What year/model of cranks - although the BCD with the 'odd' hidden bolt was consistent for all Ultra/Powertorque cranks, the THICKNESS of the ring also affects fit - basically 2 sorts - cheap(er) and nasty stamped type (usually not polished) and fancier polished and/or machined finish (early Centaur, later Veloce, Athena 11s - it's never simple. What speed drivetrain will you actually be running?

Thanks -- Athena 11s. You have anything not too pricey?

Sorry, haven't got anything to suit Athena in silver at any price, and to be frank you're unlikely to find anything at any price and deffo not cheap 😬

Thanks anyway. Guess I'll look for an after market part like a TA somehwere.

TA are a good choice if you're not a brand snob, last just as well as Campag OG, fit is usually spot on. 11spd less fraught as they had by then standardised on the thickness of the chainrings thankfully, 10spd is the minefield. GLWS(earch)!

Specialties TA seem to be the only people offering Campag compatible 11spd now, the keyword is 'Nerius' which denotes the offset hidden bolt. Can also be used to convert 10spd Centaur, Chorus and Record to 11spd. Sadly now only available in anodised matt black, but I've used these on silver arms and they look OK. Available from SPA Cycles:

For anyone searching, the Specialties TA Nerius 11-speed chain ring does fit Campagnolo Athena 11 speed chainset. Thanks for the tip @retrodicorsa
It has an extra washer (o.5mm) that the vendor says you should fit, but on my set-up it wasn't needed (in fact, it pushed things out of true).

Glad it worked out for you. The extra washer would be needed if your cranks originally had the CNC'd/polished type rings which, funnily enough, are 0.5mm thicker than the lower-end pressed ones 😉.
Pretty much as above -- 5 bolt, in silver.
Thanks
