BECAUSE WHAT THE F**K IS DOWNCOUNTRY ANYWAY?

the delinquent younger sibling to the Chilli Dog: We took the short travel hardtail platform and cranked up the dials.... The Grim Ripper offers maximum stoke with exceptional flexibility in how it can be built.

The Grim Ripper is our first non-UK fabricated steel hardtail, offering a great performing bike, at a great price. The frame is still fully designed & tested in the UK, and is fabricated from double butted 4130 chromoly steel from our leading ISO certified factory in Tianjin. 

 

RUN IT YOUR WAY....

Full Play: Run a full 27.5 set up (150mm max travel)

Full Gas: Run a fast rolling 29er (130mm max travel)

MULLET: Business up front, party in the rear. The best of both worlds..... 

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

MK2

Rejoice my minions.... the MK2 is here!! And we have made some great change for not just performance, but also a number of quality improvements.

  • All new geometry: Longer fronts and rear ends
  • 29 wheels can now be ran in the shortest chain stay setting
  • Lower top tube lines for improved stand over and clearance
  • Taller stacks
  • More balanced fork lengths to give less geo alteration when swapping between 27.5 or 29 forks
  • Quality improvements to headtube and rear dropouts
  • UDH Dropout

Key Features:

  • Travel range: 120-150mm (130mm Max with 29 wheel/ 150mm max with 27.5)
  • UDH Sliding dropouts give +/- 15mm rear end adjustment; ride it your way.
  • Low slung geometry gives ultimate cornering, stability and braking control.
  • Steep seat tube angle for exceptional technical climbing ability and a shorter, more comfortable/natural seated position. 
  • Short, straight seat tube designed around the use of longer dropper posts to get slammed properly when s**t gets hairy.
  • Top tubes run across the same line on both sizes, offering leading standover clearance. Perfect for sizing flexibility and keeping the frame out of your way!
  • Tall stack, because its just better...
  • A slack head angle with a 120-140mm fork means the bike remains composed and slack, no matter the terrain.
  • Frame treated with an ED coat prior to final paint for improved corrosion resistance
  • Manufactured in Asia - Tianjin
  • 3 year warranty & lifetime crash replacement for the original owner.

MK2 Geo Charts

 

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
