|Cracking noise from Ksyrium SL||Derrick VL|
Aug 25, 2003 7:36 AM
|When I'm standing on my pedals, and accelerate, the back wheel (Ksyrium SSC SL 2003) produces a cracking noice. I tried to lubricate here and there (it's difficult to say where the noice comes from). The noice disappears but is back 75 miles later.
Who can help me?

|I have had ksyriums ssc sl's crack and creak on me.
I put tri flow in the area it creaks and it comes back.
Find the area.Probally where the hub and spokes meet.
Get a good metal based lube.I used moly-coat from Honda.
It is a metalic paste that is spread on the brake pads to dampen the vibrations that causes squeel noise when braking.
I think if you when to a Auto Zone you could pick up a jar of Anti-Seize.It is a silver paste made by Perma-tex.
Remove the hub caps(not on rear) and use the brush to work the mixture into the ball of the tip of spokes in the hub area.
I used compressed air to blow it in there really good.
The noise has been gone now for hundred of miles!
My noise was coming from the front hub when my weight was over the wheel-esp. while climbing.
The aluminum spokes rubbing the aluminum hubs are just noisy and shoud be lubed at the factory!But they are not.
Now you have to do it.

|You also can try aligning the spoke blades ensuring there's no spoke wind-up. My theory is since the hub contact is self centering the spokes tend to pull and rotate against the wind-up under load thereby causing the friction noises.|

|Had the same problem. Greased the skewers (especially in the fork dropouts) and the noise went away. I hade loud noises when standing or sprinting. Sounded like the bike was going to break.|

|I think Anzoni is right. Its the fact that the ends of the front hub that mate against the fork dropouts are finished smooth. The outside skewer end has the usual ridged pattern that bites into the soft aluminum dropouts on the outside, but the hub end on the inside is completely smooth and shifts against the dropout under load causing all kinds of awefull noise.
I just tightend the quick release up and it has mostly gone away except for very heavy loads on all out sprints or climbs. I think the grease idea is even better though since tightening it up is not really what you want to do.
What I can't believe is this is an obvious design flaw and one you certainly wouldn't expect on such a pricey wheelset.
