Grim Ripper STEEL — The Cult Classic of Chaos

The Grim Ripper STEEL isn’t here to babysit you. It’s here to egg you on, shout “SEND IT!” in your ear, and cackle as you overshoot the landing.

Handcrafted from steel (because it’s real, obviously), this thing is SO unhinged, it can run ALL wheel sizes from the SAME frame!!

  • Short-mid travel 29er/Mullet for speed demons who like it snappy, poppy, and just twitchy enough to keep things spicy.

  • Long travel 27.5 for full-gremlin mode — big hits, sketchier lines, and absolutely no chill.

It’s built to ride hard, go fast, and survive whatever trail tantrum you throw at it. Steel gives you that planted, buttery feel with a side of “oops, that was a bit much” forgiveness. Perfect for riders who love the raw, rowdy stuff but still want something that’ll outlive their knees.

No flex, no fluff, no unnecessary nonsense. Just a proper good hardtail that wants to party

 

RUN IT YOUR WAY....

Steamer: Run a full 27.5 set up - 150mm to 160mm travel

Big Roller: Run a fast rolling 29er - 130mm to 140mm travel

MULLET: Business up front, party in the rear. The best of both worlds.....  - 120-130mm travel

''The more compliant back end of the Grim Ripper seemingly smoothing out the rough in a manner I was unfamiliar with on a hardtail...''

Sizing

Struggling with what reach to choose? 

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

 

Seat post insertion depths 

Short, straight seat tubes allow for most 200mm droppers to be fully inserted. See max seat post insertions;

Regular: 300mm

Uber Long: 320mm
