I've had one of [url= http://shop.ebay.co.uk/luckynino/m.html?_trksid=p4340.l2562 ]these [/url] Ti cassettes from ebay on my 29er for 9 months, last week on a local ride, just climbing up hill, the chain jumped off the rear into the spokes, Stopped to check the bike out and the largest Ring was bent.. but worse, the spider that mounts it had snapped... pretty piss poor after 9 months and really not loads of use.
Emailed the guy on Ebay and he said "like all cassettes" there is no warranty to replace them in the event of failure. Surely this isn't normal ? pretty piss poor considering the the price of these units.. I'll stick with SRAM or SHIMANO in future as at least they would replace a defective item.. miffed...
it's a fault thats known on weight weenies.
I've seen a (XT I think) Shimano casette snap a big chunk of a few teeth off. It's not common, but it does happen.
9 months is a good life for a lightweight cassette
singlespeed inint? seriously though, id be miffed too. I'll stick to my nice pink ali spidered sram one (that will never wear out as it's used once a year at best and sits in the parts box until then).

bugger.

for the spider to snap ? Yeh, rings wear out / bend etc.. but spider snapping is just a bad unit surely ?
BTW, I'd say ive owned this for 9months, its on my 29er HT that I've not ridden as much as my Full Sus bike, maybe 200 miles in that time...
Seller told me,
C'mon. You ask for a 12 month warranty on such a high wear item?
As mentioned i sold hundreds of these cassettes over the last 5 years and never ever had something similar happen.So please understand that i have my doubts that it's the cassettes fault. It is definitely not a manufacturers fault but might rather be a case of bad circumstances out on the trail.I am still sorry to hear about but i really don't see any warranty case here
Wouldn;t you expect at least the first question he should ask would be, "shit - sorry to hear that - can I take a look at the cassette first and take it from there ?"
It is definitely not a manufacturers fault
For a man to divine that without seeing the item, thats impressive.
or bollocks.
Its all a little suspicious, his instant reaction was denial.. and my first contact with him regarding this was so polite... I think.. its happening quite a bit for these judging by his reaction.
O well, live and learn, Sram next time.
ouch, my Alfine cost about the same as that, probably a bit heftier though
Shimano warrantied my XTR cassette which wore out after 200 miles, no questions asked.
lucky nino is worse than susperstar for customer services.

Don't worry your not the first...............but luckily since he got kicked off a forum for selling his expensive better than everyoneelses though obviously proven wrong shite in every forum post
I've bent quite a few SRAM cassettes and on another SRAM a sprocket actually snapped in half.
had teeth break off a shimano but from a mech/chain/hanger killing impact.
Lighter than XX, cheaper than XTR, there was a clue... 😉
I've often considered buying one for races, but no one seems to say they last!
a) it was bought from ebay - expect most of your 'rights' to be relinquished right there
b) its made of Ti. Ti is soft as cheese.
they are recon cassettes
So please understand that i have my doubts that it's the cassettes fault. It is definitely not a manufacturers fault
he's right, your chain jumped the cassette which indicates the indexing was off, which is maybe also why it was shifting shite, chain went into the spokes and stopped the wheel, force broke the cassette,
how is that a manufacturers fault?
Or else the sprocket gave way, letting the chain ride over into the spokes and snapping the spider as it folded overhe's right, your chain jumped the cassette which indicates the indexing was off, which is maybe also why it was shifting shite, chain went into the spokes and stopped the wheel, force broke the cassette,how is that a manufacturers fault?

id bet you a million million pounds my version is what happened
ironical they cost more than a xtr one
b) its made of Ti. Ti is soft as cheese.
based on what measure exactly? Have you ever tried to cut Ti? Have you ever thought why Ti frame fabricators cut with fluid jets, and why 6Al/4V tubes were often made from rolled sheet not drawn like conventional tubing? or why F1 cars used Ti skid plates?
Titanium alloys are so much harder than Aluminium alloys they are measured on a different scale.
Titanium cuts nicely with conventional tooling .Tubes are cold drawn even 6/4 titanium tube
You can get titanium to be harder than steel by using oxygen and a couple of other clever tricks ...
ever cranked out of the saddle on a thin tubed Ti frame? If so you would have noticed it wobbling away between your legs (the frame that is).
I would bet a billion million dollars I could fold a Ti cassette ring before a steel one.
ironical they cost more than a xtr one
They don't... XTR is more at retail, admittedly they can be had cheaper though.
Ti sprockets wear faster, hence only the large sprockets on XTR/Dura Ace are ti, and on these Recon cassettes the 11t is steel. Sprockets are also more flexy, so the shifting is worse.
Titanium alloys are so much harder than Aluminium alloys they are measured on a different scale.
That's irrelevant when cassettes are made of steel. Alu cassettes are really crap, purely for the scales!
slim, you are mixing physical properties and concepts. Ti is hard (ie. difficult to cut or dent) but elastic (i.e. flexible). You said it was soft. Former research metallurgist pedantry.

