I have a late-80's Cannondale tourer (Sugino AT chainset, bar end
shifters, 126 dropout spacing, 27' wheels and a screw-in hub) It had
''half step and granny" gearing which was a delight when it was newer,
allowing me to trim between the two close top rings to find *exactly*
the right gear.
But that was long ago. The original block and back mech is long gone,
replaced for now by a 14-28 six from a cheap mountain bike. That worked
surprising well with a middle chainring one tooth larger than the
original, but now the chainrings are also so worn that I tend to keep
to one or the other. I want that old feeling back!
Where is a good UK source for new chainrings - currently 48 45 28?
What would be a good modern replacement for the front changer?
As good tyres for 27" are getting harder to find would it be a good
idea to change to 700c?
If that is the case, could I fit a cassette hub with a 12-28 seven?
