How To Break a Carbon Frame - and Almost Two

- Last year in Klosters on the Gotschna Freeride track (they call it the Swiss A-Line) we crashed badly. The bike of Ben hit a rock which led to a hole in the upper tube of the frame. He then caught mine. Else it would have hit the rock too. When you approach this section you suddenly realize that you have to go left slightly. But then you are on a sketchy wood which is already a right turn. So the left turn is completely off camber.
The markings on the wood show that there where others struggling here. I saw videos where others just managed it because they where approaching the section some few cm to the left from our line. - Sport
That view on the second clip tho, wow.
that feature needs to be adjusted. this ain't right that you guys went down like that
Yes. I saw this quite often in Europe. They build obstacles which don't work out well or are even unnecessarily dangerous. But it often takes years till they become improved or rebuilt. On a difficult track there can be dangerous obstacles like big jumps. But then you get something - airtime for example. But if a something is not even a feature but just dangerous than it should be improved.
Hey Downhill Rangers! Glad the injuries were not worse than they were! Stay safe! Ride ride ride!
Thanks!
I was here 2 months ago, literally the same happened to my riding buddy...
Sorry about the crash but why is the trail being blamed? It appeared to be a pretty normal downhill track….
They need to have clear signage so this doesn’t happen. No bueno for the bike..
That’s not what mtb is about, you want signs get a road bike.
which bike is carbon? the blue bike or yours?
Both, Giant Reign (blue), Santa Cruz Nomad (mine).
Hab auch ein Carbonbike und ziemlich viel Angst vor sowas
That's why I avoid carbon in my bike. 1 fall or debris out of the wheel, which happens all the time and frame is done. ;/ I heard it's easy to fix but still, with alu I don't have such problems. Carbon frames are ok for road bikes.
Stones from the wheels should not be an issue. What I've seen are bigger rocks flipped with the front wheel. But I think then it's not a carbon only problem. I once had such a situation where the rock then hit the rear mech which then was torn off completely. So the screw of the derailleur broke, the cable tore and also the cage. Video: czcams.com/video/n70zxBAPgBw/video.html I have to admit that some frames come with too little down tube protection. We where pretty sure that in the crash in this video a aluminium frame would have also been damaged. The tubing of aluminium frames are often quite thin. I'm sure that there are crashes or falls where a carbon frame is damaged and an aluminium frame probably not, but in some cases also vice versa. Furthermore when aluminium frames where rather new they broke a lot. Far more than carbon frames. I had cracks in two aluminium frames, until now none with the carbon frames. But I rode aluminium frames for 18 years and carbon frames only for 8 years now (but I rode the carbon frames much longer than the aluminium ones).
@@DownhillRangers stones from the wheel messed up my YT frame.. Carbon is just a marketing gag for mtb/emtb. So many disadvantages for the few grams saved..
@@leonaRt7470 Everyone can have his own opinion. Manufacturers put more and more decent protection on the down tubes. I have seen soo many broken aluminum frames. I have no numbers but I would not say that carbon frames break more easily than aluminum ones. Surely they have different weaknesses. It always depends. If you don't care about the last grams saved - go for aluminum. But a strong aluminum frame is easily 500 g heavier.
@@DownhillRangersyh, just get a steel frame
@@peterwillson1355 Remembering the times when I bent a steel bar after multiple "drops" of a 40 cm wall - to be fair it was over 30 years ago. No suspension forks back then
That feature NEEDS TO BE WIDER or have a berm right there. Wow
You can tell this is a common problem by the exposed dirt to the right of the wood
Is the carbon frame ok?
It had quite a crack in the top tube. But a friends works at a company which manufacture carbon parts (e.g. for motor sports) he fixed it. Without telling you wouldn't notice that it had been repaired.
Did you ride the day after with the same bike?
@@wittedave81 I did, but the friend riding in front of me with the then broken frame hat a second bike with him.
@@DownhillRangers I think the worst part about repairing carbon frames is fixing the color after. So annoying
@@LinkinPark4Ever1996 I have not actually done it myself. A friend who repairs carbon frames can use his comapnies paint shop. Also he has a plotter for the decals etc. Probably that makes it easier.
I think they were supposed to stay on the bridge
Die mit dem Minus auf der Fahne, könne halt nöd velo fahre!
Drum hämmer auch es Plussi auf der Fahne!
daher fahre ich nicht in der schweiz, da ist man in allen bereichen nur aufs langsam fahren spezialisiert...
Schaut so aus. Wir waren ja beide schon in Whistler und kennen die echte A-Line. Die ist relativ schnell und für die größe der Sprünge ziemlich safe! Keine Fallen, breite Landungen, keine kickenden Sprünge, Holz auch nicht wirklich (ist aber schon 10 Jahre her bei mir - hat sich vermutlich seither schon wieder einiges getan). Mit A-Line hat der Gotschna Freeride nix zu tun. Im Nachhinein haben wir gesehen, dass es sowieso sinnlos gewesen wäre, die 1x zu fahren. Da sind einige Sprünge mit Gaps drinnen, wo man einige Zeit verbringen muss, bis ma da Spaß hat (zumindest wenn man net Profi-Hüpfer ist).
that hand looks broken. I hope you got a cast
I was able to ride the next day (on smooth trails). Then after a two weeks brake from mountain biking it was pretty much ok again. So no cast.
don't skip too much ahead, thing happen 20 seconds in
Carbon breaks aluminum bends. Either way your screwed. 20+ years ago I fell over crossing a stone wall and bent the rear triangle of a Jamis frame I had.
i would rather have a bend than an instant break if my life depended on it
@@nathanpecson9008 Long time ago there was the same discussion with steel vs aluminium. In the early years of downhill biking I saw a lot of broken aluminium frames. Not only bent ones. Surely there are crash situations where a carbon frame would be superior and others where the aluminium frame is superior. And of course it's always a matter of the particular model and weight.
aluminium generally doesn't bend but cracks
Was wohl mit einem Alubike passiert wäre? czcams.com/video/FpwvXDwUY58/video.html
Sicherlich wäre das Rahmen total verbogen, oder?
