freehub and downtube shifters
I have a rear wheel that has a Campag screw on hub. The BB on the frame is
Shimano. I would like to utilise it as a commute/trainer bike and so would like to just have a single 42T chainring and use a wide range of sprockets at the back. Could I use a downtube friction shifter so that there would be no indexing problems with the Campag/Shimano setup? Given this, what rear mech would you recommend for, say, a 12-32 setup? MTB type? Many thanks in advance! |

This may not be as reliable as you might expect. Running a rear derailer with no front derailer, it is not uncommon to have problems with the chain falling off the chainring. Could I use a downtube friction shifter so that there would be no indexing problems with the Campag/Shimano setup? Friction shifters are generally compatible with anything, if you can stand downtube shifters, there's no problem. Given this, what rear mech would you recommend for, say, a 12-32 setup? MTB type? You want a wide range rear mech. Current marketing-speak does call wide range derailers "MTB" type, though they might just as well be called "touring" deraiers. I'd suggest a Shimano model with an "SGS" cage. Those will generally handle up to a 34 tooth sprocket.

The indexing doesn't care that the bottom bracket is Shimano, only the rear derailleur. Be that as it may, with friction levers you can use any mix of equipment you want. Also, with a freewheel (your "screw on hub"), you don't need to use the same brand derailleur as the hub. Some freewheels exist for Campy 8-s[eed, but most will be set up for Shimano. Given this, what rear mech would you recommend for, say, a 12-32 setup? MTB type? For a 12/32 probably a mountain bike real derailleur would be a good idea. -- David L.
