32" Wheel Capacity

Yes, all Wren Inverted suspension forks fit 32" wheels. Rocking a 32" wheel on our inverted suspension does require a simple internal tune which reduces the travel by 30mm but maintains the fork's full axle to crown height. This means you can run our suspension with a 32" wheel at 120mm of travel and 80mm of travel depending on which model fork you buy.

These travel reductions are absolutely vital for using 32" wheels safely with our fork. Failure to reduce your fork's travel WILL RESULT IN A VERY BAD TIME, as you will hit the fork's crown with the tire on a big impact.

In our tests, we found that the added rollover benefits of 32" wheels more than made up for the loss in travel when comparing a 29er at 150mm of front suspension vs a 32er at 120mm of front suspension. For what it's worth, we're big fans of big wheels.

The Inverted Design

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 exactly what you want when blasting through your chosen trail!

 

 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 is 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.

 


The Wren All-Weather Damper

Introducing the NEW Wren All-Weather damper. Now standard equipment in all Wren suspension forks. Real-world tested down to -27°F (so far), the Wren All-Weather damper is the only damper you need to ride in all temperatures. Wren dampers are a sealed cartridge unit that prevents contamination and needs no servicing. The sealed unit uses a flexible bladder to keep the oil under pressure at all times greatly reducing the effects of cavitation at high damper speeds. Wren dampers have both compression and rebound circuits and provide a true lockout. Wren All-Weather dampers are maintenance-free ensuring consistent performance over the life of the damper.

 

Keyed Stanchions

Keyed Stanchions keep Wren suspension forks running true and prevent the stanchions from turning. 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.

Damper Side

Not all lockouts are created equal. When our fork is locked out, you'd swear you're riding a rigid fork. Bring on the mixed surface-type adventures!

Good interactive toy that keeps even my poodle mix busy
Color: Blue
We have a poodle mix that easily gets bored with most toys, including the other interactive bouncy balls. This toy seems to keep him busy though and so far he has not destroyed it or grown bored of it. The only problem we have is keeping it charged because he seems to wear it out but it is not a problem to recharge it with the USB cable that is included. It is a little tricky screwing the toy back together after charging the battery but I am getting the hang of it. Once it is set to one of the play modes the ropes on top (that you need to put on) will start spinning back and forth and the toy gyrates around seeming like it is alive to our dog. The loves playing with it in all of the modes but I think he likes that faster modes better. It comes with an extra rope which was good because our raptor dog already ripped the first one apart. The price on this toy is relatively low compared to tother toys to I highly recommend this for anyone that has a dog who is bored with the typical play toys.

Great entertainment for kittens too!
Color: Blue
My kittens love this toy and play with it more than my dog. I bought it on sale. I am impressed with the quality, ease of use, and I rarely need to charge it.

Finally, a Toy That Out-Works My Dog!
Color: Blue
My dog gets bored easily, and this automatic moving ball has been a hilarious and effective distraction. It bounces and rotates on its own, which triggers her hunting instinct immediately. The rope chew attached to the side is a nice touch for some added teeth cleaning while she plays. It’s sturdy enough for a medium-sized dog and the fact that it's waterproof means I don't have to worry when she eventually drops it in the water bowl or takes it out into the melting snow. The *only* issue I have is it starts before I can even screw it back together. It wants to jump out of my hands before I'm ready.
