Steel or alloy frame?

I've looked for the FAQs etc on this group but can't find any. Sorry if this question irritates
anyone but I would welcome advice on whether I should buy an aluminium frame or steel frame. I'm
interested in a road bike to use in triathlon so I'm willing to part with a reasonable sum. I've
noticed that cheaper bikes tend to be aluminium and the better ones steel. I've heard that
durability can be an issue with aluminium. Is this still a major drawback? And is the ride quality
on a steel frame really that much better?

Thanks,

Michael MacClancy

I think expensive ones are very often aluminium as well. Regarding ride quality other factors other
than material come into play, you really need to ride them to see what suits you. Last summer I
replaced a Columbus SLX (steel) bike with a Cannondale aluminium one. C'dales are legendary for a
harsh ride and it certainly rattles more over cattle grids than the old steel one which was super
smooth but overall on a longish ride it's great.

To put the debate into context last year Cycling Weekly and Cycling Plus both independantly tested
the same, very expensive, Cannondale model. The CW tester said it was so uncomfortable he couldn't
wait to get off it while the C+ tester commented on the great ride quality and said he could ride
it all day!

They were both talking through their asses. NOBODY can tell, blindfold, what he's riding as regards
materials. It's been tried. It's all (and little else is) in their heads.

Eh? I'd like to have seen that. How long did they manage before they ran into the hedge?

Sorry I've been busy and not paying attention. First I have never ever owned a frame that it has
been worth while repairing. It has always been a better option to buy a new bike complete with shiny
new group set. Usually the need to replace comes upon me because the paint gets tatty and the frame
rusts - average age to require to refinish a steel frame has been 5-6 years at which time the group
set is usually knackered as well. OK the Bianchi didn't make it but one sample isn't likely to be
representative of all alloy frames or makes. Guess the answer is - don't know. I've now got a shiny
new alloy frame, am still using my 653 racer of 9 years old and have a £99 tange frame for audax 5
years old and beginning to look its age - basically buy more bikes that's the way to happiness.(god
how sad is that I retract).

Oh and someone on the thread doubted the bar room stories of cracked alloy frames - well it's in the
garage now want a photo? Mike

Yeah, but "steel is real!" To put a little bit of an aside, I commute/do very occasional audax, and
wouldn't swap my steel frame Dawes for aluminium, and notice that most tourers/audax frames are
steel. I'd guess that would be for the extra flexiness/comfort on less then perfect roads. In
shorter distances/race circumstances, aluminium seems to be the way to build a stiff frame.

Of course, somebody is just going to throw a spanner in the works by mentioning carbon or
titanium. Whoops!

Absolutely :)

And I have had a steel frame repaired: it was about half the price of a new frame; repair and new
forks was just under half the price of a new bike. Dawes Super Galaxy, mid 1980s.

Pete, for me this is the stuff of nightmares - I might be riding along on a very busy road, and the
next minute I'm flat on the tarmac with an artic lorry approaching. Is there anything one can do to
spot the warning signs of such fatigue - perhaps there is some gizmo that does an x-ray of the tubes
to spot any visible change? Or should I just be fatalistic and accept that there's a vehicle with my
name on its number plates?

To paraphrase: it's not the one with your name oin it you need to worry about, it's the thousands
with "to whom it may concern"

Slightly off-topic but I think Extra Terrestials are just inter-galactic sex tourists. This is
because whenever you read reports of alien abduction the abductees aways state that the aliens
messed about with their reproductive organs.

OTOH they might just be naturalists, after all no tv nature programme on Earth is complete without
some time devoted to screening the subjects mating, so we have something in common with aliens then,
a fascination with the lower specis' method of pro-creation
:)

There's probably a deal of truth in that - I wonder how many of the stories passed round date back
tyo the days before framebuilders knew what they were doing with aluminium?

LOL :) Just as well I'd actually swallowed my mouthful of coffee before reading this or I'd have a
mop up job to do.

Wash it Guy. A decade and more ago aluminium masts were the performance choice for windsurfing, my
own one lasted all of 3 years before breaking due to corrosion <1> which was easy to see around the
fracture. This despite little sea use (used fibreglass for that) and regular rinsing in fresh water.
OTOH my 11 year old bonded alu Trek mtb is sound after having all sorts of **** thrown at it due in
part to thorough cleaning I think.
<1> Barring accidents fibreglass and more modern carbon reinforced masts last indefinately.

I thought this might be the case - aluminium tends to suffer surface corrosion relatively quickly,
but I've not seen it eat in like tinworm does. My car has an aluminium tailgate, and you
occasionally see them with the paint blistering where it's been scratched and salty water has got
in, but I've never heard of it holing.

On the other hand, the tubes on bikes aren't *that* thick and al. oxide is definitely not a
strong material.

Jury still out, perhaps?

Apart from the chassis, which rusts with monotonous regularity :)
