Danger:
The minimum insertion
depth of your seat
post in the frame is
100 mm. Never ride
your STEVENS bicycle
if the marking (MIN,
MAX, STOPP, END or the
like) of the seat post is
visible.
Carbon Seat Posts
Insert carbon seat posts only in frames with suitable seat post clamping. Spe-
cial seat post clamps reduce the forces occurring at the clamping slot. Clamping
areas with two or more clamping slots are perfect. They provide an even spread-
ing of the clamping forces, reduce the occurring pressure and hence the risk of
breakage.
Mounting the Seat Post
Make sure that your new seat post has the same diameter as the seat tube of
your frame. You should be able to insert the seat post easily into the frame without
pressing or turning. A mismatch between frame and seat post can cause failure
of the seat post.
Before mounting the seat post to the frame, Make sure that the seat tube is
absolutely free of lubricants, sharp edges and burrs. Clean and deburr the seat
tube, if necessary.
Make it a rule to tighten the bolt of the seat tube clamp always very care-
fully. Increase the torque values bit by bit and check the fit of the component in
between. Use a torque wrench and do not exceed the maximum torque values!
You find them on the components themselves and/or in the instructions of the
component manufacturers. Use special carbon assembly paste to increase the
clamping force.
Danger:
Even a slight mismatch between seat post and seat tube diameter or oil
and grease in the seat tube can lead to a rupture of the carbon seat post.
This can result in an accident or injury to the rider. Use special carbon
assembly paste to increase the clamping force.
Mounting the Aero Seat Post with Top Tube Clamp
Some STEVENS models are equipped with an aero seat post.
Before mounting the aero seat post into the frame, make sure that the seat
tube matches the aero seat post and is absolutely free of sharp edges and burrs.
Before mounting the aero seat post apply a little carbon assembly paste to the
bottom part of the seat post, inside the seat tube of the frame and on the contact
surfaces of the clamp mechanism towards the seat post.
Loosen the Allen bolt on the seat post clamp on the top of the top tube by two
to three turns anticlockwise without undoing it completely.
Now, the aero seat post can be vertically adjusted.
The seat post has to slide easily without pressing. If it does not, loosen the
clamp a little more.
For more information on the correct saddle height read the chapter
“Adjusting
the Saddle to the Correct Height””
.
Do not pull the seat post up beyond the existing marking. Clamp the seat post
again. Do this by tightening the Allen bolt at the seat post clamp on the top of the
top tube to the indicated torque value. Use a torque wrench and do not exceed the
maximum torque values!
Caution:
Measure the saddle height of your previous road racing bicycle from the
centre of the bottom bracket to the top edge in the middle of the saddle.
Adjust the saddle height then to your new STEVENS road racing bicycle.
Danger:
Never apply any grease
or oil to clamping areas
made of carbon!
Danger:
Do not ride your
STEVENS road racing
bicycle when the MAX
marking is visible on the
seat post.
