WTD. Small frame for my son

[Grannygrinder]

I'm looking at buidling up a roadbike for my son as he is putting in the miles now but finds his jump bike hardwork, understandably.
He is about 5'5" now so i'm thinking something around 52cm?
Steel, alloy anything considered

Re:

I have a Giant TCR0 pro compact frame / fork / headset / stem / seatpost in small if interested? It's not getting used so needs a new home. Bit scruffy paintwise though.

Got a small Olmo 'Giro' frame & forks. Let me know if interested and I can measure & get some pics for you.
