150-160mm/ Enduro
FAST . BASTARD . DOG
Meet the Chilli Dog, our long-travel steel hardtail built for riders who think suspension is optional but sending it is not. This thing is packing 29-inch wheels, 150–160mm travel, and enough attitude to make your full-suspension mates question their life choices.
Cooked up in the very same factory kitchen as our steel Grim Ripper—but with tubing tuned specifically for the Chilli Dog’s desired flavour profile: tough as fuck, but somehow still supple in all the right places. Like a steel sledgehammer that gives great hugs.
This is the hardtail you buy when you want:
-
Big wheels to roll over anything (including your own excuses)
-
Big travel because subtlety is overrated
-
Big sends and bigger consequences (that it somehow absorbs anyway)
The Chilli Dog doesn’t care about your Strava time, your KOM dreams, or your chiropractor’s warnings. It’s here for violence, velocity, and very poor decision-making executed with incredible style.
Steel is real. And this steel is ready to ruin trails, egos, and any idea that a hardtail can’t go toe-to-toe with enduro big dogs (And usually win. Because it’s funnier that way).
Long travel. Long legs. Long list of things it’ll happily hurl you off.

''It took me faster off road than I have likely done on a hardtail in a long time...''

Sizing
Struggling with what reach to choose? Why not check out our sizing chart...
The frames have short seat tubes with a very low standover, so sizing is very flexible and more centred around the length. We recommend the use of longer dropper posts and shorter stems (35-50mm) dependant on sizing.
(See geo charts for cm measurements)
Regular: 5ft5 to 5ft11
Uber Long: 5ft11 to 6ft4
This is our GUIDE and how we would recommend the sizing. This is certainly not a definitive recommendation, so riders should choose to how they prefer their bike!
Are you on the lower end of a scale? Not a problem; thanks to the short seat tubes and lower standover this is not a problem.
Sizing up, or on the shorter end of the scale? shorter dropper post/35mm stem
Sizing down, or on the larger end of the scale? Longer dropper post/ 50mm stem.
Seat post insertion depths
Short, straight seat tubes allow for most 200mm droppers to be fully inserted. See max seat post insertions;
Regular: 290mm
Long: 310mm
