PRO DIRT JUMP POST WELD HEAT TREATED
We have modified the 898 to a Taper type headtube to keep in line with the latest forks. The taper headtube makes for a stronger fork and a stronger frame with hardly any extra weight - a good thing for a jump bike!
Limited run of 50 frames with a Euro bottom bracket and 69.5 degree head angle.
Tubeset – custom butted tubing is made from a special steel alloy which after heat treatment is about 40% stronger allowing thinner thickness to reduce weight.
CNC machined head tube to exactly control wall thickness so the strength: weight ratio is optimised & to ensure perfect fit for the Tapered Integrated Headsets
Chainstays – are as short as possible for quick handling and easy manuals.
10mm dropouts are CNC machined to save more weight.
Euro Bottom Bracket for a more versatile choice of cranksets.
Dirt jump Geometry – DMR gets it right, our frames are fine tuned for serious riding and are world renowned for their perfect trail manners – just like our riders!
Light but not too light… there is a fine line between a light bike and a bent bike, our new competition DJ frame has the balance of weight vs. reliability our team riders need, its not a frame for the trail novice though…better stick with the Drone for now.
What Forks? Our geometry is designed for a short travel fork – max 100mm – or our rigid Trailblade forks.
Available in 26” only Grey Metallic or Jet Black includes extra graphics stickers
