Specialized transition TT frame set

Specialized transition frame with 10 speed shifter and rival rear derailer and crank set with specialized sitero saddle in a size 56, only thing that doesn’t work is the cable going to the front derailer and I don’t know if it’s worth trying to route a new one so probably be better off using as a single ring in the front and just tightening the front derailer on the front ring , local pick up only thanks
