than people who can lay CF, especially over a fractured piece of CF?
I've heard there's a lot of people in the surfboard(?) and kayaking business who do that kind of stuff regularly.
Me and my bestest mate have both cracked our Ti frames.
😥
Was there not some CEN test for frames?
Ah yes thats where the BS that cynic-al mentioned for BS EN 14766 came from.
carbon has been chosen on fishers sugar and c'dales scalpel specifically because it CAN flex. All about engineering, rather than supposition innit.
I am no expert
at last. And all agree that the original quote is BS?
Of course you can say something like that, If both were brand new materials with no prior knowledge then fair enough.
al, you are right and i am wrong. happy? 🙂
Pretty easy to find CF repairers-

Quiet day in the bike trade bad weather causing everyone to have SAD too it appears. 🙄
Nope. Day off. And sunny for running.
Retailers arguing on the web isn't very good for company image is it though?
Don't think any of you buy owt off me anyway!
Arguing?
More like discussion non? Lack of spoken tone will make it look like arguing I suppose. Point taken.
as we all know nothing is ever constant in the MTB world, so i can never say for sure that Ti would do something the CF wouldn't. But for me the Ti would likely take heavy impacts better, and whilst i realise Ti is quite brittle as a metal Ti would bend rather than just give way, like i have seen CF do. I am sure some people have seen Ti give way, though i would say that is very rare.
Does the ti frame come with a book on carbon fiber myths to reassure you in your purchase?
Don't sell niche 29er fixies with bar mounted pipe holders then Spokes? 😀
Lol at rs
It's jus healthy debate 🙂
Not even a surly hipflask in our shop. I think the most nichecore thing I have is one of them orange sticks with reflectors on to keep cars away from you. It's been there since the punic wars.
Who'd buy a Jo Burt themed pipeholder off us, though?
Oi I have hipflasks. But ain't niche.
Did you get hame ok btw?
orange sticks with reflectors on to keep cars away from you.
i want it - no-one on here has one of those. oooh i can see the thread now. everyone will be so excited - i might even fit it to my funny sized wheeled fixie mountain bike!! 😉
Yeah, I have returned to no bikes, nothing to do and bugger all in the fridge. So I've been playing on here and watching Dave.
It's not too disimilar to the heady world of bike shop staffing 😉
Heh I am on laundry and housework duties but hurled my left foot on run so on couch 'taking the weight off it' of course.
Where are your bikes anyway?
Who'd buy a Jo Burt themed pipeholder off us, though?
me
(if it's Ti)
(or carbon - whichever's stronger really)
Well, I have the road bike, but I've done about 600 miles on it in 4 weeks and if I have to place my head below my arse again before October I'll be reet grumpy.
The others are at the guy who drove us to Moray's house and the Evil needs a headset fitting. I'll be back on the bike tomorrow evening though.

Carbon fibre bike lasts 17yrs, shock horror!
Back in 93 I really want one of those or a Kirk Magnesium 😯 Now there's a frame material.
Lol. Apparently the test is whether a bike will last under Dawn French.
What's the conversion factor for one French in Nm?
met a bloke the other week on a GT plastic bike (sts ?) that must've been well over 10yr old. said he rides it every week (California, so dry but even so, pretty good going)
Fatally, however, it's not a LT hardtail - thus inadmissible 🙂
WTF? Have I entered the twilight zone whilst reading this thread? I do like the sound of that bike with the pasta frame though!
Tubes formed from pasta sheet and filled with custard's is the next big thing
Yeh, how did Lenny stand it so long?
the past bike filled with custard would provide a good argument for the person who's horsey friend in a thread the other day said at least if my steed breaks down in the middle of nowhere i can eat it to survive.
well I've got a broken titanium frame, an Airborne Lucky Strike. a 'friend' succeeded in splitting th top tube where it joins the seatpost.
the reason given by a frame builder was the force put on that area by the frame's extended seat post design. I was amazed at how thin the tube was at that point. Any frame is only as strong as the design coupled with the quality of manufacture. Ti is another material that can be used and is generally very durable. I shall have to see how long my other Ti frame, an older Airborne Lancaster which is a much more traditional design lasts.
Si: I'm sure people have long since stopped caring, but
I'm still not clear as to why the statement is BS though
People (al) were calling BS because of the "titanium will last a lifetime" line. As you pointed out, Ti has certain characteristics which, if used well in a design appropriate for intended use, is likely to last a long time. Same could be said of CF, but they will both have certain pros and cons that will have more to do with the design, build and use than the material alone.
'Ti is magic, anything made from it WILL last forever' is a bit too far from the truth.
"titanium will last a lifetime" - maybe it's the waranty terms ?
"lifetime warranty" that sort sort of thing?
We absolutely promise this thing will continue working until it stops working.
I've got a couple of carbon fishing rods, one of which is well over 20 years old, the other a bit less (17 ish?) and both are still fine.
Conversely, I have a couple of titanium fishing rods. Both of them are shite.
From this we can conclude that carbon trumps titanium.
Can't we?
WTF, does fishinig have to do with bike frame design?
Are the stresses then same? Are they as complex? Could I co fishing with my carbon frame? Would I catch fish?
As far as lasting goes: a good well designed, well made frame of any material will just as long as any other. However once things start to get lightweight that changes for all materials. Effectively they aren't designed to last they are designed to be as light as possible and just barley cope with a set of designed loads. Exceed thoose designed loads and the frame will break, no wmatter what its made of.
Thats why companies such as intense have frames labelled FRO and there are designed to last just one seasons racing. Look at other companies you will find that the lightest stuff as the least warranty length especially if you race, no matter what the frame etc is made of. Thats becuase its built to be light not last.
attack top tube with cheap hacksaw for 20 seconds. See which one is perfectly rideable after. I'd imagine, in a lifetime, some scrote will probably have such a go. I don't think there is such a thing as a frame-for-life, too many variables in life that you cannot predict. Piano could land on it.
