Wren Inverted MTB Suspension Fork 110mm Axle

When it comes to "what are the best MTB forks" well the answer in simple, Wren, simple, strong, awesome

The Inverted Design

The Wren Inverted fork design simply works better. By inverting the fork so that the lighter stanchions are on the bottom, we reduce the mass of the moving part of the fork so that it will react quicker and easier to the trail. Inverting also anchors the stanchions into the stronger, larger upper tubes and crown making the overall chassis much stronger and stiffer. Inverting lowers the fulcrum point where the uppers join the stanchions, compared to other fork designs, decreasing the leverage factor. Inverting also positions the seals downward so that all kinds of bad stuff doesn’t sit on them and get pulled into your fork. A strong, stiff, quickly moving fork is especially important for fat bikes where the size and weight of the tires put increased pressure on the fork.

The Wren TwinAir System

The Wren TwinAir System is designed to fine tune the ride of the fork using only your air pump. No disassembly of the fork required. The TwinAir system is similar to the token system used in other suspension forks, but is infinitely more adjustable. Tokens are a fixed size and each one you drop in gives you a jump in the spring rate. The floating piston in the TwinAir system can be moved as little or as much as you want. This allows you to fine tune the spring rate to exactly match your riding style and trail conditions.

The TwinAir system divides the air chamber in half using a floating piston. There are individual air valves for the top and bottom chambers. If you want your ride to be as plush as possible, add air only to the top. If you want a more progressive feel, begin adding air to the bottom. This moves the floating piston up reducing the size of the air chamber. Remember, you have total control over the movement of the floating piston, so fine tuning the air spring is a snap! You can even make adjustments on the trail by caring your shock pump. Try that with a token system.

Keyed Stanchions for exceptional stability

Keyed Stanchions keep Wren suspension forks running true and prevent the stanchions from twisting. The 43mm beefy uppers are channeled to accept brass keys that fit to our oversize 36mm stanchions. The keys perfectly align the stanchions in the uppers and are designed to shear should you take a really big hit. This protects the channels and your fork from damage.  The fork will still function and the keys are easily replaced.
