Andre Jute Visit Andre's books at http://www.audio-talk.co.uk/fiultra/THE%20WRITER'S%20HOUSE.html Andre, Santos has a bike (in development) with a belt drive and they are very pleased with the performance. See this report of a ATB race in the hills in the south of the Netherlands famous for the very sticky mud. I can confirm that. The drive (with a Rohloff) worked perfectly. I once took part in an off road ATB race over there and a derailleur drive doesn't work in those conditions. Every 10 km you have to scrape the mud from between the sprockets because the chain skipped. I went through a complete set of brake pads within 25 km. In the report the said after the race a rinse with a hose and the bike was ready to go for the next race. The advantage compared to a Rohloff hub with a chain is that you don't have to clean and lube every ride I think.

http://www.santosbikes.com/?ct=bikes...ive=265&bik e type=,santos,santos I used Babelfish translation to read it in English. The term "oar" keeps cropping up. I doubt it's a cute figure-of-speech because it's so frequently used. What, in this context, is "oar"? Dave |

(scroll to the bottom photo) Hmm... major frame modification required. Chain stays must be extra strong? Maybe this is the advent of bolt-together frames (at least the rear triangle)? |

I can't find it in the Dutch text. Can you copy paste a Dutch sentence with that word in it? Lou |

Yes you have to have a special frame for that. Extra strong? I doubt. That part is in compression. Look at some modern frames. These tubes are getting very skinny in diameter; for comfort reasons they say. Lou |

We sold quite a few Bridgestone toothed-belt drive the last time the fashion came around. Almost as good as a chain, but with a bonus "my bike is special" factor. chain, belt, whatever. Both systems have advantages and disadvantages but I don't find belts compelling. If you do, then by all means try one. -- Andrew Muzi www.yellowjersey.org/ Open every day since 1 April, 1971 |

Lou Don't worry about the Dutch; I speak better Dutch than those two guys who wrote the Santos literature. I'm very happy to have this Santos reference. I especially like the bit where he says he guarantees the Rohloff hub a bigger distance every year, when he has himself ridden further without trouble. There's a guy you can buy a bike from with confidence! Get back to you about the belt drive when I've read the external reference http://www.beltdrivebicycles.com/ Andre Jute Global Warming is like Scientology, only with less science |

Advantages, disadvantages, why you fail to find belts compelling. Rereading Lou's posts, I just discovered that a special frame is required... That makes it expensive to buy one "just to try"!

I understand that the latest iteration of carbon fiber reinforced belts from Gates does not require as much static tension as previous versions. This reduces drag and wear on both hub and bottom bracket. Seems like belt drive would be a good companion for a coaster brake, airless tires, one-piece crank, etc. A bike equipped this way could provide an unmatched degree of readiness. Chalo |
