Shimano Tourney Centerpull brake
Are there any secrets to those?
I couldn't even find a pic with all the parts. It looks pretty standard centerpull tho, right? -- underground experts united http://user.it.uu.se/~embe8573 |

The main secret is setting up the saddle wire for maximum mechanical advantage. Sheldon Brown has an article on that for centerpulls and cantilevers on his web site and there are other sources. Good brake pads too, the ones with those brakes are likely to be decades old. |

By saddle wire, do you mean the wire-wire or the little arm that could be a wire? BTW here we see the advantage of a terminology poster which John B. ridiculed in another thread Good brake pads too, the ones with those brakes are likely to be decades old. Good point. This one is a Mustang from Trelleborg. It has a "Gel" saddle from Bianchi and the Shimano 5SP Positron shifter with a single chainring front. Perhaps somewhat surprisingly it has a kickstand and a rack. The tires are 32-630 or 27x1-1/4. -- underground experts united http://user.it.uu.se/~embe8573 |

On the chainring it says "Japan Threearrows 46T". -- underground experts united http://user.it.uu.se/~embe8573 |

"Japan Threearrows 46T". Sorry that was from another bike. On the road bike are more "T"s than that! -- underground experts united http://user.it.uu.se/~embe8573 |

I initially trained as a machinist in a shop where actual "Machinists" worked. The Apprentice Master had gone to work as an apprentice himself when he was 14 years old and was nearly 70 years old when I knew him. Not a poster in sight.

OK, so I shouldn't do it, just because some one-dimensional guy you knew didn't do it all his long life? Why are you telling me this, really? -- underground experts united http://user.it.uu.se/~embe8573 |

After all if you don't know the name of things you need help. But why one-dimensional? A guy who was well enough known in the trade that people called him when they had problems? -- Cheers, John B. |

This one is a Mustang from Trelleborg. It has
a "Gel" saddle from Bianchi and the Shimano 5SP Positron shifter with a single chainring. Perhaps somewhat surprisingly it has a kickstand and a rack. The tires are 32-630 or 27x1-1/4. Today I got the shifting to work! The only challenge was that the adjustment screw was behind a plate with a hole in it, only this hole is too small for all my bits drivers to enter, so an ordinary, thin PH2 made it happen. Altho I measured the old chain pin length to around 8mm, maybe 8.1, I put on a KMC Z8RB chain which is 1/2x3/32" with a 7.1mm (9/32") pin length. I suppose it is intended for 8S casettes but it worked fine for the Positron FHEM 5S - at least all sprockets are reachable when the bike is in the stand. -- underground experts united http://user.it.uu.se/~embe8573 |
