Choosing the right fork

Virtually all modern mountain bikes use 1 1/8" threadless forks, stems, and headsets. Before ordering a new suspension fork, be certain that your frame will accomodate the fork you plan to order. Additionally, if your bike has an older threaded style stem and headset, you'll need to swap your stem and headset for a threadless model in order to achieve compatibility with current forks.

In a threadless configuration, (Fig. 1) the forks steerer tube (represented by the dashed blue line) passes through the headset cups (red in our illustration), through the interior of the headtube, and out the other side. Finally, the stem clamps around the exterior of the fork's steerer.

Note that the "insertion type" stems used with older threaded fork setups are not compatible with threadless forks. Nor are headsets which use a threaded adjustable cup and locknut - you'll need a threadless model.

If you're replacing your existing fork, measure from the base of the crown race to the top of the steerer tube and order a fork whose steerer is at least that long. This measurement is represented in the diagram below by the dotted blue lines.

Consider frame geometry

Before purchasing a fork, carefully consider the geometry of your frame. Unless your frame was designed specifically for a long travel fork, adding a shock with a large amount of travel will dramatically change the handling and geometry of your bike. Consider a fork with less travel.

Similarly, if you already have a frame with a long travel rear suspension setup, you'll want to choose a suitable long travel front fork to complement the rear suspension.

Conventional or thru-axle?

A thru-axle fork provides maximum stiffness and better overall performance for downhill bikes. A conventional axle fork provides compatibility with older wheels and faster wheels changes in the event of a flat. Typically, a thru-axle fork will only be used on a downhill specific bike. Remember that your front hub must match your choice of fork. (Fig. 2)

Brake compatibility

Don't forget to confirm that the fork you're interested in has the appropriate mounts for the brakes you plan to use (Disc, V-brake, cantilever). Some forks have mounts for both styles of brakes, allowing you to upgrade to discs at a later date.
