9 speed Tiagra, mid 2000s is the best shifting system I've ever used. Good choice. Newer Tiagra FDs, like 2020, shift better than older; but 2007 Tiagra RD shifting is superb, and the levers and hoods are just the right size and beautifully finished. Also cables that are not under bar tape are easy to change and adjust on the fly in the rare instance you'd need to.
