Torque Specifications 2.8 Nm
The Thomson Seatpost Collar can generate high force. The bicycle frame and
seatpost might get damaged if the seatpost collar is overtightened.
Make sure that your frame seat tube is free of any burrs or peeled paint. You may
want to gently sand the frame to achieve a smooth finish.
Do not grease under bolt head or washer. Lightly grease the top of the seat tube.
Grease only the threads of the barrel nut.

Increase torque incrementally until the saddle no longer twists. Do not attempt to
fix a slipping or creaking seatpost by overtightening the seatpost collar. Diagnose
what is causing the seatpost to slip.
If your seatpost still slips after you have tightened to maximum torque,
follow these steps:
1. Remove excess grease on post and frame.
2. If post rocks or "chucks" in seat tube when there is
no collar pressure, seat tube is slightly large.
Use seatpost shim to eliminate slop.
