Click/pop coming from new front wheel...?(7 posts)

Click/pop coming from new front wheel...?MrDan
Jun 26, 2003 8:28 PM
I've been riding a new set of wheels for a couple months. CC built them - CXP 33's. These things are great, have held their true, and definately good mojo on them.
Problem is, on last nights ride I began hearing a popping/clicking type thing, and it syncs with wheel speed.
I checked the spokes and pinged each spoke to try and find a loos one - to no avail. Also checked the bearing adjustment and found that the play disappears just before the skewer is closed all the way down. I also checked my cranks and tried tweaking them tighter, but they felt fine but still this clicking sound is driving me nuts...
Any ideas?

Before the extrusion is bent into a hoop, it has locating pins tack welded onto one end. The rim is then welded and machined for strength to complete the manufacturing process. Sometimes these locating pins break off and float in the hollow of the box extrusion.

What can be done is put a dollop of silicone sealant into a spoke nipple hole from the tire side near the welded seam. Slowly spin the wheel in attempt to get the pin to stck to the goo.

Try insulating the rim from the valve stem. Slipping a short section of drinking straw over the stem can work well.
Have you checked...Mootsie

I agree with Atombomber. Mavic is notorious for have the pin come loose. I've had to have my rim fixed at my LBS. Did you also check to make sure that its not the computer that you are hearing? I get a little ticking sound when the magnet on the spoke crosses in front of the pick-up on the fork.
Thanks ladies and gents!MrDan

Thanks all, for the advice. I'll try and track it down before Saturdays ride! Happy riding - now that the monsoon season "seems" to be over here in Mass.

Try a drop of oil on each nipple where it enters the rim.
Update: It was under-tensioned spokes... and questionMrDan

I checked the spokes again by actually pushing on them. There were a few with MUCH less tension on them, so gave those a 1/4 turn each tighter and the "pop" has disappeared.
Now I'm just worried these wheels were not made well at all... Their true and round as anything though. Should I ride them for a while and see how it goes, or make a concerted effort to even-up the spoke tension?
