For a laugh and to use up some spare parts I've ordered the R7 10-speed rim brake, mechanical groupset in the 2024 version.
Having used a variety of Campag groupsets in the past it will be interesting to see how this feels in comparison.
65 USD on AliExpress for shifters, FD and RD - certainly pretty cheap. Shame that the newer FD (with the tension adjusting screw) and RD (shadow style) don't seem to be available on AliExpress yet but maybe that's a later upgrade.
