Very nice. I was out for on my '76 yesterday on our Schuylkill River Trail. The Pro just does everything well and the British chrome is as nice today as it was 40 years ago. Mine is sorta franken because it has changes that, I believe, would have been done BITD by an enthusiast: different wheels and crankset. I was the one who swapped in the Suntour ultra6 and the 9 sped chain.
As I did, you may also find that it's a lovely bicycle.
