The Thudbuster LT G4 is Cane Creek's long-travel suspension seatpost, built to take the edge off rough trail and gravel riding without the maintenance of an air or coil post.

Highlights

  • 90mm of travel on a 4-pivot parallel linkage, so pedal-to-saddle distance stays nearly constant through the stroke
  • Tool-free elastomer swap – Extra Soft, Soft, Firm and Extra Firm sold separately; Medium Firm fitted from the factory
  • Single-bolt seat clamp with angle adjustment
  • Available in 27.2mm, 30.9mm and 31.6mm diameters

Setting it up for your weight

Cane Creek rates the Thudbuster LT G4 to 250lb/113kg rider weight. The fitted Medium Firm elastomer suits a mid-range rider; swap to a softer or firmer elastomer (sold separately) to tune the feel for lighter or heavier riders.

Options

Diameter27.2mm, 30.9mm, 31.6mm

Requires round, alloy saddle rails – it is not compatible with oval or carbon rails, per Cane Creek. Minimum insertion is 146mm; maximum extension is 290mm (27.2mm) or 320mm (30.9mm/31.6mm). Length is 390mm (27.2mm) or 420mm (30.9mm/31.6mm). Check your frame's insertion depth before ordering.

Cane Creek warrants the Thudbuster LT G4 for 1 year from original purchase against manufacturing defects; everyday wear, the elastomer bumper, and incorrect installation aren't covered. For warranty support, return the product to Tune Cycles and we'll manage the claim with Cane Creek's Australian distributor. This is in addition to your rights under the Australian Consumer Law – keep your proof of purchase.
