New Carbone SL front wheel creaking noise under load
I've just bought a set of Carbone SL wheels with Continental GP4000s tyres (inflated to 110 psi). Just the ticket for club racing and time trialling. I notice that when up on the pedals to accelerate heavily (bike swinging from side to side), there is a creaking noise coming from the front wheel. When I don't accelerate as hard (i.e. not swinging from side to side), the noise almost disappears.
When sat in the saddle, there is no such noise, apart from the nice 'whoosh' of course . I weigh just under 87 kilos - could this be a contributing factor?
Is this noise normal or should I take the wheels back to the shop? I examined the wheels and I couldn't see any damage at all (rim sidewall, spokes, hub or carbon fairing).
Appreciate any and all comments from the community.
