Cane Creek Thudbuster ST (G4) Suspension Seat Post 30.9mm x 375mm

A great short-travel suspension seat-post that takes the edge off those bumpy roads and paths. Ride longer with less fatigue. Comes with three different elastomers for softer or firmer feel. This one is 30.9mm diameter and works great on many Specialized electric-assist bikes, or conventional bikes with 30.9mm seat-tubes. Recommended by us!
