Adjusting the tilt of the handlebars
and brake levers of CENTURION road
racing machines and CENTURION
cyclo-cross bikes
The ergonomically best position is achieved with the
straight extensions below the drops in parallel to the
ground or pointing slightly downwards towards the
rear (d) . The ends of the brake lever/shifter units
should meet an imaginary extension of the bottom
line of the drops, the upper part of the lever will then
be in horizontal position or point slightly upwards.
Shifting the brake levers/shifters is a job best left to
your CENTURION dealer, as it involves retaping the
handlebars afterwards.
To adjust the tilt of the handlebars, release the Allen
bolt(s) on the underside or front side of the stem (e) .
Turn the handlebars to the desired position. Make
sure the handlebars are accurately centered in the
stem (f) .
Tighten all bolts with an Allen key by applying little
force until the upper and the lower clamping slots of
the handlebar clamp between faceplate and stem
body are equal in width. Tighten the bolts alternately
and in small increments with a torque wrench to the
lower value of the recommended torque values. The
recommended torque values for 4-bolt-stems are
5-6 Nm. In the case of 4-bolt-faceplates tighten the
bolts evenly in a cross pattern.
Exception: some Procraft stems. Read in this re-
gard the chapter “Special case Procraft ST1 und
ST1.17” and the manufacturer’s instructions on this
CENTURION CD-ROM.
Once clamped in the stem try rotating the handlebars
and tighten the bolt a little more, if necessary. Use
a torque wrench and never exceed the maximum
torque values given in the chapter “Recommended
torque settings”, directly on the components and/or
in the instructions of the component manufacturers
on this CENTURION CD-ROM.
Special case Procraft stem ST1 und ST1.17
During the assembly of the stem models Procraft
ST1 und ST1.17 make sure the white spots point
upwards.
Tighten the two stem bolts marked with a spot on the
side to a torque of 5 Nm by using a torque wrench.
During tightening the gap closes to the full. In the final
position the gap has disappeared (g) .
Continue by tightening the two bolts on the other
side also to a torque of 5 Nm.
A gap remains open (h) .
g
Observe the prescribed torque values
and do not exceed them!
i
Observe the details in the instructions
of the brake and gear manufacturers.
If you have any questions contact your
CENTURION dealer.
