The Thudbuster ST presents all the benefits of the original Thudbuster LT design in a smaller package. The Thudbuster ST uses a shorter parallel-linkage mechanism to yield the ideal suspension post for:
XC riders looking to "take the edge off" with less of a weight penalty
Road riding enthusiasts
Smaller riders and tandem stokers (due to the smaller minimum extension)
Comfort bike owners
The shorter linkage design still provides 1.3 inches of active stiction-free travel. The compression and rebound damping is handled by a single urethane elastomer, which can be changed to fit your size and riding style.
Includes #3, 5, & 7 elastomers - #3 for 100-140lbs, #5 for 140-190lbs, #7 for 190-250lb riders