😀
composite, Litespeed used to roll sheet and weld to make their 6/4 tubes rather than try draw them (the original Ocoee when they first introduced an oversized 6/4 downtube to combat the flex).
What amazes me is that the large cogs on cassettes aren't folding in their zillions. They're so skinny now with 10 speed blocks.
Ah - thanks for the heads up on these - I had them down as an upgrade when my current XT wears out- not any more LOL

With the vast majority of the force the cogs have to endure being applied by the chain in a plane virtually parallel to the cog surface then why would they fold ?
wiggly spider

Who said the shifting was shite ? Where do I collect my money ?
Honestly, this thing just caved in. I've had many other cassettes where chain has jumped into spoke and its NEVER failed. This think is simply not for purpose.
Stripped it down today and I was wrong about the spider, its the ring itself that's cracked.. there appears to be a week point where there isn't much metal, just behind the teeth.
These end up being interpreted in every which way but, here is a pick anyway.

Maybe it's the pic, but that looks utterly worn out anyway.
Bin, buy a real one.

That's what I thought, I'd expect trouble if it was as worn as it looks up there.

You might want to learn how to adjust a rear mech!
Whats the old saying? [i]A bad workman always blames his tools...[/i]
"Lightweight Product in Longevity Shocker!"
I'm waiting for the next installment, where simon posts that his soft compound tyres have worn out too quickly.. 😯
Really, if you want to have a pop, read the f'ing thread.
Im NOT, and never have complained about wear, or bad shifting, I'm complaining about the thing cracking.
Is it really worn ? Honestly, this has been on my 29er that I've ridden Max 250 miles since Nov last year, its set up with my Hamax childseat mount on it as most of its duties have been carting daughter up and down cylce tracks !
You gotta laugh at paying nearly £150 for a cassette. (no smiley)
My bike had an XTR on it when purchased and the Ti spider wore out [i]before[/i] the sprockets. What a silly way to save weight.
Huh? The spider is aluminium, it's the sprockets on it that are ti.
XX cassettes are >£300, [i]that[/i] is daft.
Fair point Dez but, if done well, XG999 etc, there shouldnt be a week point on the cassette. Wear is wear, fair enough.
My point is that there is a design fault with this cassette.
All the other rings, 32 downwards don't have the metal removed at the point they meet the spider, however this 36 tooth ring does... its a design flaw.
How did it come off the cassette? Did you not set the hi/low screws? Or am I missing something? Entirely possible!
Also what are those cassettes like? Are the ranges with the 36/11 still good?
As the old adage goes:
strong, cheap, light. Pick two.
[i]Huh? The spider is aluminium, it's the sprockets on it that are ti.[/i]
The XTR definitely had a ti spider.
a 36t cog is asking for trouble
How did it come off the cassette?
I think the sprockets has broken first kicking the chain off. I've never had an issue with it going into the spokes before.. and yet all maximum limit screws were set.
Strangley, the guy this morning has admited responsbility.. but, said I don't deserve it so wont replace it ! He's done this on the basis that I've given his shite products a bad image on here and MTBR... which I did do, after he initially said, without even seeing a picture of the damge, sod off !
Shimano / SRAM - you both need new departments wherby you only offer Warranty to people who don't bitch about your products when they fail, get some one tralling the itnernet for complaints BEFORE you pay out 😉

Nino perchance?
The XTR definitely had a ti spider.
They really don't - it's an alu spider, with 5 ti sprockets, same with Dura Ace. Alu = lighter than ti, a ti spider would achieve nothing at all.
I'm talking 2006. No way that was an alu spider or it wouldn't have worn the splines
It seems it did. They've always been alu spiders, M953s, M960, M970, M980 - I've had several of each!
We need Mister P!
Nino perchance?
yup.
I tried the consolatory approach today.. and to be fair to Nino.. He's agreed to send a replacement outer part of the cassette.. fair play in the end.. shame I had to go through the ringer first but his initial reaction was as I thought the spider had gone.
Alls well that ends well I guess...
