Installation Instructions
-
Note your current saddle height and fore/aft position to duplicate it with the Thudbuster. 2. Remove your current saddle and Seatpost. Confirm your current saddle is compatible with Thudbuster. Thudbuster is only compatible with saddles using round alloy rails.
-
Confirm your new Thudbuster Seatpost (or shim) diameter is the same as your old Seatpost. (Thudbusters are available in three direct fit sizes, 27.2, 30.9, and 31.6mm.)
-
Grease the shim (if applicable) and seat pillar before installing. DO NOT lubricate seat tubes of Carbon frames (unless specified by the manufacturer).
-
Insert the shim (if applicable) into the bicycle frame with the split aligned with the split in the seat-tube.
-
Install the Thudbuster into the bicycle frame to approximately the correct height with the extension marks on seat pillar facing the front of the bicycle.
-
Loosen the saddle clamp bolt until the saddle rails can be installed into the seatpost clamps.
-
Begin to tighten the saddle clamp bolt. Ensure your saddle tilt angle is correct before tightening completely.
Tighten the saddle clamp to 16Nm MAX. Be sure all the components of the clamp are installed as shown above. -
Adjust the saddle height if necessary.
NOTICE! The Thud buster must be set-up with appropriate elastomer before riding (See below). Maximum allowable rider weight is 330 lb (150kg).
Selecting Elastomers
The Thudbuster ST can be tuned for different weight riders and riding styles
by selecting the correct elastomer. Start with the softest elastomer
recommended for a given rider weight. The
Thudbuster ST is shipped with medium elastomer installed. You may desire to
decrease or increase the stiffness by using a softer or harder elastomer.
Optional Thudbuster elastomers can be purchased at your local bicycle dealer.
Never us a softer elastomer than recommended for your weight.
Changing Elastomer
Cane Creek’s Short Travel Thudbuster Elastomers consist of an Outer and an Inner Elastomer. The Inner Elastomer can be removed by hand without any disassembly of the Seatpost and be changed to the firmness rating needed for rider weight (Reference the elastomer weight range guide to the right). Remove the inner elastomer by pushing horizontally.

NOTICE! If you ride in muddy conditions, using either a fender or the Cane
Creek Thud glove neoprene boot will protect the pivots and extend the life of
your Seatpost.

riding surfaces.
However, you should still stand up when encountering large obstacles on the
road or trail.
