I have a pinarello marvel frame which has pf30 bb . I want to install campag chourus group , but have read bad things about creaking from the crank/cups ? I have read about the praxis works converter which could solve this ? Any advice welcome

    This comprehensive chart from C-Bear gives you the options they offer by way of convertors

    https://www.c-bear.com/bbchart.pdf

    Would appear that they have a couple of options for Campag UT cranksets (think Chorus is UT rather than PT) and PF30 BB's. One has an R-suffix and the other a C-suffix - Not sure what the differences are but a call to C-Bear would sort you out.

    Chorus is UT and R denotes Road (C is for Cyclocross)

    Praxis campag adapter is the same one for PF30 as BB30. It works just fine with UT. Once fitted, which is easy, you basically have the equivalent of press fit cups installed and can assemble the crankset.

    I use this, and know others that do. I never even bothered with campag's own press fit cups as I knew there was potential of creaking, and with the praxis everything has been silent for a good few thousand miles on that particular bike.

    Here it is https://www.praxiscycles.com/product/conv-bb-campagnolo/ there's a video on that page to show fitting it on BB30 or PF30.
