Theoretical question: A frame builder makes frames
in even sizes; you are interested in a 60cm or a 62cm.
After studying the respective geometries and comparing
them with what you have ridden in the past, you decide
a 61cm would be best. However, builder doesn't offer a
61 and you can't afford a custom build (don't even want
to discuss it). Would you go a size up or a size down?

(And, to the pundits who would say: "Ride them both" you
have to say" "Impossible to do in this town".)

So, who would go with 62cm & who with 60? & why?

Thanks. Ken

For seatpost exposure 3/8" doesn't really matter that much--that's the
difference between 61 and 62.

Pick the frame that fits best out of the two. Maybe you need the 62
because oyu have a long torso. Maybe you'd rather have the 60 becasue
you have a short torso. (Bigger frames tend to have longer top tubes).

So look at the fit aspects other than seatpost.
