The next steps up from the Gran Sport would have put you on a Professional or Competition... and it is a very light frame and fork which is indeed, very responsive.
My Gran Sports has lived life as both a fixed gear and geared road bike and with the decals being in such shabby shape I opted to get creative when I turned it back into a fixed gear bike.
In either form it has been an excellent ride in every way.
I found mine at a second hand store for $10.00...it had it's original stem, bars, and Carlton levers (also lovely) but the other parts were cheap replacements.
How she looked a year or so ago... I had her built up with a Shimano 600 Arabesque group.
