If the lever does not close tightly enough:
WARNING Danger from falls and accidents
If the lever is too loose when closed, the saddle post may suddenly slip down a long way while the bike is
being ridden. This can lead to dangerous riding situations, falls and accidents.
– Open the lever.
– Turn the knurled nut slightly in a clockwise direction (as seen from the left).
– Close the lever again.
If the lever closes too tightly:
WARNING Danger from falls and accidents
If the lever cannot move in its final position (90° to the hub axle) because the pre-tension is too great (see
illustration), the lever may become loose while the bike is being ridden and the saddle post may suddenly
slip down a long way. This can lead to dangerous riding situations, falls and accidents.
– Open the lever.
– Turn the knurled nut back slightly in an anticlockwise direction (as seen from the left).
– Close the quick-release lever again.
8.6.4 Screw-nut clamping on wheels
WARNING Danger from falls and accidents
Incorrect installation of the wheels using the quick-release hub axle can lead to dangerous riding situa-
tions, falls, accidents and material damage.
• You should have wheels with a screw-nut clamping only opened and closed by a specialist workshop.
8.6.5 Opening and closing the screw-nut clamping on saddle posts
You need an Allen key and a torque spanner with a hexagonal socket of size 4 and 5 mm.
8.6.5.1 Opening the screw-nut clamping on the saddle post
1. Loosen the clamping bolt(s) by a few turns until the saddle post can be easily moved.
8.6.5.2 Closing the screw-nut clamping on the saddle post
NOTE:
Connect the saddle post clamping only if the saddle post is located in the saddle tube.
Closing without an inserted saddle post may cause irreparable damage to the frame.
1. Check the tightness of the clamp. The clamp must sit flush on the saddle tube.
2. Retighten the clamping bolt/s with the torque spanner. Prescribed tightening torque: 5-8 Nm for alu-
minium frames or 5-6 Nm for carbon frames
WARNING Risk of falls and accidents
If the tightening torque is too high, this may damage your saddle post. This may then break while
you are riding the bike and result in a serious accident.
• It is essential to use a torque wrench when tightening the clamp bolt(s) and comply with the speci-
fied tightening torque.
• For saddle post clamps with a knurled nut and quick-release lever you should ask your dealer to
show you how tight these may be tightened.
9. Loading the Bike
WARNING Danger from falls and accidents
Adding an extra load impairs the riding behaviour of your bike and the braking distance becomes longer.
And if you overload your bike, it is possible that parts of it might even break or fail. All of this can lead to
dangerous riding situations, falls and accidents.
• You should load your bike in such a way that you always have enough room to move and can always oper-
ate your bike safely when it is loaded.
