If you have an "ideal bike frame" for your bone-structure, and the fit is measured and 'perfect', then unless you have your body altered... then no, your ideal frame size should not alter.

If you go to a different configuration of bike (eg commuting bike to road race bike... or road bike to track bike) then yes, your frame size may change.

But you may need to change your seat forwards/backwards, or raise /lower your stem (handle bars) and this will alter your position. The simplest way of "lengthening" the bike is a longer stem.

You could get a seat post (not stem) with greater set-back on it.

Depending on the type of bike you have, you could try bending your elbows.

All the best... R
