Cable sleeves?

hello all, my first dumb question to be followed by others I
'm sure. I just bought a new used tandem and in the process of cleaning and greasing everything. the cables from front to back are just bare(no sleeves) and I was wondering if I should cover these hope that makes sense. if it matters its a 95 18 speed tandem mountain bike that I am converting to a street bike. also any other ideas on this conversion is greatly appreciated thanks.

You need housing to support the cable for flexible and bent runs, but not along the frame where it runs in a straight line between braze-on fulcrums (aka cable stops), or around fixed pivot points line the bottom bracket.

So there's no need to cover those bare wires. But the next time you replace the cables you might want to cover them so you won't scratch the frame if. for example, you grab it by a frame tube to carry it.

If you do chose to cover the wire along the frame, cut the cover a bit shorter than the span, so it can move back and forth with the wire and not increase friction by causing the wire to slide within the cover.

Also, you might find the liner tube of plastic, to span between braze-on stops.

Or, just buy stainless steel cables and the bare cable won't show rust.

Hello:
Good information posted above. I might suggest that you jump to the tandem forum if you have tandem specific questions. TandemGeek is an incredible mechanical resource for tandems.
Question for you...how are your derailleur cables routed under the captains and stokers bottom brackets? Are they externally routed through a metal tube, internally routed, or just sit in a narrow groove on the underside of the BB's? You have options to reduce friction and protect from dirt with each option. Also, how is your rear brake cable routed? As posted above, most of your cables are exposed. You can reduce cable slap against the frame by installing several small rubber donuts on the long runs of the cables. Your LBS should have them. I use two in front and back on my rear brake cable and two underneath the boom tube.

Thanks for the quick responds and info. I have two cables open to the elements that run under the cap an stokers BB's one for the frt. DER. and the rear brake that are held in place with a couple cheap plastic grooved brackets. they just did not seem that secure so I thought it would be better to have them housed and secured with clamps but did not know if that was overkill or not. I have been working in aviation for 35 years so I kind of overkill and am anal about most everything I work on but I think I can be cured with cold therapy.
