Cable routing on mountain bike.
Rebuilding a pretty much stripped frame, it looks fairly simple, but so far
I've only got as far as buying the cable. Some guidance would be handy before I start cutting.......... An email to the manufacturer went unanswered and Sheldon Brown doesn't get that specific on cable routing. Google wasn't much help either. Its the cable layout that runs in a plastic runner under the bottom bracket. The bike I'm using has all its cable runs along the top tube. Thanks for any help. |

If the cable stops are all on the top of the top-tube than, usually, you just use the existing cable and the bare cable runs between the cable stops. http://tinyurl.com/hhxy2yl If it is a road bike than usually the rear brake cable runs either above or below the top-tube. If no cable stops than the cable housing is probably attached to the top-tube with small clips. http://tinyurl.com/gwb9r4o The two shift cables run below the down-tube. With either cable stops near the front of the down-tube or if designed for down tube shifters than no cable stops at al. http://tinyurl.com/znpav2e -- cheers, John B. |

Doahn leave cables bare on top tube
Install new BB cable guide Generous loop into deray with quality housing Search eg diamondback: https://www.google.com/search?site=&...k1.ZUpcw5D9CyA |

I guess your reading comprehension hasn't improved - I stated that it has a plastic cable guide under the bottom bracket. Also I stated that the bike I'm using has cables along the top tube - most people would understand that I can't just copy that on the frame I'm building. |

Various pictures of cable fittings, but what I really need is guidance on routing of each whole cable. It probably isn't all that difficult to figure out - but a diagram would inspire more confidence before I start cutting cable outer. |

Now it seems to have changed to "under the bottom bracket" which is a bit different. -- cheers, John B. |

Cable routing on mountain bike.
uh thinking is the frame is older n a new guide .....costing peanuts.....is from a generation better plastic .....
as for the top tube ? no reason producing developmental situations when the wires are just as good where the engineer placed them. my reading ability is good. speaking with hardheads isnot in odor |

Methinks the bike he wants to put the cables on has an under the bottom bracket cable guide and thus needs cable run there. Why he mentioned the top cable guide bike is beyond me as it certainly confused the issue. He needs to run the cable housing to the cable stops (most likely) on the down tube then run a short length of cable housing from the chainstay stop to the derailler. He needs to offer up the cable housing to each location. I'd do it by stciking one end of the housing into a downtube cable stop and then whilst keeping a nice gentle curve in the housing take the housing to either the brake lever or shif lever on the handlebar. Make sure the handle ba/wheel assemble can go side to side without pulling the cable housing out of the stop. When that length is determined then cut the housing and use that piece to measure another length of housing for the opposite side. Repeat as need for other cables. The rear derailer cable housing usually has about a 3 inches radius from the derailler stop to the derailler. make surethe housing is long enough to allow the derailler to pivot throughout its full travel.

Methinks the bike he wants to put the cables on has an under the bottom bracket cable guide and thus needs cable run there. Why he mentioned the top cable guide bike is beyond me as it certainly confused the issue. Sure. I've got a bile like that. I think that it used to be common with hard tailed mountain bikes. See https://www.flickr.com/photos/lovely...le/7854734170/ but if it has the cable stops on the top tube then it has the rest of the cable stops to route the cables. But most of them used, I believe, top pull front derailers, or the more modern "either way" derailers, so if he has the "wrong" type front derailer something has to change. He needs to run the cable housing to the cable stops (most likely) on the down tube then run a short length of cable housing from the chainstay stop to the derailler. He needs to offer up the cable housing to each location. I'd do it by stciking one end of the housing into a downtube cable stop and then whilst keeping a nice gentle curve in the housing take the housing to either the brake lever or shif lever on the handlebar.

The rear derailer cable housing usually has about a 3 inches radius from the derailler stop to the derailler. make surethe housing is long enough to allow the derailler to pivot throughout its full travel. That is the way that most people do it, anyway :-) -- cheers, John B. |
