The Thudbuster seatpost from Cane Creek is the most effective and versatile suspension seatpost available.  Our parallel-link technology provides a clear advantage in traction, comfort and control without sacrificing performance.  Available in both Long Travel and Short Travel configurations, with a range of elastomer spring rates, the Thudbuster is tunable to match your weight and riding preference.


Working in the direct path of the natural travel of the rear wheel.

The Thudbuster technology stays in the direct path of the natural travel of the rear wheel. As a bump lifts the back of a bicycle, the rear wheel pushes up and foward into the rider. The Thudbuster works by compressing along the exact opposite path -- down and rearward -- absorbing force at the same rate: The net movement of the saddle is zero. Fully active elastomers provide approximately 3 inches (76mm, Long Travel) or 1.3 inches (33mm, Short Travel) of customizable suspension.

Thudbuster Applications

Riders of all types of bikes around the world rely on Thudbuster to provide higher levels of performance and comfort.

Hardtail Mountain Bikes
The hardtail resurgence is real. Endurance, single-speed and 29er riders are quickly discovering that simple damping technology yields vast improvements in ride quality and control.

Long, rough road rides become less fatiguing and more comfortable. The Thudbuster is perfect for touring and "cause" riders who find traditional saddle/post combos uncomfortable.

A happy stoker is essential to fun on a tandem. A Thudbuster can make the difference between a beaten-up rear end and just a little bump now and then.

Folding Bikes
Small-wheel bikes with high-pressure tires directly benefit from Thudbuster suspension.

In order to accomodate an engine, e-bikes feature, in general, very stiff and unforgiving frame designs. They are also ridden primarily in the saddle, rather than standing. The Thudbuster takes the edge off without changing the angle of your body in relation to the pedals.


Parallel-Linkage Technology

Design has none of the stiction of telescoping posts, delivering continuously responsive travel to increase performance and comfort.

Versatile Tuning

The Thudbuster comes in two versions: LT (Long-Travel), for maximum suspension control, and ST (Short Travel), for cushioning impacts while saving weight.

Reliable Durability

Forged linkage rides on widely spaced bushings to increase lateral stiffness and deliver stable performance.

Easy Serviceability

Split linkage arms enable ease of disassembly and simple bushing replacement.


Electric Bike Report: "The Thudbuster Long Travel gives you some three inches of downwards and backwards travel and its plenty to soak most of the punishment dished out on the UK’s often very poor roads. I even ventured onto better quality dirt tracks and paths without any problems." Full Review Here 

Velonews:  "We included this mountain bike suspension post to see how it stacked up against more traditional designs...As noted and expected the flex of the Cane Creek Thudbuster /ST greatly exceeded that of all the other seatposts".  Full Review

Harry - Centereach, NY says "Just want to THANK you for the Thudbuster LT, it's got my bad back issues out of the way and riding again! I had issues that almost forced surgery, and had to give up biking years ago when a Dr suggested it would be too much for me anymore. The Thudbuster gave me my freedom back,and I love you guys for it, Truly..  :)"  With the potential for 1.5″ of ‘travel’ and adjustable elastomers, it is a good solution to tired backs on long days in the saddle over bumpy roads.  A classic piece of kit.
