Seat binder Sizing
Large and Medium size frames each require a specifically sized seat binder. The BINDER SIDE CODE is stamped into frame
binder node in the position indicated. Cannondale seat binder replacement part numbers appear in the graphic above.
Seat binder Maintenance
Periodically, to keep the seat binder in good working order, remove the seat post and remove the seat binder from the frame.
This will enable you to clean the seat binder, the binder bolt, and barrel nut as well as the frame mating surface.
Apply a light film of bicycle bearing grease to the bolt threads and mating surfaces of the binder node before re-installing
the seat binder onto the frame.
Seat post Installation
Consult the seat post manufacturer’s installation and maintenance instructions for your specific seat post.
Always use a torque wrench when tightening the binder bolt.
We recommend using carbon gel inside the seat tube for both alloy and carbon fiber (composite) seat posts. Carbon gel is
available as Cannondale kit
KF115/
.

Cannondale Bicycle Owner’s Manual

chain tension adjustment should be performed only by a professional bike mechanic .
Prior to checking tension, the chain should be inspected and lubricated which can be accomplished by removing the chain ring
cover. Chain tension is adjusted by rotating the eccentric assembly with the bottom bracket shell. In the illustration above, the
left-crank arm is shown removed above for clarity. It is not necessary to remove the crank arms to adjust chain tension.
To adjust the chain tension
1. Insert a 4 mm Allen key into the eccentric wedge fixing bolt and turn it counter-clockwise a few turns to loosen it. The
inside of the bottom bracket shell is lubricated with grease and the wedges should release easily. However, it is possible they
may stick. If this happen, with the Allen key inserted into the fixing bolt, lightly tap the Allen key with a hammer to free the
wedges.
2. When the eccentric is free to rotate, insert a pin spanner (Park SPA-2 shown) into eccentric holes and use the tool to slowly
rotate the eccentric in the shell. Rotate counter-clockwise to increase chain tension. Rotate clockwise to decrease chain
tension. Rotate the crank arms to confirm the correct tension.
3. When your are finished, use a torque wrench to tighten the fixing bolt to
13.0 Nm, 115 In lbs
.
NOTIcE
Too much chain tension can prematurely wear the chain and cause hard rotation. Too little chain tension can result in
the chain dropping from the chain ring or causing noise within the chaincase.
