Bikes: I've lost count.
Dahon: 1
c1910 Racing bike: 1 (fixed)
c1930 Racing bike: 2 (flip flop)
Humber Sports: 1 (S-A AG three speed, soon to be S-A FG four speed internal)
Robin Hood Sports: 1 (S-A AW three speed)
Healing Cruiser: 1 (Shimano three speed internal)
Raleigh 20: 2 (double fixed)
Burco: 5
Morrison MTB: 5 plus a triple up front.
Currently only the Morrison is indexed. Just sold a recumbent with a triple and 9 on the back. Will shortly purchase a different bent with a triple and 9 speed.

And now for something completely different: Lon Haldemans PBP bike. A three speed rear cluster with no derailleur. A three-speed singlespeed?

'61 Paramount: 2+5 (54/51 up front with a 14-16-18-20-24 freewheel) - My favorite
'81 Trek 610 2+5 (52/42 w/14-18) - haven't tried it, not even sure if the FW is good or worn
'82 Trek 728 3+7 (50/48/28 w/14-22)...I think
'84 Raleigh Competition 2+7 (52/42 w/13-22) Again, IIRC
'84 Raleigh Alyeska 3+6 (48/40/30 w/14-24)
'86 Raleigh Grand Prix: 2+6 (52/42 w/13-18)
'87 Basso: 2+6 (53/42 w/13-18)
'9? Guerciotti: 2+8 (52/42 w/13-20) - Shimano 600 STI
P.S.: All except the Trek 728, Competition, Alyeska and Guerciotti are running Campagnolo (pre-slant parallelogram) gear trains. Basso and Grand Prix are running Shimano 600 UG cogs, all others running non-ramped cogs, except for Sachs rear freewheel on 728.
Take care,
-Kurt

Say Road Fan, how's that mega range working out for you? I'm thinking of putting the 14-34 one on my '87 Paramount, which runs a 53-19 C-Record crank in front. Sheldon Brown recommends a Shimano LX RD to go with the Mega range setup. I'd like to know your experiences. I'm looking to use the Paramount for riding in the Shenandoah Mountains and the foothills.
If you're going to index, you might need to be concerned about Sheldon's suggestion. If you're not, you just need a derailleur that can move the chain onto such a large cog (range), and that can wrap up 34-14+53-39 = 34 teeth (capacity). I assume if he calls for it the Shimano LX is capable. What I've used is a Huret Duopar, which easily has the capability.
I use a 9-speed chain, but 8-speeds have worked well for me, too. I think a 5-speed chain would be too wide.
I feel these freewheels and cogsets benefit from Shimano's excellent tooth designs, which are very efficient at picking up and releasing the chain during shifts. I think that even if you put on an ancient Campagnolo Gran Tour or a long-cage Huret Allvit (reaching back 45 years here!) you'd get good shifting because the sprocket teeth always grab the chain instantly.
When this quick chain/cog action is combined with a Duopar or Ecopar, that always maintains optimal free chain length due to its vertical parallelogram design, you get very quick shifting with no perceptible overshift or undershift: the shift always happens with only one lever pull, no fine jockeying to eliminate noise unless you pulled too far or not enough.
Who needs indexing? This is precise, silent, and consistent, and I can still shift across the entire cluster at once if I want to.

Thanks Road Fan. I'm not going for indexing. I just don't see a need with a 7-speed. What I find with indexing is, if I get tired on a ride, I fiddle too much with the shifters and cause all kinds of goofiness.!
