I have a Raliegh falcon touring frame, which I've been upgrading gradually as it's in good nick, putting modern componants on it.
I've got to the point where the next thing I need to do is upgrade from down tube shifters, ideally to combined brake/shifters. I've got a triple chainring on the front (sora) and 6 speed on the back, with 27 x 1 1/4inch wheels. The rear shifter is indexed, whilst the front is not. I'm aware I'll probably have to install a new rear derallier at the least.
So I have two questions. Can I get any more gears on the back? Do they make 7speed rear cassettes for older bikes?
And secondly, looking at sheldon browns website, the Campagnolo "Ergo" set would let me keep the front unindexed -am I correct? And is the rear shifter modfiable to a 6speed, if I can't upgrade the rear cassette?
