A modern nylon plate under the BB works very well. I added one in 1985, no trouble since. How does that work? Like two small tunnels? They don't get jammed with dirt from being so low, under the bike? And how do you attach the plate? As for rust, obviously that isn't a problem with the small Torpedo pulley wheels which are of some white plastic (?) - however parts of the flanges to make the chute are sometimes missing (broke). Perhaps this happens all the more here because of the winters, but plastic parts are almost always defect in some way. Only sticky tape on bikes are much worse still... An example (of plastic) speaking of Torpedo is the three speed controller vs. actually both versions of the five speed controller. The three speed one is much less plastic and is almost always just open, clean, oil up and it works instantly. On the other controllers, which are much more plastic (especially the one with pozidriv screws) today I disassembled two, to get one, as on one, there was a crack in the back case part, and on the other, a crack in the arm! But apart from being in plastic, I actually like the "pozidriv screws" controller - very easy and fast to operate... -- underground experts united .... http://user.it.uu.se/~embe8573 Emacs Gnus Blogomatic ......... http://user.it.uu.se/~embe8573/blogomatic - so far: 52 Blogomatic articles - |

They don't get jammed with dirt from being so low, under the bike? And how do you attach the plate? See https://en.wikipedia.org/wiki/Cable_guide The metal guides above the bottom bracket are the older design and the plastic guides on the bottom of the BB are the more recent. As for rust, obviously that isn't a problem with the small Torpedo pulley wheels which are of some white plastic (?) - however parts of the flanges to make the chute are sometimes missing (broke). I don't live in the land of the midnight sun, but using the better quality brake or shift cables and a bit of grease on the guide I've had no rust problems.

Aha, those! - but I have not seen those being manually/mechanically attached to the frame, but that's something I'd like to do, for sure! -- underground experts united .... http://user.it.uu.se/~embe8573 Emacs Gnus Blogomatic ......... http://user.it.uu.se/~embe8573/blogomatic - so far: 52 Blogomatic articles - |

The metal guides are usually brazed on although there a time when they too were clamped on. See http://tinyurl.com/jz3tgkq -- cheers, John B. |

AFAICR: the ones fitted during manufacture have a nut welded on the inside of the BB tube section - presumably you could retro-fit with a self tapping screw. |

AFAICR: the ones fitted during manufacture have a nut welded on the inside of the BB tube section - presumably you could retro-fit with a self tapping screw. I've never seen that. Possible I suppose. The original Vitus design popped into a large BB hole with a molded plastic peg on the frame side. There were others after with a locating peg (the gear wire(s) hold it against the frame). Trek's first design had two 3mm screws threaded into the BB shell, like a mini belt-with-suspenders. Modern ones thread a 5mm screw into the BB shell, no nut. -- Andrew Muzi www.yellowjersey.org/ Open every day since 1 April, 1971 |
