I have an old Falcon Team Race (http://www.bikevintage.com/falconbik...n-reynolds.jpg not mine). I have a Rival rear shifter and a matching SRAM single speed left brake lever sitting in a box collecting dust. I was thinking about putting them on the bike and using the downtube lever for front shifting. I have a set of Askiums that are not being used that could be used for the wheel/cassette. If I'm just a rear derailleur away from turning this into a 10 speed rig, I'd be very keen on doing that.
I worry that there might be issues with the width of a 10 speed chain on a crank used on an old six speed drive train. I've checked - the BCD is smaller than 130 so I can't use any of my other chainrings. Anyone have any experience with this sort of stuff?
Also, if anyone has a good resource, I'd love to know more about the bike - I don't know anything about Falcon.
