New Bike Time
I picked this up last Friday. It's not a replacement for my other off-road bike(s). I simply wanted it.
It's a single-speed, rigid, 29er. I think you're supposed to say, "Twenty-niner." The rims are the same diameter as 700c. The difference is that this frame is built to accept huge tires -- like the ones that are on the bike. They measure 53mm wide and 29 1/4 inches in diameter. 26 inch bikes have that kind of width, but their diameter is only 26 1/4.
I apologize for the different measurements, but in the U.S., we're stuck between the English system and the metric system. I relate to both and am constantly caught using both systems in one sentence. Don't blame me. I represent the current situation. It's like being bilingual except not as useful.
The reason this tire size is useful is that the bigger wheels allow the bike to roll over rough terrain more smoothly. A bigger wheel gets stuck in fewer small bumps. I've ridden a few of these as test rides at shops. I also rode an un-named riding companion's 29er in Wisconsin a couple of weeks ago. I'm convinced they ride more smoothly over bumps. But mostly, I'm convinced that new bikes are fun -- even if they're old, new bikes. Like the old bike that got me thinking of this wheel size in the first place. The Raleigh DL1 3-speed with 28" (635mm bcd) wheels.
I sold an old road racing frame and fork last night and still have another for sale. These sales are to keep the bike supply in balance.
Rigid: A bike with no suspension.
29er: 700c with extra fat tires and a frame built to accommodate those fatties.
700c: A wheel size that most road-racing bikes have.
Off-road bike: Any bike you ride on dirt trails.
Single speed: A bike with one gear that also allows you to coast, that is, it allows you to stop pedaling while moving without being thrown up in the air like a rag doll.
