Current ride is a 60cm Crosscheck with a 60cm seat tube and 60cm top tube. The fork has 400mm axle to crown, 44mm rake. Seat tube angle and head tube angle are both 72. The chain stay length is 16.7" (claimed) and bottom bracket drop is 2.6".

The bike I'm considering is 58cm seat tube, 59cm top tube. The fork has a 45mm rake with 400mm axle to crown. Angles are 73, 73. The chain stay length is 17.1" and the bottom bracket drop is 2.75".

Both bikes are cross/commuter/do everything purposed bikes.

I'm just trying to find out what changes in handling or stem lengths, seat post (layback or not) I should expect.

Thanks in advance..I know that's a lot of stuff.
