First time I've had carbon(part) wheels. They ride ok but seem a bit twangy. I even thought I might have a loose spoke but can't identify one. I guess there's some echo from the carbon bit.
Oh and really I'm only talking about the back wheel

Oh and another thing......really hard work in the strong crosswinds today.
Anyone else?

Mine are silent. Have you checked spoke tension?

If they are making a twanging noise that would suggest the spokes haven't been stress relieved properly. what wheels are they??

Don't panic, new wheels often twang for a while as the spokes settle in and rub against each other. If it's still doing it after 100 miles then investigate.

Are you using valve extenders as they can rattle a bit. I wrapped mine in tape and the wheel is quiet now.

Cheers
Im not using extenders...bought new tubes
My 23c tyres were a bit of a stretch on these slightly wider rims,quite hard to get on in fact but seem ok once inflated.
It never occurred to me that the clinchers would have a wider rim.
The noise is ok on smooth Tarmac but when under pedalling load whilst going over rough surfaces they just seem to chatter a bit??

Valve extender or long valve- either can chatter against the inside of the hole in which they sit, although it's more usually a "tonk" every revolution of the wheel.

i cut a small circle of helicopter tape, pierced it in the centre and pulled it down over the valve, it's now totally silent.

The spokes, will "tinkle" for the first few hundred metres when the wheels are brand new as they find the position they want to be in with a riders weight on them, but should be silent after that.

A lot of carbon rims will rumble, or sing, depending on tyre pressure and road surface - my Zipps rumbled so much my club-mates kept thinking it was a car coming up behind them, for instance.

Give them a few miles then if the noise strikes you as something you are unhappy about take the bike into a good LBS.

Just been out. Much quieter today. Gave them a prod and a poke before I went.
These are the ones by the way

If they're from ecsgolf on eBay then I'm sure they're the same as the PX clinchers, which are always a bit 'clattery'.

That saddle needs to come down, forward, and be levelled up a lot - and if you have it like that to reduce pressure on your gooch then you need one of these:

They look good, they suit the bike.

Yep from the chap on eBay
Collected in person,really nice family and has lots of Planet X stuff through a business connection. I was going to get their clinchers since I'm only 10 miles from PX headquarters but figured these looked as good/bad lol and I saved some cash.

As for the saddle it doesn't seem to look quite so angled in real life,although camera never lies etc. as said I've got used to it but I'm prepared to tweak it and see if it's better although I'm not sure about the being further forward bit but I'm always open to try stuff..
