c section bowden cable outer
Hi All, I have a bike that has 3 lengths of exposed Bowden cable. Id like to sheath these, but would like to avoid having to disconnect and reconnect the inners. Can anyone think of a suitable (preferably black) C section thingy in plastic / rubber / Ali that I could slip over them? -- Chris |

Hmm, I think that would look utterly pants and probably create more problems than it solves. Not quite sure what the OP has against exposed inners or just using standard cable outers.

But unless that was abrading the frame somehow, isn't the only real 'weak spot' any open cable guide or upward facing, short outer-link that might collect crud (down the hole between inner and outer, often nylon lined these days)? While the split conduit that I suggested is not completely waterproof (unless it is glued shut) it could be expanded and taped over the posts supporting the ends of the existing "outers" to minimise water ingress at these points. No, all the other options could be perfectly valid, *depending* on what the OP was trying to achieve ... and a 'slip on' solution was closer to the desired solution of something that required the loosening and re-threading of the inner (and we know how much of a pita that can be if the end is at all frayed). ;-( Cheers, T i m |

If just a cable it would need pulleys etc to go round bends. On bikes (typically for derailleur gears), you sometimes have stretches of bowden cable for the curved bits and then stretches of "inner" that run between pillars on the frame, these support the ends of the bowden cable at either end so that the inner remains in tension. The inners typically have a nipple only at one end for the operating lever, so they can be fed through everything. They sometimes have a pulley wheel for changes of direction. The free end is fixed by a screw clamp in the derailleur mechanism. My reading is that the OP wants to "sleeve" the exposed cable for some unspecified reason. |
