Thudbuster ST G4 Suspension Seatpost with Parallel Linkage

Damaged roads, potholes, roots or cobblestones – bike riding can get pretty rough some times. That’s where the Thudbuster ST suspension seatpost from Cane Creek helps.

In its 4th generation, the parallel linkage mechanism continues to be at the core of this proven seatpost with 50 mm travel. Athletic city and trekking cyclists, as well as touring mountain or gravel bikers, will benefit from the suspension on uneven stretches. The level of shock and comfort can be adjusted to the individual rider’s weight with the elastomers of varying hardness levels. Unlike its predecessor, this model has a two-part construction that allows for a tool-free and fast replacement. The saddle mount was also redesigned so that the clamp is secured onto the side, making it easier to install the saddle.

The suspension of the ST model (short travel) is shorter than that of its bigger sister Thudbuster LT (long travel, product code 2303578). Depending on your needs, you can either choose the ST model for athletic comfort or the Thudbuster LT with more travel and longer progression lines, for a softer cushioning.
