Shimano Sora 3500 (3x9) and Alivio front derailleur Please help rebuild my bike :)
I have Scott Sub 30 2011 http://www.evanscycles.com/products/scott/sub-30-2011-hybrid-bike-ec025449 and right now I would like to change shifters to Shimano Sora 3500 (3x9).

I'm wondering - these shifters will work with front derailleur and crank?

Crank: Alivio FC-M430-8

Chainrings: 48 × 36 × 26 T

And front derailleur: Shimano Alivio FD-M430

Thank you in advance for your help!
I'd say that based on the fact that you have a standard KMC-9 chain, and that you're keeping it 9-sp all round, you should be all-right.  

As noted in the comments, you'll need to change your bars too else you'll not be able to shift and brake correctly, but you said you are.  

Only thing I am not too sure of, is the FD. If I were you, I'd just try to use the Alivio you have, and if you have any issues, just replace it with a Sora FD-3503.  They are cheap enough.
