Dirt Jump MTB Forks

Massive airs, big jumps and enormous tricks need MTB Fforks which can take some punishment forks not designed for this reason are liable to be damaged or worse break ; causing heavy injury to a rider.

A dirt jump ( DJ ) bike will typically be a hardtail and front suspension, although some riders do still favor firm forks. Dirt jump forks will have little travel of 80-100mm and are routinely coil sprung as well as being much heavier thanks to the increased strength than those designed for other trail bicycle disciplines.

If you know anything about dirt jumping you’ll know the name Marzocchi possibly the famous and most widely used type of forks on dirt jump bikes with their infamous dirt jumper range.

The dirt jumper range starts with the entry level DJ3 fork. It’s a quick-release fork, but the straightforward forged lowers are very well proven re slam proofing. The coil-sprung internals get a straightforward but effective bottom out damper for slam control. They may also be stiffened up for emergency-only movement ( if that is’s what you’re after ) by charging the auxiliary air spring.
The range then moves up to the Dirt Jumper 1 & two models, which, in the just asserted 2010 models will utilize the updated Open Bath RV damper, which features externally adjustable rebound damping. The Dirt Jumper one & 2 models feature a coil spring and a low pressure pre-load system.

Weighing in at only 2240g for an open bath, coil sprung fork the DJ1 weighs a massive 355g less than the 2009 DJ1 while increasing strength by 30 percent.

If you can not spring the £190 £500 ( $200 – $1000 ) that the dirt jumper range can cost may need to instead consider a rigid fork. The advantages are not only cost, firm forks such as the Charge Nozzle will not only cost less but will also weight a lot less than suspension forks meaning you can save additional weight which may assist you with getting some of those technical tricks nailed.
