On One Ti 456 cracked!

My 2009 on one ti 456 has developed a crack by the head tube after only 16 month. I bought it because all the hype says a Ti bike will last forever. I didn’t realise “forever” was such a short time!

The great news is that it has a lifetime warranty and so it is back off to Lynskey for repair or replacement.

On one have been pretty good so far having arranged collection swiftly.

Anyone else had a ti 456 problem?

Yes. Twice.

But plenty on here said I was somehow making it up.

A few, yes.

On-One is being pretty good/sorting you out, etc, so perhaps a little impolite/unfair to start a thread about one of their frames breaking?

Because they are honouring their warranty you can’t discuss the issue in an open forum?

That must be the small print that no-one reads.

Heard a few stories about other manufacturers as well. Is Ti more or less reliable than other materials? Are people just more likely to post if it’s a ti frame due to it’s “frame for life” reputation? Quite tempted by a ti frame so am curious.

I would have read the OP as a positive one, not a negative one.

You’re new round here aren’t you? 😆

Ti is just as likely to break as any other frame material. However it won’t corrode or lose its ‘springiness’ as much as steel or aluminium.

I’ve ridden my wife’s 456 Ti extensively and I’m a heavy bugger. I’m also not known for my finesse.

After several years of this, the frame’s still fine; I’m confident that if it cracks, On-One will sort me out.

I have broken a Ti hardtail frame. Lifetime warranty does not imply the frame will last forever!

Nothing lasts forever, it’s the nature of the universe, but it does imply that the manufacturer believes most will last a very long time as it costs them to replace/repair.

Lifetime warranty…does imply that the manufacturer believes most will last a very long time

‘Most’ being the key word.

Just like every material, it depends entirely on how it’s made.

Steel does not lose its ‘springyness’ does it? It just fatigues so flexes more and more until it snaps.

does it?

you could argue it work hardens until it’s brittleness causes failure, if you were a metallurgist….

From what I know of the Ti 456 (I think I might’ve been the first person to break one – luckily at the back end not the head tube, unluckily after having it for about 2 months) and Ti in general (I work as an engineer…), I think the problem is twofold.

1) The bike companies hype up the durability of ti frames – so people expect the frames to last as long as the hype says.

2) The bike designers maybe believe the hype a bit too much themselves and push things a bit too far when speccing Ti frame tubes etc.

As above, Ti frames can last a very long time, but so can a well made steel, aluminium or carbon frame. And it mostly depends how well designed and built they are, not on the theoretical benefits of any of the materials.

To be fair to On-One, none of the other stuff of theirs I have has broken (over a much longer period of time than I ever had the Ti 456), and that includes 2 steel frames, carbon forks and a fair few aluminium bits. They did also replace the frame quickly under warranty. I’d definately buy something not made of Ti from them again.

From other people I know who’ve owned a variety of Ti frames, they seem no more likely to last you for life than anything else.

I managed to **** my 456Ti frame. I spoke with On One and after trying to ‘fix’ it sent it back to them and they passed it on to Lynskey. It was returned fully fixed for a small fee covering postage/insurance etc and a new rear d/s triangle.

Only downside was that it took the best part of 4 months…, but then it was me that had knackered it.

And can we just stop this expensive frame crap, compared to the average FS, they are not expensive.

errr…

That’s true but generally unless your frame flexes loads(I mean massive amounts), then a steel frame can easily last a life time.

I’ve never had a problem with a ti 456. This being mainly due to the fact that I’ve never had a ti456.

i have cracked a lovely ’boutique’ ti frame too – twice – they arent indestructable – but a joy to ride!

On one 456- if u feel u gotta have one, dont put a 6″ fork on it, these frames are xc only! If u dont break it, yer not riding it hard enuff baby! 😆

Err ok.

I can’t tell if this post is sarcastic or not. You do know the idea behind the ‘Inbred 456’, right?

+1 with John Taylor…..4″, 5″, 6″….thats what its designed for right ❓

P.S. Ive thrown mine down most of what the Lake District has to offer and yes i may be 65kg but i dont ride it like Boris Johnson…(asuming he actually does ride a bike)…….

and it`s fine.

😉

yes i may be 65kg

Are you some sort of anorexic? I thought I was light for my size, 6″1′ and about 70kg. Unless your short?

No, just lean….. 🙂

Steel and titanium have fatigue limits, which means as long as the material is kept below a specific stress/strain it will never fail via fatigue no matter how many cycles it is put through. For steel this limit is approx half its ultimate tensile strength.

Aluminium doesnt have a fatigue limit so even small cycles of stress/strain can eventually lead to fatigue failure. The reason aluminium bikes had a reputation for being stiff was down to manufacturers using large diameter tubing to prevent flex (= strain) under load (= stress) to stop the frame failing via fatigue, not because of the stiffness of aluminium itself.

So steel and titanium dont flex more and more til they snap, but aluminium does.

Titanium frames usually fail as a result of contamination during welding.

and yes i may be 65kg

65kg? My knob weighs more than that! 😀

Ah yes. Mine has failed along the weld,

On one have been pretty good so far having arranged collection swiftly.

Its a shame that the phone calls & emailed photographs of my cracked year old Inbred have not elicited the same response. Having to foot the bill for sending it back myself, & waiting a week now without so much as an email or phone call to update has dimmed my veiw of On-One somewhat.

Glad to hear most folk experienced better CS than I have. 🙁
