Yes- the distance between the inner faces of the rear dropouts. 110 mm is or was standard for track bikes, 120 for 5 speed and some 6 speed, etc. up to 130 mm for 8/9/10/11 speed (road standards, 135 mm MTB standards). As the cassette gets wider, the wheel dish becomes more severe and the rear wheel gets weaker.

With a 7 speed freewheel and the larger OLN, the wheel has very little dish and is very strong and stable. I should probably go to a MTB or tandem rear hub (135 mm to 145 mm, respectively) on my road bikes and reduce my wheel problems considerably.

So at least 27 years touring bikes have used 135mm. Used Deore DX hubs. Mountain bike hubs. Dropped perfectly into my newer Redline Conquest Tour frame. |

Live and learn -- what is odd is that Trek spec'd the Portland commuter with odd-ball 130mm discs during the same time period. One wonders why the product designers were not talking to each other. Speaking of discs, if I got a new touring bike, I'd certainly get one with discs, although discs limit your wheel replacement options if your wheels explode in outer Mongolia -- but not outer Magnolia. http://www.mapmyride.com/us/seattle-...de-route-58399 -- Jay Beattie. |

I recall that during the touring bike heyday of the 1980's 700 x 35 was the default choice for bikes like the Specialized Expedition, not sure about the competing Miyata 1000, it may have come with 700 x 32. Those were the two best touring bicycles back then. There was a a slew of others from various companies like Nishiki and Shogun. |

I have a book from 1994 [1], with previous editions -78, -83 and -86, and in the randonneur chapter (pages 289-413) the author mentions two bikes, one is the Miyata 1000 (photo with a back rack and front side racks, fenders, and three water bottles), the other is the "Follis Lyon" (photo with rear/front side racks, only no traditional rack, fenders, and only one bottle holder).

I've just finished a book on randonneuring,
namely @book{long-distance-cyclists-handbook, author = {Simon Doughty}, ISBN = {0 7136 5819 3}, publisher = {A \& C Black}, title = {The Long Distance Cyclists' handbook}, year = 2001 } The book is very meticulous, typically British with lots of illustrations, tables, etc. The only surprising thing is that it is also about cycling in general - those sections are great as well tho so I'm not complaining. Perhaps the author had a hard time selling the book with the title "My Book About Cycling"? -- underground experts united http://user.it.uu.se/~embe8573 |

You are talking about touring. Not randonneuring. The early 1980s were a very few years after 1976. 1976 was when Adventure Cycling (they were called something else at first) organized the first cross country USA bike ride. It was not the first time anyone had ever ridden across the USA. But it was the first nationally publicized cross country ride with a "big" organization sponsoring, organizing, it. They organized groups of riders and had ride leaders for each group. So bike companies were merely trying to capitalize on this new market for touring bikes. Riding a touring bike across the country was a new thing. And you needed a new bike to do this. A touring bike. Thus companies made the bikes people wanted to buy. Its called capitalism. Companies sell what people want to buy. |

Why not just pick one or the other? Unless they figured only the professional tourers would buy the 700C because they knew about bikes and what the rest of the world used for tires. 700C in Europe. And the 27" was marketed to the beginner who would only tour around his house in the USA. 27" tires for USA. |
