What is the setback on the Thudbuster?

Thudbuster LT: 13.5mm Thudbuster ST: 10.9mm   These are the setbacks of the static (unweighted) seatposts.  The setback will change once seated on the seatpost, and that amount will vary based on rider weight, elastomer choice, and bicycle geometry.

Can I use my existing saddle with the Thudbuster?

Yes. The Thudbuster uses a typical saddle-clamp mechanism, allowing you to use any saddle that has the standard double-mounting rail design.

Is there a way to fit the Thudbuster suspension onto my existing seatpost?

No. The Thudbuster is a complete seatpost that replaces your existing seatpost.

My saddle in really low. Will there be enough room for the Thudbuster’s suspension mechanism on my bike?

The suspension mechanism requires at least 144mm (LT)/98mm (ST) from the saddle rails to the bicycle frame. This is a reasonable clearance that almost all riders with a properly sized frame will have.

How do I know what diameter (size) to order?

Different bicycles require different diameter seatposts. To find out the diameter of your seatpost, you must remove the seatpost from the bicycle frame and look for the size, which is stamped just below the “Minimum Insert” line toward the bottom. The number will be a three-digit number (such as 26.8 or 27.2 or 31.6). If […]

What kind of spring does the Thudbuster use?

The Thudbuster is an elastomer-based suspension system. The elastomers are constructed of a special blend of polyurethane in five different durometers (stiffnesses). Each elastomer is centrifuge-cast at 300 times the force of gravity to ensure the best quality and highest durability possible.

Can I tune the Thudbuster for my weight?

Yes. Every new Thudbuster ST & LT seatpost includes a set of elastomers – Soft (#3), Medium (#5), and Firm (#7) – to fit your weight and riding style. For really light and heavy riders, we also make Extra Soft elastomers (#1) and Extra Firm elastomers (#9). All elastomer options are available on our Seatpost […]
