Ok, haven't found it here, my google-fu is weak, or what I am looking for just doesn't exist ATM.

I am looking for the following chainring that is:-
1) 130 BCD, 5 bolt (to fit a DuraAce SRM 7900 crank).
2) 56 tooth (not 55, not 57, and definitely not 58).
3) 10/11 speed.
4) Aero.
5) Light (duh).

The MDT ones fit the bill perfectly, but they aren't being made any more.

Any others out there?

They fit the bill, 100%, though I am having trouble finding any for sale in a less-than-dodgy-source. If you or any one else knows of a reputable online store that has them that would be awesome :thumbup:

Ding ding. Looks like a winner. Found two places that have it in stock too.

Happy to look into any other suggestions but the Stronglight looks the goods.
Cheers!

Website not great but the guy behind it knows his stuff, and works with Magnus Backstedt and Sarah Storey on the designs.

More robust than fibrelyte and can CNC to order.

Fiberlyte? They can custom a carbon chainring for you in any shape. Not sure about durability though.
