Crossing shift cables?

I tried the search, but i'm 67 and would like to ride my bike this season . . .

replacing my cables. bar end shifters (like).

thought there might be less kink if I crossed cables under the downtube, but don't know of other effects to consider. any help appreciated; thanks.

People do it. To prevent aggressive bends, as you mentioned, and in my case, to minimize cable rub on my head tube.

The cables barely touch where they cross and the friction and wear are negligible, certainly less than making an overly-tight bend inside a housing.
Slightly off topic, but brake noodles, intended for V-brakes, come in different angles and can be used to help turn corners cleanly in tight situations.

Yep, it's a pretty common practice. I've done it to all of my bikes for at least 25 years. It makes the cable routing more like a lower-case 'r' than a '?' especially on MTB / flat-bar bikes, where the shifter is a lot closer to the stem.

Another tip, if the cables are really close, or even almost touching the frame tube, run the FR cable closest to the frame. It moves less often, and can provide an extra support for the RD cable, to keep it of the paint, since it moves a lot more frequently. Also on large-section aluminum or carbon downtubes, it'll make less noise that way.

A short section of casing liner "tubing" at the cable crossing will help reduce the paint rub. Run both cables through it. Andy

thanks guys. got new tubes & tires and chain on today. tomorrow new brake shoes & straddle cables. then i'll tackle the cables. And- I actually polished the frame & fenders while everything was off. saddle waxed top & bottom w/ proof-hide. newbaum's yellow tape, twine, & shellac will be the last thing, after test ride & adjustments.

cripes; I may actually have to ride it pretty soon!

thanks again

ok; in from the shop. made some good progress.

now . . . on a scale of 1 - 10, how bad is it to connect two sheathed cables together (loosely) to preserve symmetry? it would be just above my stem, and a zip tie would do it, but i'd like something a bit more esthetic if possible.

breaking all Velomati rules?

I do it. Sometimes it makes the cables rattle less, and also helps eliminate flex in the cables.

It is doubtful that anyone else would notice. If you want the pro solution, try these:
