Seat Tube/Binder Preparation
Burrs or sharp edges of the seat tube insert opening can scratch the seat post. Before inserting
the seat post into the frame, do the following:
1. Remove the seat binder exposing the seat tube insert.
2. Lightly round the opening of the insert using 240 grit or lighter sand paper.
3. Apply carbon gel into the opening of the seat tube. Carbon gel has been included in the parts
boxes of 2009 Synapse Carbon. It is also available by ordering Cannondale kit KF115/.
4. To improve clamping force, lightly grease the outside surface of the seat tube insert before
reinstalling the seat binder.
5. Reinstall the seat binder.
6. Before inserting the seat post, apply carbon gel to the seat post.
7. Use a torque wrench to tighten the seat binder bolts to 6 Nm.
