being more of a tourer type, with bikes with racks and whatnot, on frame areas where contact can occur with stuff, I've often put some electric tape or hockey tape just so the paint doesnt get rubbed off and or abrasions. Electric tape stays on reasonably well and you usually can put it on discreetly just on the abrasion point and its easy to take off too.

but thats good that you have changed the setup, the cables would definitely be rubbing against the frame all the time.
