Cross Country (XC) Suspension Forks
Light and short travel, XC mtb forks are usually single crown due to the mild terrain and to save weight so not to make the bike too heavy to rise.
Traditionally, XC forks will have been spring loaded however the trend is now moving towards air sprung suspension.
The obvious advantages of such a change of keeping the weight of the fork to a minimum and making them simple to adjust this.
Downhill (DH) Suspension Forks
Have you ever observed the insanity that may be downhill mountain biking? Massive drops, giant gap jumps and terrible terrain over a short prtiod of time. Downhill forks can have large amounts of travel ( 10 inches isn’t unhead of ) to allow for the stress a DH bike is put under.
Downhill forks are usually coil spring to take on large hits but are also double crowns ; this is where there are 2 legs of the fork close to the top where the fork joins the handle bar. Double crown forks offer double the suspension of single crown forks.
Dirt Jump (DJ) Suspension Forks
Big airs, big jumps and big tricks require forks which can take some punishment forks not designed for this reason are responsible to be damaged, or worse break, causing heavy injury to a rider.
A dirt jump ( DJ ) bike will sometimes be a hardtail and front suspension, though some riders do still prefer firm forks. Suspension forks will have small travel of 80-100mm and are normally coil sprung as well as being much heavier thanks to the increased strength than those designed for other off-road bike disciplines.
Rigid Forks
Although suspension forks are far more and more a standard sight on trail bikes they are by no means the only option left.
For the die hards, people who don’t wish to invest in pricey suspension or those preferring something lower maintenance there remain a number of quality stiff forks available on the market.
extremely popular in the dirt jump and street MTB scenes as well as singletrack, rigid Forks supply a viable and often less expensive alternative choice to suspension.
