The Thudbuster ST uses a shorter parallel-linkage mechanism to yield the ideal suspension post for riders looking to 'take the edge off' bumps with less loss of weight penalty.
A neoprene cover which fits over the parallelogram and secures with hook and loop fastening system to protect the suspension mechanism in foul weather and prolong performance.
The USE Shims are designed to allow you to use your 27.2mm (outer diameter) seatpost, and securely fit it to frames that use larger diameter seat posts and clamps. Simply select the shim size that matches your frames inner seatpost diameter and then you slot your seatpost into the shim and place the shim and post into your frame, making sure you clamp the shim for a secure fitting.
