Dynamo Lights viz Battery Lights in snow qand slush?
How do these new hub dynamos perform in snow and slush? I'm thinking of that brown mollasses like crap that occurs when roads are salted but not plowed and said brown crap builds up quickly on anything sticking out of a bicycle. Does it build up on the hub dynamo too? Does it affect the performance of the dynamo/light? Does it corrode the dynamo or its inner parts? Does it put undue stress on the wire running from the dynamo to the light?
Cheers |

And yes they get covered in salty muck just like your feet and everything else. Salt water will find its way inside just about anything eventually, for example this 'sealed' Nexus: http://www.yellowjersey.org/photosfr...t/nx7brokn.jpg The Sanyo of the 1980s were terrible for that, not as resistant as a Sturmey GH6. Most modern units, even cheaper models, are better now. Wiring isn't any different, some setups are easily snagged but good planning avoids that. Contacts can be coated with dielectric grease usually $1 at any auto parts store. -- Andrew Muzi www.yellowjersey.org/ Open every day since 1 April, 1971 |

As I understand it, taking the bike from the relatively warm basement to the outside cold causes the internal air to contract and suck in the nasty stuff. I anoint the S-A units with oil from time to time, hoping that's enough to magically ward off evil. But the Shimano has no provision for that magic. (SON uses different, more effective magic, it seems.) -- - Frank Krygowski |

That's why my SON has some pressure exchange holes to prevent the nasty stuff from feing sucked into the bearings (my first one did not and died of winter corrosion after ca. 8 years). |

yes, this was the next ignorant question.
Frank, look thru di-electric silicone lubricant grease...not oil...oil is 19C are you ready for a Morse Berto generator ? |

It is a clean, translucent oil with superior anti-wear and extreme pressure properties, suitable for lubricating spur, helical, herringbone, rack and pinion, straight and spiral bevel, and worm gears. Excellent oxidation resistance, rust and corrosion protection and the ability to readily separate from water, make it ideally suited for chain drives, worm gears, and gear boxes. HHHHHHHHHHHHHHHHHHHHH Syncopen® Synthetic Penetrant Bulk (Metal Protectant) Super Lube® Synthetic Penetrant is a fast-acting, penetrating solvent and synthetic oil that cuts through rust or corrosion. Syncopen® penetrates hard to reach areas to allow easy removal of rusted and corroded screws, nuts or bolts.
