Nice. If the appearance was bothersome, you could use a
black tube held in place with black zip ties.

Black tube, yes, if I can find some, but I only ever saw
white tube in hardware stores. Black zip ties, no, bad
idea, as they let the tube slide on the sides. I would
rather use some black tape.

Zip ties are also bad in terms of reliability. It seems UV
rays embrittle them and then they just fall off. A while
ago I chased and stopped an MTB rider whose rear brake hose
had come loose because of that and was chafing on the rear
wheel. Luckily I always have a snippet of wire in my tool
kit. Zip ties, too, but those only for temporary fixes.

You can buy UV resistant zip ties. They're loaded with
carbon black that blocks UV. However, not all such zip ties
are equally resistant to UV. Some of the cheap junk has much
less than the recommended 2% carbon black. After having an
antenna installation fall apart in about a year due to
crumbling zip ties, I bought some that are genuine Polyamide
6.6 UV resistant per ASTM D-4066PA411. No problems so far
after about 5 years:

The one that popped was the stock tie from a high-Dollar Specialized
MTB. I can't imagine them being cheap on zip ties. Metal is
generally better.

When I wrote my post above, I considered ending with "Of course,
Joerg would use hose clamps." Now I'm sorry I resisted that
impulse.


No hose clamps, wire :-)

a. Costs less that a cable tie. b. Lasts almost forever. Well, at
least longer than you and I will. c. Much less visible. d. Leaving
the ends longer can provide extra wire for stranded cyclists.


Extra wire for stranded cyclists? I have yet to encounter a stranded
cyclist who was in need of wire. For what?



As I said a fallen off zip tie from a hydraulic hose, for example. I
also have zip ties with me for other purposes but they won't fit through
those lugs.


... A roach clip? "Hey there
mister, say, could you spare some wire? I sure could use some wire,
mister."

You'd be better off carrying some 5M hex screws. You already have
rope. you should carry some extra wheels.

At what point is your bike so trashy that you would mount a U-lock
carrier with wire -- and not even a hose clamp.


My bikes always have a certain trashiness look. Not because of the tools
as they are neatly packed in a belt pack which rides along inside the
right pannier. That also carries my wallet, cell phone, keys et cetera
so during a stop I can whip it out and strap it on. However, the bikes
always have caked mud under the tubes. Cleaning won't make much sense
because a couple rides later it would be back.

The upside of a certain trashiness level is that it makes a bike
unattractive to thieves.
