absolutely not. have you any idea how much technology goes into those

decades.

it's basic materials. morten's right on this - aluminum can mean
thicker more dent-resistant tube.

I attended a presentation by the head engineer of the can department at
Anheuser-Busch (as part of a class).

A tiny per can savings in manufacturing cost adds up when one is making
hundred of millions of cans per year.

Aluminium (alloy) frames contain poor quality beer?

Jobst rides a very large frame, at least 64cm (25"). He is an experienced
enough cyclist to have realized that the chainstay should have been
replaced rather than patched. Even better he should have used another
frame and not have set out on such a demanding trip with a frame that was
likely to fail.

Have a read through Thomas Stevens's "Around the World on a Wheel" from
1887 or whenever it was. That part of the world was very difficult then
for the Western tourist. OTOH Dervla Murphy had an extremely positive
experience cycling across the Middle East alone in the 60s. I think
that much depends on random chance (when you go, what's going on in the
political climate etc) and how you approach people.

Dear Chas,

Well . . .

"Then I saw that the right chainstay had separated about 30mm ahead of
the dropout. This faulty tube had broken at midspan about two years
ago, and was splinted and brazed."

http://www.trentobike.org/Countries/Europe/Tour_Reports/Tour_of_the_Alps/1995/3.html

It sounds as if the original brazing repair lasted two years.

I suspect that Jobst may still be riding the same welding-repaired
frame. This picture shows (I _think_) the welded area:

http://mly.smugmug.com/gallery/1895371#125761100-O-LB

(from http://mly.smugmug.com/gallery/1895371#125761100 )

When Jobst returns from his current tour of the Alps, he can let us
know if it's the same frame from 1995 and whether he had the tube
replaced or is happy with the repair.

Jobst's description in the second paragraph of his tour descriptions
didn't change the frame details in 1994, 1995, 1996, and 1997:

" . . . the frame is steel and about 26" with oversized top and down
tubes . . ."

http://www.trentobike.org/Countries...our_of_the_Alps/1997/Tour_of_the_Alps_97.html

http://www.trentobike.org/Countries...our_of_the_Alps/1996/Tour_of_the_Alps_96.html

http://www.trentobike.org/Countries...our_of_the_Alps/1995/Tour_of_the_Alps_95.html

http://www.trentobike.org/Countries...our_of_the_Alps/1994/Tour_of_the_Alps_94.html

In 1996 and 1997, the opening heading was "How and what I took along
(Same story as before)."

For what it's worth, here's a Honda trials machine frame, welded at
what would be roughly the seat post on a bicycle, if bicycle seat
posts split into an upside-down Y:

http://i12.tinypic.com/6329bww.jpg

Gas tank on the left, rear fender and dual suspension frame-loop on
the left.

It broke clean through about 25 years ago when I foolishly pretended
that I was back in timed competition and had a wonderful time blasting
up and down a familiar mountain trail. So far, the repair has lasted.

Cheers,

Carl Fogel

Please notice the weight of the frames i'm refering to. In denmark a
lot of riders has dent's in their aluminum Principia Rex's as well -
hoverver those don't weight in at 1700g, they weight arround 1200g.
1200g gram oversize aluminum acts as beercans as well as 1700g steel
frames.

I've never owned an aluminum frame and i never will - i'm just trying
to explain why a cheap aluminum frame makes more sense than a simialr
priced steel frame.
Secondly im trying to explain the weaknes of stupid light and
expensive steel frames, because somebody in this group ofte compares
those expensive and stupid light steel frames to cheap aluminum frames
in the same weight rage.

Since most bicycles never get ridden anywhere near the amount that your
friends ride their bicycles, aluminum is "good enough" for most buyers,
and much more profitable to the manufacturer.

You wouldn't want to buy an aluminum-frame bicycle if you're a frequent
rider, though some people get away with it for years.

Steel is overkill for the usage that most bicycles get, of a few miles a
week, if that. The metal fatigue of aluminum will never be a problem for
the casual rider.

I think he would have replaced that chainstay after the 1995 failure.
But more recently he's mentioned rear dropout failures (which is why
he swtitched from 6 speed freewheels to 7 speed cassettes). I think
the photo above shows a dropout replacement.

*(Actually yes- Boddington's and Tetley's are a couple of them).

Wow, that's a big inner chain ring that Jobst has. He definitely gets

I'd like to know too. It makes me feel less silly for having a 46&38

Dear Smokey,

Jobst is notorious masher and uses a 50/46 x 13/24 six-speed:

"I used Avocet Road 700x28 wire-bead, non-Kevlar tires on 36 hole
Mavic MA-2 rims with 1.8-1.6mm DT spokes; Campagnolo Record brakes
(Kool-Stop red pads), small flange hubs with a SunTour new winner pro
6-speed FW 13-15-17-19-21-24, Sun Tour Pro derailleur and downtube
shift levers, and Shimano Dura Ace 180mm cranks with 46-50 CW . . ."

Cheers,

Carl Fogel
