Back in the days when men were iron and bikes were steel.... I just don't know.
There are a lot of Stronglight guru's here.
I can only recommend the muggleBay site, and if I remember, a lot of Stronglight rings on Bikeinn.

I remember a coupla hills in Newport, a few on the way to Barrington via the New Hope Bridge,
and maybe one or two near URI....but RI is not flat, that's for sure.

BCD is your gotta-go-to number.
