Perfect for hilly Seattle and I live on a steep hill.

Since before the turn of the twentieth century, the development of gearing systems for bicycles has inspired a vast amount of technical invention and innovation. The overwhelming variety of drive train styles has been the subject of many articles and several books, and new developments continue to appear. One goal that has obsessed inventors almost from the beginning has been the creation of a continuously variable drive system. There have been many attempts to build such a system, which would allow the rider to change the gear ratio throughout the range without being limited to specific gear increments. Until now, all the imaginative approaches to this mechanical conundrum have been either completely unworkable, or inappropriate for use on bicycles.
Great Tour for Discovery Channel, taking 1st overall, 3rd overall, the team competition, the white jersey, and two stage wins.
But it was an even better Tour for US frame manufacturers, who swept the jerseys and two of three podium places.
Discovery Channel was responsible for much of that success on Trek’s Madone and Equinox TTX frames, with Contador in yellow and white, Leipheimer in 3rd with a win in Stage 19’s time trial, and Yaroslav Popovych in 8th on the overall classification.
One of the most liberating things about Bettie is the big tires; Big Apples from Schwalbe to be exact. They’re like that cruiser bike you had as a kid, where you just roll over everything: through a field, over a curb, on gravel, potholes … whatever. They also have a magic carpet ride about them and Schwalbe calls big-apple equipped bikes, Balloon Bikes. Not sure how that marketing program is working, but we’re seeing bikes with big tires on The Ride, Batavus Diva, and even Dahons.
Big tires are cool, bigger is better, but what I’m don’t know about is the 650B wheels (which measure 27.5” in diameter, half-way between 26” and 29” wheels) discussed this week in Bicycle Newswire.
Question is whether or not the world needs another wheel size?
