I'm converting my 1999 Litespeed MTB into a monster cross and wanting to do it with minimal cost. I've got Sora 3x9 shifters and XTR FD & RD. I think the RD is fine with the Sora shifters but my LBS recommended changing out the FD to a road one. Will an Ultegra FD-6703 work? The crank on there now is 44-32-22. If this doesn't work, any suggestions?

Is the drivetrain on the 1999 Lightspeed original?

The issue with the FD is that a 44 tooth ring has a greater curviature that a 50 or 52 road ring. The curviature of the FD must match or shifting will suffer.
