how tough are carbon fibre bikes?
God, yes, and have you heard about the barbs going straight to your heart!? 😯
I think that you intended to type ‘How tough are cube bikes’ as the thread title because no one would surely be silly enough to think that all carbon bikes are the same, would they?

looks like impact damage rather than frame failure through poor manufacture, incorrect bonding etc.
When I’ve snapped a carbon frame (twice, two different manufactures) the only that looked like that was when I dropped it at low speed into some rocks in the peak.. not a big off, just unlucky.
The other, which was a frame failure due to manufacturing fault was a much tidier failPosted 4 years ago
Originaly they wanted me to buy a complete frame but that has now changed……Replacement part is £270 for the lower arm only..
Cube said it’s been hit by something which has cause it to fail.. The only protection on the bike is on the downtube.. the part that has broken has no form of protector to help deflect stones kicked up from the front wheels..
In all the time I have had the bike there have been no impacts that I would have taken any notice off.. We all hear stones bouncing off our downtubes and think nothing off it.. Obviously with carbon I am going to have to take more notice..
Should have bought a Santa Cruz.. their carbon seems to be pretty tough stuff… 5.00 onwards..Posted 4 years ago
easy.. until you try to sell an 8-9lb carbon trail bike frame )
a thin metal or even additional carbon protector around the lower half of the arm would probably have saved it from breaking.
Guess they never thought of that when they designed it..
This bike isn’t used for racing or crazy downhill events.. It’s had a pretty easy life compared to what it supposed to be capable of…Posted 4 years agotonydMember

Not sure I’d expect frame protection on a chainstay, certainly not from rock strikes off of the front wheel. That looks to me like a side-ish impact, so a rock flicked up from the front wheel and curved round the crank, pedals, and your feet (or bounced off of another rock perhaps) before hitting the bike mid chainstay with enough momentum to cause that kind of damage? You should buy a lotto ticket! 🙂
What does the inside of the chainstay look like?
In all fairness, regardless of cause I’d hope for a goodwill gesture of some kind. Is the £270 cost price?Posted 4 years agoamplebrewSubscriber

I fell 20 feet onto rocks down a ravine in Morocco on my carbon Tallboy. It wasn’t even scratched. I, on the other hand, was fecked.
Like the way the guy asks, “Did you film it?”

not very apparently.. This is my 1 month old Cube Super Stereo 160..
No dramas or youtube worthy moments in its short lifespan but the carbon lower suspension arm has failed..
Cube’s response is that its not a warranty issue.. need to buy a new arm. Not the kind of response I would have expected after buying a £4000 bike..Posted 4 years ago

The inside is still whole.. its only the other 3 sides that are split..
I was thinking I might use some of the insulation that plumbers use on pipes… the foam stuff..
I might just do the whole bike as I’m not 100% convinced that it was a fluke..Posted 4 years ago
There was a ti frame on here a while back, a local rider dented and actually pierced a ti DT, from a bit of flint flicked up by his front wheel. A rigid 29er in the chilterns – hardly heavy use riding.
You can’t protect a frame from every impact or crash outcome. Sometimes you’re just really unlucky, like this one by the look of it. Seen same kind of written-off stay on an Al susser a few years ago – very low speed wobble onto some rocks. Dented a nice steel frame’s seat stay hitting a sticky-out rock myself, no big crash needed. Sht happens..Posted 4 years ago
Must admit, when that Cube came out and they talked about it weighing 26lbs or so I thought “Two to three pounds lighter than most Carbon Mojos/Nomads, but with bigger wheels….. must be fragile”
I am beginning to think that myself.. 🙁
The sad thing it…. its a fantastic bike.. I feels perfect on the trails and goes uphill like a train..
Not much use if it breaks like a toothpickPosted 4 years ago
