You could run the cables along the top tube/rack etc, rather than looping/twisting. I tend to use
insulation tape - a single length of it all the way along the wire along the length of the tube
doesn't look too bad. Have a couple of bands of tape to hold the length in place (at both ends, one
or two in the middle, otherwise it has a tendancy to fall off).

The along-the-wire length isn't really necessary with the bands in place, but it does reduce the
snagging possibilities and imo makes it look neater.

Two core does make it a bit easier to do the run neatly.

cheers, clive

Various things I have done to make neat cable runs.

Firstly a straight run looks much neater than twisted round things.

On my tourer the I ran the cable along the top tube taped to the side of the brake cable casing
(this bike has continuous casing from lever to seat stay bridge. With black cable, brake outer
casing and black tape it's very neat.

Running from the rear of the bike frame to the rear of the rack I have used a length of old brake
cable casing with the wire run inside and then the casing zip tied to the rack.

Run the cable underneath the mudguard - drill a hole near the seat stays, pop in a small rubber
grommet, a similar one near the point where the lamp was mounted route cable underneath mudguards,
secured with duct tape.

Not visible at all isn't really an option (there is in-frame routing which helps, but this isn't an
option really unless you are having the frame revamped. reducing it is the best possibility.

Me, I'm pretty much giving up on dynamo powered rear lamps, a decent battery LED or two does the job
with much less faff.

Thanks to both posters, I shall go for a combination approach of running the two strands inside
spare brake housing which I think I can stretch from the rear of the rack to the fork crown without
it looking too bad. I have already adjusted the routing of the cables to put it underneath the
rack's bottom plate and held it in place with two bits of thin plastic drilled so the bolts that
hold the stays onto the rack secure the cables as well.

I want to get away from batteries for good! Nasty expensive leaky things prone to failing at
inopportune moments. Please don't shatter my happy illusions regarding their dynamo brethren
as well...

Much easier to run a single wire through the brakecablehousing, and use the steel spiral for the
connection to earth /Marten

Hmm, I wouldn't trust the connections to the spiral to hold up. Since there's room in the housing
I'll stick to the two cables.
