the lever about half way. If
the component is not properly or insufficiently fastened, turn the opened
quick release lever clockwise by half a revolution. Then close the lever
and test if the wheel is now tightly attached. If the component is not tight
or securely tightened enough, then open the quick release lever and
rotate it clockwise by 180 degrees. Then close the quick release lever
and test the component again for tightness.
For example: Grip the front and rear wheels on the tyres and shake them
strongly in a lateral motion. The wheels should remain tightly in place.
When closed, quick release levers should be flat against the frame,
fork or seat post and should always point backwards! This ensures
that they cannot be opened through contact during riding.
More information about quick releases is provided in the “Technology” chapter.
Check that all quick releases are properly fastened before every ride!
Setting up the seat height
There is a simple process to test the height of your seat: Sit on the seat and the heel of your fully
stretch leg should sit on the pedal at the bottom of its cycle. In contrast, with the balls of your feet on
the pedals, your leg should be slightly bent when the pedals are at their lowest point.
When adjusting the height of the seat, you must leave a minimum insertion length of 7.5 cm (10 cm
for longer seat tubes that stick out above the level of the top tube). This minimum insertion length
is usually clearly indicated, and it is very important for your safety! The seat clamping bolt is either
opened anti-clockwise and closed clockwise with an allen key; or it is attached to a quick release
mechanism. The same applies when adjusting the tilt of the seat.
Please ensure you use the correct torque for the bolts!
Suspension seat posts, which are designed to take some pressure off the spine, should be
set up by your specialist retailer.
The handlebar assembly consists of the stem, the handlebar itself, controls and the headset.
The position of these components has a great influence on your ultimate seating position and the
resultant posture. Ultimately, the seating position is governed by the height difference between the
handlebars and the seat. Low handlebars increase the pressure on the upper body, arms and wrists,
while higher handlebars put more load on the spine. The best way to find the best setup for you is
with the help of a partner who holds the bicycle in place while you bend your upper body forward
bit by bit while sitting on the bicycle and stretching your hands towards the handlebars. Specialist
retailers can also be a good source of advice here too.
Setting up the handlebar position
When setting up or adjusting the position of your handlebars, it is vital to ob-
serve the 6.5 cm minimum insertion length of the handlebar stem or observe
the STOP marking on the stem – otherwise the stem could be unstable.
With conventional handlebar stems, you first have to loosen the stem spindle
with an allen key anticlockwise, while holding the front wheel between your
knees. Twist the stem shaft back and forth or knock on the spindle with a
plastic mallet from above until the clamping screw is released. Then adjust
the stem to the desired height and orient the handlebars so that the stem
forms a right angle with the frame. Then tighten the spindle clockwise with the allen key (take note
of the correct torque!).
The height of A-head systems should always be adjusted by specialist
retailers.
The same applies for setting up adjustable stems. They have to be adjusted
by specialists.
Adjusting this part of the bicycle incorrectly could lead to very serious falls
and injury!
The alignment of the handlebars in their horizontal position can be changed
by loosening the lock bolts on the front side of the stem in a clockwise direc-
tion, adjusting the position of the bar as desired and then tightening the screw
back to the prescribed torque. Please ensure that the handlebars are exactly
in the middle of the stem.
If your bicycle is equipped with an adjustable stem, you can adjust the height
and distance to your handlebars as you wish. This is done by changing the
tilt of the stem.
To do this, loosen the allen bolt located on the side of the stem by turning it
several times with an allen key. You should now notice that you are able to
move the stem. Please ensure that you do not turn the screw so much that
the individual parts of the stem fall apart. When the internal locking system
is loose enough, you should be able to move the stem upwards and down-
wards. Move the handlebars into the desired position and tighten the allen
screw again. The required torque is stated on the side of the stem.
Please note that this process also twists the handlebars. Now you have to
adjust the handlebars into a position in the stem in which you can easily and
safely operate that brakes and gears! A brief instruction on how to do this is
outlined in the section “Adjusting the bicycle to the rider”.
