Mystery solved....

[(Deon)]

Here....

 

 

Well done, must have taken ages to get the arrow to balance..

I have a similar problem. A vibrating/grinding feeling/noise that I can't find. Can't afford a new bike so I have learnt to live with it...

my man that can only be worn out bearings in you're suspension pivots .... replace

[ThePubSA]

I also have the exact same problem on my trance

 

Sounds like my trance

[goya-goya]

creeeeking noises when force is applied...

 

Steps I take:

1. Pedals - take them out... clean screw and the hole in the crank... put some grease on the bottom half of the screw and some loctite on the deepest end of the crank hole... screw in...
   
2. Chain - clean and keep clean... make sure it is lubed after cleaning... spin the cranks a while... then wait a few minutes and wipe the sucker clean - the lube is already where it should be the other stuff will just attract dust which will squeal
   
3. deraileur hanger - grease and loctite
   
4. rear deraileur - keep all moving parts lubed... one squirt of any lite spray lube... then wipe off excess
   
5. Saddle - spray some lube on the connection parts with the seat post and wipe off excess
   
6. Seat post... use carbon paste
   
7. BB - use same process as pedals... fasten correctly
   
8. crank - use same process as pedals... make sure it is fastened correctly...
   
9. if you are smart and have a dual suspension... do the same with the pivots
   

if you still have a noise it could be that your cassette is not fastened...

if you still have a noise... you could have tinnitus!

Me too, mine turned out to be my knees.

 

Have you got a nipple on your knees????????

 

........Q20 is not a lubricant

What do you call Q20 then ?

What do you call Q20 then ?

 

Q20 is rated as a light lubricant or penetrating oil. It will not protect or give lubrication to a hard working component. It also works as an exellent degreaser.

 

Take a new chain and lubricate it with Q20 only, every time and see how long it stays lubricated into your ride.

 

The noise the OP complained about was most likely removed by the blast of compressed air and the penetration of the cut back oil. It will most likely not be a lasting solution. I am not sure what the manufacturers manual says but I am sure decreasing is not an option. Fortunately you get Q20 in small enough cans to carry in your back pocket.

To all the trance owners... as mentioned above by goya, point # 9, check your suspension linkages. Rust mated a bearing to a linkage on mine and creaked rather loudly when pedaling hard.

This is not a bearing failure vibration/noise. The bike was new when it started. I thought it needed to "bed in". It doesn't happen all the time either. Seems to be an intermittent fault. Hasn't done any damage that I can see so far, I have done a visual inspection to see if I can see anything. The next step will be a strip and rebuild but I am waiting for my shiny new torque wrench to arrive befor I start stripping,,,

Take off the bar clamp on your stem. Put a THIN and EVEN smear of grease on the bar where it clamps.

 

Replace. Tighten bolts to correct torque.

Horses for courses, use it, don't use it, spend a lot of munny on replacing component or use the correct lube and save cash to pay your toll.

I just went through a similar ordeal, as my old road bike was making a horrific knocking/creaking sound during hard pedaling. These sounds appeared to come from the BB. I had already greased the seat post, so the problem seemed to lie elsewhere...stripped the BB, cleaned and regreased bearings, stripped freewheel, stripped front and back wheel hubs, adjusted stem bolts...but alas, the knocking only got worse. I could hardly deal with this creaking on my daily commute, and people could hear the bike long before it appeared. I loved the bike, but frankly, the racket was getting on my nerves, and I couldn't enjoy my riding because of this irritating creak.

 

With nowhere else to turn, I went back to basics. Regreased the seat post (that still had fresh grease on it from the last time). By this time, i had given up hope of riding a relatively silent bicycle again...

 

This morning, I began my commute with a heavy heart, as I knew that as soon as I hit the uphills, the inexplicable creaking would start. However, I made the top of the first hill without so much as a whisper from the BB, or any other part of the bike. Ah, I thought, I didn't pedal hard enough. So the next hill, I gave it stick all the way to the crest, and there was still no creak!

 

I have been creak-free since then! Weeks of knuckle-skinning, cold and greasy nights of toil, all because I just needed more grease on a part I had already greased.
