CaneCreek Thudbuster ST G4 review

How much can a suspension seat post add in the era of wide tyres and comfort geometry? A lot, it seems

CaneCreek Thudbuster ST G4
Cycling Weekly Verdict

I’ve been pleasantly surprised how things have moved forward since I last sat on a suspension post more than 10 years ago, going from a bouncy castle to a controlled, compliant, tool free adjustable system that will appeal to many riders. If you’re a commuter, e-bike owner, bike packer, weekend adventure rider, or a bike is your main/only form of transport, and you want to add some affordable compliance and comfort to your steed, then the Thudbuster ST is something you should seriously consider.

This is CaneCreek's 4th generation Thudbuster ST (Short Travel) suspension seat post. It's been met with plenty of glowing reports, so I was keen to understand what all the fuss was about.

Suspension seat posts aren’t a new concept, but when the opportunity to test the Thudbuster came up, I couldn't help but reminisce about the days I owned an original USE Shokpost some 12 years ago, and was keen to understand how far the tech has brought us and what the advantages of running a suspension seatpost might be in the current era of wider tyres and optimized comfort geometry.
