The Coda Sport is more like a "touring" bike, again, jmho. I use the Coda as my utility/touring bike and my allegro as my "club riding bike", I call it my, "roadster". The Allegro has the "S-bend chain and seat stays" and with a "switch" to 700Cx25 road tires, it's faster than the Coda but not as "over all comfortable" as the Coda.

Also the 19" inch Allegro top tube is "1 inch" shorter than the 21 inch Coda so if you've got longer arms the Coda should be a bit more comfortable, if you've got shorter arms the Allegro would be a better fit. The Allegro has a "up sloping" top tube the Coda has the slightly down sloping, (compact) top tube. That's WHY the "standover" height is so close between the 19 inch Allegro and the 21 inch. Coda. YMMV, whatever you get, ENJOY! BTW I also have that Serfas RX SPORT seat and like it. FYI.
