King Cage - Bottle Cage Failures

Hello,

A while back I put 2 King Cage (www.kingcage.com) stainless steel
watter bottle cages on my regular road bike. About a month ago on a
ride the seat tube cage broke at the bottom mounting bracket weld. Now
inspecting the other cage it is about to fail as well in the same
manner. Looks like metal fatigue.

Have any of you seen this before? Other than the durability issue
these seem to be nice cages.

Are there any other stainless steel cages that are more durable?

Thanks,

Steve

Dear Steve,

residual stress was a component. see the way the cage has sprung open?

That's a completely different situation: cheap Chinese/Taiwanese
product, different material

actually, it's completely analogous. if the tubes are not formed
correctly so there's residual stress within the structure, and the welds
are bad, it's going to break regardless of whether it's stainless steel
/or/ aluminum.

Dear Carl,

Someone has defaced my copy of "The Reverse of the Medal," where the
Royal Navy officers, Jack and Mowett, explain to the surgeon and his
clerical assistant, Stephen and Martin, the difference between
men-of-war and privateers:

"But is not a water-bottle-holder a bottle-cage?" asked Stephen.

Jack and Mowett pursed their lips and looked disapproving. "Why," said
Jack after a moment, "I suppose strictly speaking you could call them
bottle-cages, aluminum bottle-cages; but no one ever does."

"Some say bidons," observed Mowett. "It sounds a little better."

"I know nothing whatsoever about water-bottle-holders," said Martin.

"Why," said Jack, "they are metal frames made out of aluminum in the
Far East. They can be used to hold bottles filled with water by riders
who don't appreciate the advantages of a bottle-cage. They often work
well, but cannot compare with a steel bottle-cage."

"So it is very much like a bottle-cage altogether, except that it is
made out of aluminum?"

"Oh, no," said Jack. "It is quite different."

"It is not at all the same," said Mowett.

"I have often heard water-bottle-holders referred to with strong
reprobation," remarked Stephen. "As, 'Aluminum dog of a
water-bottle-holder, go your ways.' It is certainly a term of
reproach."

"Forgive me if I am obtuse," said Martin, "but if both steel and
aluminum frames can hold water containers, I cannot see the
distinction."

"Oh, it is not at all the same," said Jack.

"No, no," said Mowett. "It is quite different."

"You are to consider, my dear sir," said Stephen, "that the
water-bottle-holder is merely concerned with carrying water. Whereas
the bottle-cage is chiefly concerned with weight and wind drag and
their bottles are often flung aside near the finish line."

Carl,
To quote a posting you directed at me:
Begin quoted text:

I couldn't think of kindly way to put that, so I'll try to reassure
you a little.


Vitamin C prevents scurvy, so just drink some citrus juice, right?
Limes, lemons, what's the difference?


"By the 1850's, it was deemed preferable to give Admiralty money to
English gentlemen growing limes in the West Indies rather than to
foreign lemon-growers in the Mediterranean. This decision was a
disaster; the supposedly similar fruits in fact retained dramatically
different amounts of vitamin-C, and scurvy returned with a vengeance.
Ships that relied on lime-juice and still suffered from severe scurvy
were all the evidence that was required to damn Lind's
recommendations."
http://www.historyscotland.com/featu...wasalemon.html


The same page points out that an 1850 British polar expedition drank
lemon juice and suffered no scurvy.


But in 1875 another British polar expedition drank lime juice instead
of lemon juice and suffered from scurvy.


In other words, it's tempting to think that two things are alike,
measure one, and make conclusions about the other.

yup. I had residual stress from two first BC failures then hooked the
third with a shock cord, other end tied to Grant's Tomb now muh Third
Hand 3 in one split fur no good reason.
Remember those 350 Yamaha welds....those were the days.

Carl, Jim,

Residual stress seems to be an issue with these as well as the
asymmetry of the one side of the cage is significantly different from
the other side.

Heh.

If I wanted a high-falootin' bottle-cage, I'd build
it myself out of heavy gauge brass wire.

If I wanted a high-falootin' water-bottle-holder I'd
use sheet brass c/w fretworked motifs -- probably stuff
that incorporates nice skull designs.

Traditional cycling jerseys with the three rear pockets
are perhaps one's best bet. The left pocket for tube-food,
the right pocket for hydration, and the middle pocket for
one's nuts.

However,
some stuff has to be mounted on the bike (to keep the rider
lighter,) and some stuff has to be mounted on the rider (to
keep the bike lighter.) So the bike gets to wear the water
bottles in their flimsy retainers, and the rider gets to wear
the Godiva chocolate bars in their flimsy retainers.

Maybe that's how it should be.


cheers, & hydrate or die, or enjoy a Godiva chocolate bar,
Tom

Remember, those bottle cages (or braze-ons) are used for a lot more
things than just water bottles:
