broken canyon cf

crapaudthepitbull

Hopefully someone can shed some light on where i stand in relation to frame breakage. I have/had a canyon cf which i had purchased in April of last year. A good friend purchased the frame in the UK as i was away on work and i collected the bike from him on my return home
4 days ago the rear hanger broke off whilst going up a hill sending the rear mech into the back wheel then ripping into the rear dropout. The frame is therefore f***ed. I have sent Canyon various photos of the damage and they have stated that the best they can do is offer me some sort of crash replacement, although i hadnt crashed or even knocked the frame. The chap i spoke too was very polite and explained their side but i still feel there is a warranty issue here or am i kidding myself.
If anyone can fill me in with any advice or previous experience it would be gratefully received. Thanks.

Very hard to say without photos.

If I'm understanding you right, the hanger broke initially, not the frame, right? And not as a result of anything defective about the frame?

So a part you didn't buy from Canyon, and fitted yourself, broke, and damaged the frame.

If so, I don't see how you have a claim against Canyon. Sorry, I can imagine how frustrating it must be, but there it is.

Huh? Hangers come with frames. However they don't generally break spontaneously. (Although a manufacturing defect is conceivable.)

I would have a search around this forum as its not the first time I have heard of this on Canyon CF bikes.

Can this be merged with the 'Mavic Wheel failure' thread?

as above, it doesn't sound like canyon's fault, assuming the offer of a crash replacement represents a good discount it's more like they are trying to be helpful

you say the hanger broke off first, is there some reason to think this rather than: the rear mech caught in the spokes, then the hanger broke...?

going uphill hard in low gear is one of the times the rear mech gets closest to the spokes

the hanger is canyon's, assuming everything was set up correctly and the hanger hadn't had a bash then a warranty claim could be justified, but you'd need proof of the chain of events

Ah, do they? I've never bought a frame on its own. I thought the hanger was a replaceable part that was bought separately.

Best advice is to get your friend to keep on at them, staying pleasant, and see where he gets to. The bike is pretty new, so I'd expect to get it replaced if it's in warranty... however, like I said, it's all down to your friend if he paid for it, not you, noone would honour anything to someone who's not the person on the paperwork, so forget talking to them yourself.

Thanks for your reponses.Just to clarify the rear mech must have got caught in the spokes which inturn ripped off the rear hanger sending the rear mech into the dropout. The gears were well adjusted and this is the first time there was any hint of anything wrong.If it was a cheap 2nd hand buy of ebay i would leave it but this is almost a grands worth of frame. For me now its a simpler case of goodwill from Canyon.

Forgive my ignorance, I don't understand how it's possible for both of these to be true?

poppit

Without something breaking or the rear mech being incredibly badly adjusted i.e. the stop screw being totally backed off, I don't understand how it can hit the spokes.

Either the rear mech wasn't adjusted correctly (L- limit screw) or the hanger was slightly bent (in transport/storage?) before the ride.

mfin

You can't slightly bend a hanger enough that it would throw a mech into the spokes the second you reached lower gear. In fact, with adjustments, you'd find the chain would come off the biggest cog well before the mech pushed itself into the spokes.

The hanger almost certainly broke, when this happens its really common for the mech to be pulled into the spokes, my mate had the same thing happen twice in a couple of months.

They don't break spontaneously, but it's easy to knock them and cause enough damage to weaken them without noticing. Then when you're just riding along they can break with no warning. I had this happen once. Mech was nowhere near the spokes (middle of cassette), I wasn't changing gear at the time, but the hanger broke. Luckily I stopped pedalling straight away and stopped quickly so all that was damaged was the rear mech. I think I was lucky.

Not a hope in hell of blaming this on the manufacturer though - it's down to damage (inadvertently) caused by the user.

You're really digging deep to place the blame everywhere except where it belongs...

How about cutting your loses? Unlikely to get the warranty claim you hope so what about a repair? HQ Fibres should be able to fix it for you for around £100

Known in the trade as a JRA or "just riding along". 99 times out of 100 the customer is adamant that a component simply fails spontaneously and catastrophically of it's own volition?

Perhaps more than slightly, then...
It's a classic scenario where you start climbing hard, down shift a few gears in one move and you have a mess in a second...

Something to bear in mind, between us my wife and I have had 4 mech hangers break on our Canyon MTBs, all without any impacts, as such I've replaced them with hangers from here http://www.pilo.co.il. They broke next to one of the bolt holes where there isn't much metal.

The hanger on my wife's Ultimate AL road bike has been fine so far but I check it before each ride. If you've got an expensive carbon road bike it might be worth replacing it for piece of mind, they come in nice colours too.
