Designed with the rigors of daily commuting and electric bikes in mind, the Cane Creek Thudbuster ST (short travel) seat post offers 50 mm of travel to smooth out your ride.


  • Post is crafted from forged aluminum; pivots feature threaded, serviceable, hard-anodized aluminum axles and flanged PTFE bushings
  • 50 mm of vertical travel works to significantly diminish shocks and impacts from broken pavement, cobblestones or any other mixed surfaces
  • Thudbuster Parallel Linkage technology compresses along the opposite path of a bump (down and rearward) to absorb the force
  • This design results in a natural suspension feel without being overly active, and it offers more travel without compromising your pedaling position
  • Seat clamp features single-bolt fastening and an angle-adjustable design
  • Includes a Medium Firm elastomer pre-installed from the factory; tool-free elastomer changes offer ease of use (Extra Soft, Soft, Firm and Extra Firm elastomers not included)
  • 345 mm seatpost features a 274 mm max extension and 100 mm min extension
  • 330 lb. rider weight limit

Made in USA.
