Hi Hazzardlight - welcome to the forum .
What do you ride - are you a roadie?

This is why I say look at the actual words and what they mean. These warranties are legal documents, words and phrases often mean quite different things in legal terms.janiejones said:Good point Steelem - and a lifetime warranty on Giant's Alu; Alu/carbon & Carbon, the same as Orbea.
These companies are massive businesses - into bicycle manufacturing for the money, they are not going to be making something they need to replace free of charge every couple of years.
A bicycle is useless without pedals. Your logic implies that if a bicycle is sold without pedals, then it is not covered for use with pedals, how would a user actually use their bicycle? Is a warranty only applicable if the item is unusable for its intended purpose?threaded said:This is why I say look at the actual words and what they mean.

Life-time often means only for the ownership period of the original purchaser and when used for the purpose it was sold for. These things have loads of caveats i.e. if you bought the bike without pedals that means you are NOT warranted to ride it on the road!
Hmm, possibly a better one than you... it gets springier, but at the same time the limits of elasticity become narrower. i.e. over time it will deform under a lesser load, and at the same time will break under a lesser load. Get a alu spoon and try it.HazzardLight said:Which school of physics explains the phenomenon of being springy and brittle at the same time?
I feel you're being a little facetious here. A bike sold without pedals is not warranted for use on the roads, and everything that entails, i.e. being outside subject to the weather etc. Obviously doesn't mean completely unused, but I would take it to mean only for track racing.nerdag said:A bicycle is useless without pedals.

I think you're reading far too much into the legalese.
Your comments about product lifespan seem to reflect your (mis)understanding of the legal terms in the warranties, rather than real world experience with the durability of the materials.
FWIW, I've been using one of my aluminium bikes almost daily for commuting over the last two years, and the frame is still holding up fine. It doesn't look like its going to disintegrate anytime soon.

A spoon is not a tubular structure, and therefore inherently weaker.threaded said:Get a alu spoon and try it.
1yr for parts - frame its 10years as i statedthreaded said:Did they? Really? I think you'll find they say something along the lines of: components are warranted against manufacturing defects in materials and/or workmanship for a period of one year from the date of original retail purchase.
Please provide counter proof.
So, what you actually mean is that its natural elasticity becomes weaker; ie: that is it loses elasticity; not 'it becomes springier'. This loss of elasticity is directly related to the increase in brittleness?????threaded said:Hmm, possibly a better one than you... it gets springier, but at the same time the limits of elasticity become narrower. i.e. over time it will deform under a lesser load, and at the same time will break under a lesser load.

How would you use a bicycle on the track without pedals, if what you say about them being sold without them is true?threaded said:I would take it to mean only for track racing.
Some racing cars (I am thinking F1 here) have carbon used in their suspension systems. But they cost a sh!tload, and they serve a particular function on the cars. Apply a force to them that was not intended, and they'll snap very easily.threaded said:Look at it another way: what cars have carbon fibre or aluminium wishbones?
This is an unrealistic comparison.threaded said:Look at their warranty: replace every x thousand miles or y months whichever is the sooner.
really sorry i got this wrong just checked my purchase details it should be - 1yr parts LIFETIME WARRANTYsteelem said:1yr for parts - frame its 10years as i stated
So, you get a crack in your frame: see how far you get arguing the difference between a manufacturing defect and a fatgue failure. Do a Google, I'm sure there're lots of people whinging about this distiction on Cannondales and the other manufacturers that similarly use fancy words.steelem said:1yr for parts - frame its 10years as i stated
This is quite a feisty forum!! I thought since I joined the thread, I'd best comment.. but unfortunately, I ride MTB.rparedes said:I am beginning to create a wish list for a new road bike...maybe $1,800 to $2,400 range for good performance, smooth ride, hard training, riding steep hills and rolling terrain, maybe 4,500 to 5,500 miles per year and probably to keep for a long time....Any thoughts will be greatly appreciated.
regards
Yes a spoon is a different structure, yet you do see the effect I talk off and much quicker.nerdag said:A spoon is not a tubular structure, and therefore inherently weaker.
Quite easy for me, although it does tend to hurt for a few days.I suggest you try to bend an aluminium tube on a bicycle and see how easy that is.

MTBer too. I did the Merida MTB Marathon (103km) in Hillerød, Denmark yesterday. Now that is a perfect way to find the limits of bicycle structures and materials. Presta valves: that little threaded piece with the nut on the top of it is just not strong enough when you're jostling for the lead and get a puncture.HazzardLight said:Hi Janie,
Thanks for your kind words. No roadie; MTB for me. Dust, dirt, trees, birds....that's for me.
Is that you in your avatar?
Yeah, mountain bikes are cool - I'm thinking of getting a cheap one just to cruise around on - some of the Giants look good.HazzardLight said:Hi Janie,

i gotta a cannondale - few years old now - but still a brilliant bikejaniejones said:Yeah, mountain bikes are cool - I'm thinking of getting a cheap one just to cruise around on - some of the Giants look good.
No that's not me in my avatar, hope I didn't disappoint you.
Doesn't it seem as though the overall IQ of the forum has severely plummeted as of late? It's like I've entered some warped and twisted Twilight Zone episode, where nothing makes any sense at all. It's simply a wasted effort trying to explain your point, however logical it may be, to those who absolutely refuse to listen.alienator said:I guess all those folks riding around on aluminum Cannondales from 90's are accidents waiting to happen. And all those folks on Cannondales from the 80's must have death wishes.
I guess the same could be said on the 2 or 3 folks I see riding around on their 90's vintage Cadexex. Gee, I guess they didn't know that their CF frames would only last a year. If they had, their frames would have broken up long ago!
