i want to swap out my current bars/stem on bianchi pista for some thomsons so I can have thomson everything like my MTB.
then I want to use the same thomson setback seatpost on my bianchi mtb for the pista.

i dont know about geometry. the pista is 53cm and the mtb is 17.5. i am 5 ft 8 inch. i ride recreationally anyway so nothing serious.
