switching to drop bars with MTB (deore) derailleurs???
So my lady wants me to switch her Surly Crosscheck that's set up as a touring bike with 32mm tires from a flat bar with deore components (drivetrain and brakes) to some drop bars cause she sees my road and a fixie with drops and she's comfy enough on her bike now for the drops. I can find the bars no problem, my worry is her flat bar shifters/brake levers will not translate to some road drop bars... Does anyone know whether I can get a "flightdeck" like my road Shimano 105 get up and will it still pull the derailleur cables the right amount for her to shift? Any input/ links with info, virtually anything will be greatly appreciated.
Thank You
Thank You

Rear shifting isn't a problem, the front is, unless you go friction shifting, which you will with bar ends.

You use Shimano STI, you will have to change the front derailleur to a road-style one, but no other major changes to the drive-train are needed. You use bar-end shifters and the shifting should still work with the current drive-train, provided that the bar-end shifters either:
1) Match the amount of cogs on the cassette (i.e. Shimano Ultegra bar-ends are 8-speed, and will work with 8-speed rear cassettes).
OR
2) Has a friction-shifting option for the rear cassette, in which case, it could be used with just about any cassette. The front derailleur shifter for bar-ends is usually friction-only, which means that it could be used for just about any derailleur.

OR You can use bar end shifters from Rivendell and use whatever you want.

I'd try the new set up with the current derailleur and see if it works. Sometimes it does, sometimes it doesn't. If it doesn't, a new FD is a pretty cheap and simple fix.
Don't give 100% credence to Shimano's compatibility charts. I am currently using a "flat bar" specific FD with a set of R500 8 speed brifters.

Replacing the front derailleur might not be a simple fix. Road front derailleurs are all bottom pull design. Most mountain style bikes use top pull derailleurs and the cable stops and guides will be in the wrong places.

Check the current Shimano MTB lineup for front deraileurs. Most are dual pull and can be used with top or bottom pull cable routing.
