Hi All,

Hopefully this is the right place to post...

I was recently given some Sora 8's. I was also given a spare 80's Motobecane Jubilee Sport (I just bought a fully functional one. A friend heard about it, and gave me theirs as a parts bike). The frame is in pretty bad shape, but the rest of it, including Suntor ARX front/rear derailleurs, works nicely.

The Sora's have no cabling with them - I've looked around on ebay but can't figure out what cable these would need, and if there are any good-value alternatives. Can anyone point me in the right direction?

The other piece is that I want to learn more about bikes, so I'd like to try switching out the front DT shifter for one of the Sora's as a way to teach myself. I realize that an STI upgrade is not cost-effective, and I don't intend to do the full thing - it's a learning exercise.

Sheldon Brown appears to indicate (http://sheldonbrown.com/upgrade-gears.html - look under the "Front Derailer Indexing") that there's a possibility of not needing to change a FD on a double when doing this sort of conversion. As I read it, even thought STI's are indexed in the front, there are only two positions anyway on a double, so the point is somewhat moot. What's the likelyhood that, just for the front shifter, it would be possible for the Suntour FD to work? I know there's more to it than that, but for now assume that I have the cable stops and everything else sorted out.

If this will not work, any thoughts on a compatible FD that wouldn't require a change of the crank or front rings? The larger chainring is a 52. Nervar cranks, and probably swiss BB (hence the desire to avoid changing these)

Thanks!
