Spokes pinging?

JesseD

I have a set of DT Swiss RRC65 Dicut carbon clinchers which are approx 4 months old or thereabouts.

Recently (over the past 2-3 months) I am getting a pinging noise coming from the spokes when riding, its more prominent when I first start riding then after about 5-10 minutes it seems to stop, then intermittently comes back when riding at slow speeds?

The tension on the wheels seems fine, they run true and have not had any knocks or anything?

What is this a sign of?

Pinging is usually experienced with new-build wheels that haven't been de-stressed and as you ride along the wound-up spokes torsionally relieve themselves when the rim is under compression. It's unusual to be happening all the time, particularly as DT Swiss use locking nipples that don't generally work themselves loose. It could be that the wheel is flexing under load? I would get the dealer to check them out under warranty

Cheers Monty Dog.

After I posted this I contacted Madison who put me in contact with the warranty guys for DT Swiss, I have pinged them an email asking what to do and I suspect they will want them in for examination.

Its really strange as the wheels are used daily so should be bedded in by now, they run true and the spoke tension seems fine (checked by me and my LBS), still it shouldn't happen and whilst they are under warranty I need to get it sorted.

When it comes to DT Swiss wheels, nothing is strange. IME their builds are shocking

Try a drop of lube where the DS spokes cross and touch each other. Ive had Neutrons that ping and that cured it.
