progress at last!
gears are on - sram 9sp cassette, LX rear mech, dx thumbie on friction seems to get through all the gears ok!
rear brake cable re-noodled with a neater cable routing.
going to test ride in the morning to the station (2 miles) and see how it goes.
still need a narrow wide ring, seatpost, better v's, new rear panier rack, and bars + grips etc.
