Back in the '70s, Campagnolo hubs were like that, perfectly adjusted and slicker than a Teflon banana peel.

Back in the day, I used to do a "Sheldo-Glide" modification to Regina and Atom freewheel cogs. I'd take the freewheels apart and reshape the teeth with a grinding wheel.

You may remember that they had this stoopit groove running along the tops of all of the teeth, which would sometimes cause the chain to zzzzzzzing over the tops of the teeth instead of settling down properly after a shift. I would bevel the inside edge of each tooth, eliminating this groove. I also attacked the front corners of the teeth, making the sprockets look a bit like they had saw teeth, when viewed in profile (the high end was the side the chain pulled against.

These modifications resulted in notably improved shifting.

I also usedta run the brake cables out the bottom of my brake levers, giving a quasi-"aero" effect back before aero levers were available. This was cool looking, and also provided easier access to a handlebar bag, since the cables ran below it, instead of above. I learned this trick from a local cycling legend, Air Force Col. John Vanderpoel.

I also used to like to find various ways to add multiple sprockets to Sturmey-Archer hubs. I had a 12 speed bike in 1960, a 24 speed in '62. My OTB has 63 speeds, but I haven't ridden it for a couple of years. See: http://sheldonbrown.org/otb.html
