i posted this on the classic forum as well
I have a mix of drivetrain parts that i wanted to piece togther for my next build. this is what i have
10 speed chorus rear der
10 speed mirage front der
7/8 speed camy crank
5 speed freewheel mounted to a campy nuovo hub(possibly uprgrade to 6,7,8 speed depending on hub spacing)
campy friction shifters.
I now this is a strange mix of parts but thats what i have.
Your help would be greatly apprciated
so much for physics
It does seem strange but since you are using friction shifters you have nothing to worry about. Your biggest problem will be a chain narrow enough to pass through the cage of the 10sp derailleurs but wide enough that it doesn't get wedged between your chain rings. In addition your limit screws on the rear derailleur will need special attention too.
Hope this helps.
I also believe there's a removable insert in the cage of the 10sp front derailleur to widen it a bit. It's meant for 9-speed compatability.
me have long head tube
Again, it's a strange mix of parts but it will work with friction shifters.
There should be no problem with the chain getting wedged between chainrings. This is largely myth, and useful myth (for corporations) because it makes people think that they need to upgrade their cranks. I've used 9-speed chains with cranksets from old 10-speed bikes (that had 5 freewheel cogs and fat chains). No problem.
As for the chain fitting in the rear derailler's cage, just use a standard 8-speed or lower chain (e.g., SRAM 48 or 58). Works with everything from 8 speed and less, should be narrow enough to work with the rear derailler.
That said, it's sort of a waste that you're using such high-end and current Campy front and rear deraillers. Unless your goal is to use all Campy stuff, I'd put the front and rear deraillers on eBay and use other deraillers. Alternately, you could keep the deraillers and crank and upgrade to 10-speed Campy shifters and new rear hub eventually.
thanks for the info everyone. Like i said this is a strange mix of parts. I didnt plan on getting the chorus derailleur but the company was out of stock on veloce so they sent me a chorus as a replacement. for now i just want to get the bike up and running. sure it would be nice to get a bew wheelset and some campy brifters but i cant afford to.
That would also be my concern, the width of the front derailleur. It seems to me that the narrow 10-speed derailleur could have a chainrub problem with the chain running on an angle.
