For a Boston Bicycle shop Harris Cyclery going out of business go to Craigslist NY ''Vintage lightweight bike parts, LONG LIST '' for a Nice list of Campagnolo parts NIB Plus a lot more beyond Campagnolo. Not inexpensive however Charles nighbor Walnut Creek, CA PS took my new 80's Cilo all Dura ace for a slow spin has that is what it was set up for with fat 28c tires. Started up long gradual Franklin Canyon Road and heard some riders approaching from behind. kicked it up a notch or two or three and that was the end of a slow easy ride. Lovely ride.
