Changing Campy index downtube shifters to 'only' do friction shifting How do you change Campy down tube C-Record indexed shifters to be friction shifters? I don't like index shifters as they limit your options with the cassette you can use.

Mine are Campagnolo Veloce.
I'm not familiar with those shifters but perhaps this will be of assistance: Campy Syncro 2 shifters

The left/front shifter is a standard friction shifter.
To convert (the right one) to pure friction, you can actually just remove the springs and optionally the boss collar -- the springs are all that is required to (re)move.
