Tiagra 4700 parts wanted

jameses

Hi all,
I'm after a couple of parts for an upgrade to my commuter - light use / few marks are okay, but nothing super worn or beaten up please!

Tiagra 4700 or fc-rs510 chainset (50/34 chainrings, 172.5mm crank length)
4700 series front derailleur

Thanks,
James

Should mention, the front derailleur is for a double setup and can be either braze on or 31.8mm band on
