Cane Creek Thudbuster G4 LT Suspension Seatpost (Black) (31.6mm) (420mm) (90mm)

Cane Creek Thudbuster G4 LT Suspension Seatpost Description:

The Cane Creek Thudbuster G4 LT Suspension Seatpost has been expertly crafted to provide a smooth and stable ride. Using a unique 4-pivot design and a dense elastomer spring, up to 90mm of bump-gobbling travel is provided so the rider will float over broken pavement and rough trails. Additional benefits of this suspension design is that the saddle height is more consistent through the stroke which is much gentler on the riders legs, and pedal-induced bobbing is virtually eliminated. The firmness of the ride is easily adjusted through the interchangeable elastomers, and several diameters are available so a rider can easily find a version of the Cane Creek Thudbuster G4 LT Suspension Seatpost and adjust the performance to suit their bike and riding style.

Features:

• 90mm of travel make this post ideal for XC, gravel, comfort/urban, and e-bikes
• Patented 4-pivot parallel linkage with serviceable hard anodized aluminum axles and flanged PTFE bushings for smooth operation and excellent durability
• Pedal to saddle distance remains nearly constant through travel
