MY26 G4 Thudbuster ST Seatpost

Cane Creek MY26 G4 Thudbuster ST Seatpost is a short-travel suspension seatpost built for riders who want meaningful comfort on XC, gravel, and all-day bikes without the vague, “bouncy” feel that can come with simpler designs. With 50mm of rearward-biased travel and a patented 4-pivot parallel linkage, it helps smooth sharp hits and washboard while keeping the rider’s pedaling position consistent through the stroke—ideal for staying efficient on mixed surfaces.

Comfort and tuning details that matter on real rides

• 50mm tuned travel - Adds compliance for gravel chatter and trail impacts while staying compact for XC and comfort setups
• 4-pivot parallel linkage with PTFE bushings - Controlled, low-friction movement designed for durability and consistent performance over time
• Nearly constant pedal-to-saddle distance - Parallel motion helps preserve pedaling feel and fit when the post compresses under bumps
• Tool-free inner elastomer changes - 2-piece elastomer system makes it easy to match support to rider weight and ride feel; medium installed, with soft and firm included
• Updated clamp interface - Single-bolt seat clamp with angle adjustment, transitioning to a Set Screw (SS) clamp design for secure setup
• Fit range and rider limit - 100mm minimum extension to 274mm maximum; rated to 330 lb / 150 kg
