What the heck is that noise from the TT bikes?

As above.

What makes that noise like a slow turning helicopter blade on TT bikes?

I'm guessing it's the wheels, but which bit?

Carbon disc wheel.

It's why we buy them. Not cause they make us go faster but for the noise.

Thought it was the electric motor

Get yourself down to a TT and fill your boots. The sound is amazing in real life but not so amazing if you are racing and you hear one as it means you've been caught!

Or you've caught the rider in front!

This happens to me (fairly often) it always reminds me of the noise the Tardis makes!

I remember some of the elite guys passing me in the first triathlon I did. I thought I was being overtaken by a wing of Tie Fighters to start with, quite unsettling! 8)

Very unlikely for me in a TT, different matter at a triathlon though

I've never seen people using solid disc wheels in a triathlon – but I deep section rims have a similar sound, if a bit less hollow sounding. The noise can be useful guage of how hard someone just behind you is riding, i.e. if they are winding up to attack on a climb.