Im mittleren Bereich der Rohre sind Alurahmen meist ziemlich dünn. D.h. es hätte da schon eine massive Delle gegeben. Der Carbonrahmen wurde übrigens von einem Freund, der in einer Carbonfirma arbeitet - und schon einige Rahmen repariert hat - wieder repariert und neu lackiert. Wenn man es nicht weiß, sieht man gar nicht, dass was gemacht wurde.
Wenigstens ist außer dem Rahmenbruch gesundheitlich alles einigermaßen gut ausgegangen. Keine Sicht auf das schräge Northshore Element und dann noch blankes Holz... Ziemlich fahrlässig!
Ja, sehen wir auch so. Sicher kann man immer sagen, dass man auf Sicht fahren muss. Aber wir waren eher langsam. Beim ersten Table waren wir viel zu kurz. Und bei der Anfahrt zum problematischen Teil hatte ich mir noch gedacht: wenn das ein Sprung ist, komme ich da nie auf Airtime - aber schneller geht nicht, wenn man nicht weiß was kommt. Dass dann Holz kommt, aus der Richtung ist und nach außen weghängt, damit kann man echt nicht rechnen. Holz ist einfach so rutschig und schlechter kontrollierbar im Vergleich zur Erde. Auf unseren Hinweis, dass sie da was machen sollten, haben sie gemeint, dass die Strecke halt nicht für jeden ist. Stimmt zwar - unnötige gefährlich ist die Stelle trotzdem. Ich hab's auch schon bei anderen Parks mitbekommen, wo gefährliche Obstacles nach Unfällen nicht zeitnah entfernt oder umgebaut wurden - und das nach Querschnittslähmungen. Weil das könnte als Schuldeingeständnis bei Versicherungsfragen interpretiert werden. Traurig. Umgekehrt habe ich gehört, dass z.B. bei Parks in Whistler nach dem Bau von neuen Features die Shaper die Fahrer beobachten und wenn's nicht passt, wird nachgebessert. Bei uns stehen suboptimale Obstacles oft jahrelang - bis halt wieder mal ein Bagger vorbeikommt.
Big bills dont get ya skillz

Titanium bikes are better than carbon
I don't know of any bikes with titanium frame of bigger manufacturer right now. I know some have experienced with it now and then. But if they would be "better" surely we would see more titanium bikes. As far as I know titanium is used in some higher end cassettes for individual cogs (usually not the whole cassette) and some replace various steel screws with titanium ones to safe the last bit of weight.
Blöd wenn man nicht fahren kann 🤣🤣🤣
Nur so schnell fahren wie das Können zulässt
Only a pud would blame the trail and not themselves, we don’t act like that here in the US bro, we say “fuck it” and hike it back up for the day.
Just a reminder that cyclists do NOT own the trails! Ride with caution, take time to enjoy and respect nature.
These kind of trails are exclusively built for cyclists. There are no hikers allowed. Of course one should always check out the trail at first. But this was a built trail for mountain bikers and there where multiple unexpected changes at once: suddenly wood - which is much more slippery and unpredictable as dirt. It was a slight turn to the left, but the wooden turn was off-camber. And I have never seen an off camber turn on such a trail - especially not on wood. And even if there was dirt on the left - like a berm - there was a gab between the wood and this dirt hill. So even if we thought we where just checking out the trail to see what to expect we where a little too fast or a little too far right. There where also a lot of skid marks on the wood - most likely from other riders which had similar troubles.
@@DownhillRangers All riders should proceed at a safe speed. Foolish to assume a bike is going to just ride itself. But I can see in the video the wood did appear slick. Soon Ill be riding my first carbon fibre bike, and looking for information as to how much the bike can handle, I am used to something a little more than cross country riding, some drops and jumps, mainly urban, like 3-6 concrete steps. 2-5 foot drops, not sure my bike can handle much.
@@DownhillRangers P.S., my original comment was not actually meant to the even in your video, but to remind riders to take it slow and enjoy the ride. Back in Albuquerque NM where I am from, Riders are Extremely rude and are always trying to claim the trails as theirs alone. They will run hikers and walkers out of the way and never stop, instead they shout out and just expect people to move out of their way, I do not like seeing people be such assholes to each other , however mountain bikes have done just that. They would rather risk hurting a pedestrian than have to break and build up speed again. Its no wonder road bikers are such hated people. As riders we all need to maintain good reputations by knowing our place.
@@VEHICROS This video is from Switzerland, Canton Graubünden, where mountain biking is allowed - where it's not explicitly forbidden. I'm from Austria and there it's the other way around. Mountain biking is not allowed at all - except where it's explicitly allowed. Usually only in tourism regions which want to attract mountain bikers. So as a general rule we always have to wait and let the hikers pass. But here it's often a difficult situation. Hikers see you as somebody who breaks the rules and as some sort of threat. But what many hikers don't know: 45 years ago it was not even allowed to walk in privately owned woods - and most of the woods are privately owned here. But when this was changed there where no mountain bikes and vehicles of all kinds where excluded. Besides hiking only skiing is allowed here. In Italy, where mountain biking is allowed, it's completely different. Hikers are often amazed by your skills on difficult trails than see you as a threat.
Sorry - that was me - with the wrong account.
