Elastomer-Based
LIGHTWEIGHT, QUIET, CONTROLED - Thudbuster's suspension movement is powered by elastomer springs. We chose these super dense blocks of polymer because they offer several key benefits over metal coil springs. Elastomer springs are lighter, quieter, and don't bounce erratically. They’re not as likely to creak and squeak as coil-sprung seatposts and their motion is very well controlled. Elastomers are inherently self-damping, meaning that the rebound properties of the material can be engineered so that the seatpost has a very smooth and controlled motion, especially when re-extending after being compressed. Thudbuster moves naturally, disguising its presence until it’s needed. No bouncing, and no pedal ‘bob.’
Which One is Right for Me?
Thudbuster ST
Better for riders with minimal seatpost extending from the frame.
Higher rider weight limit : 330lbs / 150kg
Less suspension movement than LT - ideal if attaching bags or accessories to seatpost (touring, bikepacking, commuting, ect)
Thudbuster LT
Maximum comfort & bump absorption
Noticeably more suspension than ST
Requires about 6 inches (or 146mm) of minimum seatpost extension from frame
Rider weight limit : 250lbs / 113kg
Which elastomers are included?
Thudbuster ST comes with 3 mid-range elastomer choices. Thudbuster LT comes with medium elastomer installed. Additional elastomers for both seatposts sold separately.
Customizable Ride Feel
Choose between 5 different elastomer springs to fine tune the ride feel of Thudbuster. Whether you want it super soft and forgiving, or more firm and supportive, we offer a range of elastomer springs to suit riders of all sizes and preferences.
