So i have recently got back into cycling and have been building a bike. I have purchased the campagnolo Athena groupset, only the cranks are campagnolo overtorque not Athena. What choice do i have in terms of compatability with chainrings. Do i have to stick to Athena or can i get super record etc ? Im not sure if the over torque crankset came with its own specific over torque chainring ? Many thanks guys

It isn’t important that the chainrings are the same groupset as the cranks, but they must have the correct number of holes (!) and the same bolt circle diameter. But be careful: this does not mean that all Campag chainrings will fit as standards have changed over the years. As an alternative, TA make compatible chainrings, which can be useful if you want a non-standard number of teeth.

Thanks i got a cracked ng deal with them, think i paid 100£ brand new old stock. Cant imagine things have changed that drastically in 5 years. How important is it that it is the same as my groupset i.e Athena or will any campagnone be okay to use ? Thanks

Nice crankset btw.
