Is that 1" longer or 1" shorter? What about top tube height? Head Tube length?

You should be able to find a stem that is about 25mm shorter or longer than what you are currently using. But, as Iride01 mentions, you may also be able to adapt to slightly different positions. Perhaps favoring being stretched out over being too short (don't want the knees to get in the ways of the bars).

You should have a little vertical adjustment with your stem adapter.
