downtube shifter on aluminum frame
I want to install a downtube shifter on my Cannondale aluminum bike. The shifters I see advertised all come with a short tubular piece that is "carved out" to fit on a standard steel frame. Judging from the shape of the fitting on my aluminum frame, I need a part that is not carved out at all. Do such parts exist?

Or, you could try something like this.

I have downtube on my 1977 Peugeot and 9 speed Tiagra shifters on my Gunnar.
And I gotta admit I love shifting on my handlebars. If it made fiscal sense, I'd lose the downtube shifters.
Ok, downtube shifters are nearly indestructable and cheap, but aren't they a pain in usage?

1. It's a classic frame (Colnago Classic) and I'd like to maintain its vintage...
2. Makes you want to train your legs to spin a harder gear and get faster that way (yes, it's because it's a pain to shift so you'd rather get to an optimum cadence on the current gear )
3. Friction mode doesn't care how many sprockets you have. 10s anyone?
Anybody else got their reasons?

I had the same problem with my dale. I ended up grinding down the curved parts to be flat. If you do this make sure you leave the square indentaion in the part. I know it's a hokey fix, but it did work fine and cost nothing.

My first road bike (a 68 Schwinn) had the then new innovation of stem mounted shifters, which permitted shifting with less of a movement from the handlebars. That system, though I like it much better than downtube shifters, still falls short of the modern technology or even the older trigger shifters for reason of removing the handlebars a milder distance from the handlebars to shift.
