Rotor 3d30 crankset 172.5mm

Selling this stiff and straight-armed Rotor 3d30 crankset, 110 semi and compact spider.
This has been barely used and it shows. The condition is superb, some small marks but no major scratches, the spindle is in great condition. Logos are a bit faded but no rub.

I would like 100£ picked up postage on top

thanks !

what BCD on that spider?

of course, it is 110

This is probably a dumb question but what BB size is this for?

rotor also do 24 but this is 30mm

Got a bit confused with Rotor's universal compatibility; this should fit a standard 68mm english threaded bb right?

It will, only if you buy the Rotor BSA 30 bb.

I stand corrected but this seems to be the threaded cups for this https://www.sigmasports.com/item/Rotor/BSA-Bottom-Bracket-to-BB30-Steel-BSA/10QE?utm_source=google&utm_medium=base&utm_campaign=base&co=GBR&cu=GBP&glCountry=GB&gclid=EAIaIQobChMI4Yu4iJfb2gIVGYXVCh0ITQ_4EAQYAyABEgK9TfD_BwE&gclsrc=aw.ds
