re:Lance movie
In category Racing
Written by Jenkins

Some day Hollywood will make a movie about Lances's 7 Tour de France victories. We all know, as cyclists, that it will bomb at the box office.
Let's face it, if you arn't a cyclist you don't have a clue about what's going on in the TDF. So I don't expect the movie to be a high budget one, but I hope, and really pray, that Hollywood doesn't star Robin Williams as

Looks to me Japan-style price deflation is taking down prices of engineered bicycle components everywhere. Shimano isn't the only component-maker trying to prop up prices to stay alive.

I'm starting the process of redoing my 14 year old touring bike, and changing from Suntour 7 speed to Shimano 9 speed in the process. The rear is spaced at 130mm.

I have a 1965 Jack Taylor Sports Tandem that I recently aquired. Upon tearing down the frame and taking some measurements, it appears that the rear dropout spacing is 126mm!

Someone on sci.engr.mech said a chain sprocket system was over 95% efficient at transmitting power -- better than a belt drive.

I'm guessing most of the friction is between the pins and the links as they wrap around the sprocket. The friction would increase directly with rpm and with tension in the chain -- in other words, the % friction would remain constant over all power ranges.
