The Thudbuster G4 is superior to its predecessor in every way. Building on Thudbuster’s proven parallel linkage technology we have completely re-designed the seatpost for increased durability and additional suspension travel, as well as ease of use through tool-free elastomer change and a single-bolt seat clamp design.
- Maximum suspension: 90mm of travel (3.54in) for maximum shock absorption while cycling.
- Reduce riding pain & increase comfort: Absorb bumps, dips, and drops. Soften your ride and make biking more comfortable and enjoyable so you can ride longer.
- High quality & durable: Completely redesigned from the previous model for increased durability and additional suspension travel.
- No shop tools needed: Tool-free elastomer change and a single-bolt seat clamp design for easy seatpost adjustments.
