What I'm gathering from the responses is that it matters. And that 70mm is more unusual rather than common.

The old bike was a 4.3 Domane, new one an SLR7. I'm not short at all, being 5'9. Now I'm wondering if the LBS really wasn't all that swift on this task last year. The fit was more informal, rather than hours long and I assumed the guy knew his stuff. Maybe not!

I'm mostly okay on the bike as it is. Actually one of my concerns was if we shortened the stem, that now may put more pressure on the hands.

The point of the question was that I thought I would be duplicating whatever had worked last year. Now I'm not so sure and will think the solution.

Thanks...
