Pick up North LDN (I'm N7) preferred
Crankset : Ideally Sram rival or up, chainring 36-42/ otherwise I will replace.
Saddle: Would like a fabric line shallow, but open to others if reasonably priced (<30) and black
Seatpost Black S27.2, doesn't need to have loads of length, say 300?, Ritchey WCS would be smashing but again not super fussy. realistically looking at alloy rather than carbon unless it's a bargain.
