WREN Inverted Mountain bike Suspension Fork

Advanced Inverted Design

Our inverted fork design is engineered for superior performance on the trails. By flipping the fork and placing the lighter stanchions at the bottom, we've effectively reduced the moving part's mass, ensuring quicker and more responsive reactions to the terrain.

This design also securely anchors the stanchions into the stronger upper tubes and crown, bolstering the chassis's overall strength and stiffness. Lowering the fulcrum point where the uppers join the stanchions diminishes the leverage factor, enhancing control.

Additionally, the downward positioning of the seals prevents debris from compromising the fork's functionality. Experience the agility and strength you need for challenging trails!

Wren TwinAir System

The Wren TwinAir System revolutionizes fork tuning with unparalleled simplicity. Unlike traditional token systems, our TwinAir system offers infinite adjustability without requiring fork disassembly.

By adjusting the floating piston, you can fine-tune the spring rate to match your riding style and trail conditions precisely. The system divides the air chamber into top and bottom halves, each with individual air valves.

Whether you prefer a plush or progressive feel, the TwinAir system puts you in control. With the ability to adjust on the trail using your shock pump, fine-tuning your ride has never been easier.

Wren All-Weather Damper

Introducing the NEW Wren All-Weather damper, now a standard feature in all Wren suspension forks.

Tested in real-world conditions down to -27°F, our damper ensures reliable performance in any temperature. Sealed to prevent contamination, it requires no servicing and maintains oil pressure using a flexible bladder, minimizing cavitation effects at high speeds. Equipped with compression and rebound circuits, along with a true lockout.

Wren All-Weather dampers guarantee maintenance-free, consistent performance over their lifespan.

Keyed Stanchions

Our keyed stanchions keep Wren suspension forks aligned and prevent stanchion rotation. The 43mm uppers feature channels that accept brass keys, perfectly aligning with oversize 36mm stanchions.

Designed to shear under extreme impact, these keys protect the channels and your fork from damage while ensuring continued functionality. Easily replaceable, they ensure the fork remains operational even after significant impacts.

Damper Side

Not all lockouts are created equal. When our fork is locked out, you'll feel like you're riding a rigid fork. Prepare for mixed surface adventures with unmatched confidence.
