All my bikes are 52cm, recommended by pro bike fitter and Trek’s in-store bike fitting camera/device.

I am looking for a bike to permanently mount to my indoor smart trainer and have found a 54cm that otherwise meets all my criteria.

I if lower the seat to a proper height and install a shorter stem, would the larger frame be an ergonomic fit? Peddle crank length may be “off” but I don’t know what else would compromise a proper fit.

Thoughts?
