We met the owner of Wren forks at Interbike and were truly impressed with this local American company.

We think this is the best Fat Suspension Fork on the market.

The Wren Aluminum Fat Bike Suspension Fork continues to set the standard  as being the “Bluto Killer” now with the added feature of Keyed Stanchions.  Similar to the design of a motorcycle fork, the keyed stanchions prevent stanchion twist and keep you running true.  The Wren inverted design puts the 36mm stanchions on the bottom reducing the lower mass of the fork making it more responsive to the trail. The beefed up crown and 43mm uppers provide the strength and torsional rigidity. All Wren suspension forks have fully adjustable rebound and compression on the oil side. In addition, the Wren fork has a rider accessible dial to make compression adjustments on the fly including lockout. The new TwinAir  spring allows for quick and easy pressure changes to keep you fine tuned for the trail. And all TwinAir forks now come with carbon bash guards with carbon clamps, 2 travel clips and 2 hose/cable guides! Attention snow riders – this fork works in the cold. Get your freeze on!
