Why do my ST elastomers pop out while riding?

Perhaps you have installed your Thudbuster ST seatpost backwards.  Be sure the height markings face the front of the bike! Here is a link to our Thudbuster ST Installation Guide

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.

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

The suspension mechanism requires at least 101mm (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.

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

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

What does minimum insertion line mean?

The minimum insertion line represents the least amount of seatpost length required to be installed inside the bicycle’s seat tube. Thudbuster requires a minimum of 100mm of insertion for all models.

What if my bike uses a different size seat post other 27.2, 30.9 and 31.6mm?

Cane Creek offers various seatpost shims to accommodate a variety of seatpost diameters larger than 27.2. Click on the link provided to see the shim sizes that are available. Seatpost Parts and Accessories

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

The Thudbuster follows standard seatpost diameters. 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 Insertion” line toward the bottom. The number will be a three-digit number (such as […]

How do I change the spring rate on my Thudbuster?

Thudbuster ST uses a two piece elastomer system. The inner elastomer can be pressed out by hand, and exchanged with the desired spring rated elastomer.

Can I tune the Thudbuster for my weight?

Yes. Every new Thudbuster ST seatpost includes a set of elastomers to fit your weight and riding style. The Thudbuster will come with a medium firm elastomer (150-200lbs / 68-90kg rider weight) pre-installed in the post. Thudbuster will also come with a Soft Elastomer (100-150lbs / 45-68kg rider weight) and a Firm elastomer (200-250lbs / […]

What kind of spring does the Thudbuster use?

The Thudbuster uses a rubber-like material (a polyurethane elastomer) combined with two pivoting arms to suspend the rider.
