So. I want to buy an All City. My race bike has stack and reach of 525x380 with a 540mm TT - I have a few spacers and a 90mm stem. I want a Macho Man for commuting. The 52 is 563x378 with a 550mm TT. The shop I'm talking to are saying this will be too large and I should size down. Happy to ride with a 90mm stem. Thoughts?

You can keep the 90mm (the diff is mere 2mm) and get rid of spacers. All city stack might not account for external headset stack. So add stack height of your chosen headset.

Forget about all other dimensions, just stack and reach can determine your reach/bar position.

Yeah. That's what I thought. But this shop keeps nattering on about the TT length, and I'm trying to preach forum wisdom that S&R are king but have now entered the realm of self-doubt.
