Clicking sound when rear suspension decompresses...help ID cause

[carvegybe]

Happens when not pedaling as well. I tightened linkage bolts to 137.5 in/LBS and shock bolts to 90 in/LBS. The clicks are quite loud.

Also, the bike is clean.

Any thoughts?

Thanks

Chainring.

Actually seat?

Comes from lower part of bike, BB / shock area...

Shock bushings? Hold the bushings while compressing the suspension, sometimes you can feel them move even if you can't see it.

Shock bushings?

Maybe. How would I know? Trip to LBS or is there an easier way to tell?

see edit above.

LBS time I think...can't find the cause. Thanks anyway.

doesnt matter where it seems to come from noises travel in weird ways through bike frames.

Unbolt the shock and see if the bushings have play in them. While the shock is off cycle the pivots to see if there’s any binding

I have never unbolted a shock. I guess it's time to learn. Anything I should know before I do this?

You know this while on the bike?
Or inl? Independent noise listener.

Measure the pressure and then take the air out of the shock.

I did a funny thing at home sitting on the bike and listening for source of clicks by doing some odd form of torso rotation...definitely lower that saddle / seatpost.

Which shock? I've found some noisy and just the way they work.

There are so many things it could be. Could be a loose thru axle, or cassette, pedals. On a carbon bike, the sounds will travel and come from weird places. Usually it's not anywhere near where the sound is coming from.

Unless it's a cracked frame.

It’s a clapped out Raceface Chester or atleast it was for me.

I thought this was solved a while back over in the chainring thread ?

Rule out the seatpost/saddle first:
-Grab seat/seatpost by the front of the saddle and push it around with lots of force to try to determine if it's coming from there. Seatpost/Saddle is probably the most likely spot.
-Bounce up and down while on the pedals but NOT on the saddle to see if if the clicking happens when you're not on the saddle.

If the noise isn't there when you forcibly move the saddle and still there when bouncing off the saddle, remove the shock and see if everything moves well.

It really could be anything. Suspension bearings, wheel bearings, loose axle, headset, bottom bracket, etc etc etc.
