It doesn't have to be over - I've build all my bikes just the way I want them.

I just finished up a Raleigh International - moved the drivetrain and cockpit from all the upgrades on my 40-yr Grand Prix. Friction shifting a wide-7 rear on bar-ends, Phil freewheel hub wheelset, Cyclone GT RD, cyclotouriste triple and Shimano 600 EX FD. The bar-end shifters are my old Zeus downtube levers in Rivendell (Diacompe Ene) bar end pods. Zeus road brake levers on moustache bars.

Built up a CX frame as an upright with 2x9 wide compact double - index thumb shifters.

My road bike has 20-naughties Campy drivetrain but with C-Record friction DT Shifters, 8sp Record cassette, Cinelli 64 compact drops, Modolo non-aero brake levers.

None of it makes sense to anybody but me, and that's fine.
