should get a 28" MTB steel frame

WTF does that mean, if anything?

I've read there are even 29" MTBs in the US,
forgot the brand tho. I read the cycling press
in the public library cover to cover (well, the
parts on technology at least) but I don't
subscribe so I can't look it up either. It was
mentioned a couple of months ago. (Perhaps
there are 29" MTBs in other countries as well.)


In the USA almost every mountain bike sold today is 29". 26" mountain bikes are hardly sold except maybe at WalMart. 29" is simply a 700C bicycle rim with a 1.9" or 2.1" tire on it. Measures about 29" diameter. 700C road wheels with 23mm or 25mm tires measure about 26.5" But calling your bike a 26.5" isn't very popular in the USA I guess. But saying you have a MANLY 29 INCH mountain bike is macho I guess. Saying you have a 700C mountain bike rim with 2.1" tires isn't too appealing I guess.




Speaking of MTBs and the US, I also read that
the original MTB was simply a single-speed with
a coaster brake and wide tires. On my military
steel bike, which has a Torpedo 1SP rear hub,
I have these tires


front 56-584 27.5 x 2.20 650-56B
rear 26 x 1-1/2 x 2


So I suppose I have an original "US MTB", only
with a Swedish frame, and a German hub!

But obviously the bike wouldn't do in anything
that resembles a "mountain". Too heavy and no
gears: even too heavy for any puny inclination
in the wild or city alike!

635mm format is, in my experience 1-1/2x1/5/8
only. Nothing wider, nothing skinnier
available anywhere.

635, isn't the modern 28" 622? Well, I have the
following data on 635 [1].


635 700B B = 2nd revision
44-635 28 x 1-5/8 x 1-1/2 old-school "V rim"
40-635 28 x 1-1/2 700x38B


The "V rim" is my personal designation where
the rim has the shape of the letter V and all
the spoke holes are on a single line (not
left/right interchangeably like one is used to).
I don't know if this makes the wheel less
strong and more difficult to true?

Yes, you can buy a classic British 28" bike:

Save for the color (black), that looks great!
But doesn't that have the save problems as my
military bike? No gears and too heavy?

A classic British 28", is that this BTW
