It also sounds like the damper fluid could be aerated. Therefore you need to get a damper service done by a reputable shop or suspension service center.

that's definitely what that sound is.

Hi I'm looking to replace the air shaft assembly on my 2016 Fox 34 27.5+. I am trying to decrease the travel to 120mm. The fox part number that I need is 820-02-401-KIT according to the fox manual. I cannot find that part online.

My question is, are any of the newer air shaft assemblies compatible? I saw that they are still using the NA2 air shaft on the new 34's.

Thank you!

Hi is it worth it to replace my air shock for a coil shock on my old géométrie bike: 2013 stumpjumper evo

No, for three reasons:

1. Unless the shock is in poor condition, the money would be better put toward a new bike, eventually. If the shock is in poor condition, then a new shock isn't a bad idea, but get a very cheap one.

2. That bikes requires a shock with a proprietary mount, so your options are extremely limited. You may be able to find a stock shock on sale for about the same price as a full service on your current shock.

3. The motion ratio curve of that bike is poorly suited to a coil.

True. I'm hesitant to recommend putting more money into the bike, though a BikeYoke and heavily discounted shock (with air spring) wouldn't be too expensive and could keep the bike going for another couple of years.

couldnt you just use spacers to lower it and then adjust oil levels in the damper to what a 120mm fork would run?

I am not sure. What I saw on youtube was to get a new air shaft. Fox makes the specific 120 air shaft but i cannot find it for sale anywhere l.

You are correct - you need the air shaft to lower your travel. Have you tried having your lbs order the shaft from Fox?

Cool figured it would be like a RS fork where you could throw spacers in there

Yesterday the Norco branded hub of my 2018 125 went from loud, to almost silent to “catching” and making some really terrible noises. For the most part, the pawls catch when pedalling forward and spins freely when pedalling stops, but every once and a while, the freehub no longer spins freely. Obviously somethings going on and I want to pull things apart and take a look, but after pulling the cones off, the freehub body and axle are still solidly in place.

Any tips for pulling out the axle and/or pulling out the freehub body?

Thread the nut on one end of the axle. Then use a appropriate size socket and hammer. tap the axle out of the hub. The freehub may require a 12mm or so Allen key
