>>2028306Maybe someone can correct me but I think control diameter on drops is basically universally standardized. At least, I've always swapped controls between "classic" and modern bars and not had issues.
By all means use bar ends. They lack the instant "snap" of downtube shifters due to the extra bit of cabling, but I imagine nice modern housings and hyperglide would clean that up nicely. That bike had a ratty drivetrain. You can kind of slide your hands down the outside of the hooks to shift from whatever riding position, so you really don't have to take your hands off the bar when it gets bumpy, which is obsiously really nice. You might think they would be fragile in such an exposed spot, but I abused the shit out of that thing and those shifters are the one thing I held onto when I got rid of the bike...
