WARNING
All seat posts have a minimum insertion line. The seat post must be inserted far enough into the bike
seat tube to cover this line.
Do not ride without properly adjusting the seat post height and securely tightening the seat post clamp
or quick-release clamping mechanism.
Failure to observe the minimum insertion line or properly tightening the clamping mechanism
could result in seat post system failure, which could lead to an accident, with risk of serious injury,
paralysis or death.
Quick Release Seat Post
This type allows a properly adjusted quick release to adjust and clamp the seat without tools. Proper
initial adjustment of the quick release type may be either with a hand adjustable nut, or a nut that is
adjusted with an allen wrench.
1. Hold the lever end of the quick release open and stationary.
2. Turn the adjusting nut clockwise to tighten it. Keep turning until you see or feel it contact the frame.
3. Try closing the lever. Your goal is to tighten the adjusting nut enough so that the lever can be closed
but requires significant force to close. You want it to be hard to close, you want to see the lever
temporarily leave a mark on your hand. If it is not hard to close, open and hold the lever and further
tighten the adjusting nut, try again to close. If it is not possible to close or very, very hard to close,
open and hold the lever and slightly loosen the adjusting nut, try again. Towards the end of the
adjustment process, quite small changes, fractions of a turn, of the adjusting nut are necessary.
4. The lever must be hard to close, the lever must leave a mark on your hand, and the final position of
the lever more than 90 degrees (relative to the bolt) closed.
For all styles, initially tighten the clamp bolt or quick-release clamping mechanism. A good starting point
is to have the saddle about level with your hip. After test riding you will adjust again to tune fit to your
body size and leg length.
Using a torque wrench and the correct size bit, tighten clamp bolts and hidden clamp bolts to the torque
value marked. If no torque marking is present, tighten to 7Nm.
