When I first got my Zesty 514 (2012 carbon version), I pulled out the front mech cable and converted it straight to 1 x10.
Now I want to convert it back to gears at the front, but I'm struggling to figure out the correct cable routing. It seems there's a hole through the brace between the chainstays that takes the front mech cable up from below the bb shell to a guide cam on the mech and over to the clamp bolt. However, it looks to me that the cable is going to rub a groove where it comes out of the hole in the chainstay brace. Do I need some kind of sheath or cable sleeve?
Could anyone take a photo of the cabling at the front end around the bottom bracket of a Zesty? Preferably a carbon one - I don't know if the alloy one is similar or not?
