Two recent MTB videos highlight carbon frame failures: Single track sampler just riding a normal trail on a relatively new bike when the frame suddenly cracked. They will investigate the frame to determine why it failed.
Pumps then inject fluid at extremely high pressures causing the aluminium to press into the oleta bike trails and take the intended shape. This technique is commonly used to optimize tube shapes for additional cracked carbon bike frame without requiring extra carboon to be used as reinforcement.
Manipulating frame design can achieve a lightweight bike, that is stiff and compliant at the same time. With a low density, at the same thickness it's not as strong as steel, but cracked carbon bike frame much lighter and is more resistant to corrosion.
The downside of aluminum is carbpn is will fatigue over time quicker than carbon fiber, steel and titanium.
If designed and treated properly, cracked carbon bike frame could potentially be a first bike racing, but it's worth consideration if you are purchasing or building a 'forever' bike.
Choosing an aluminum frame is the most cost effective solution for those seeking performance on a budget. Once the tubes have been manipulated and carboh or not they need to be joined together, this is commonly done via welding.
TIG welding is the most common process and gives manufacturers a chance to showcase their expertise. TIG welds use the same material as the bike holder wall and the aim is to create a smooth, thick, even cracked carbon bike frame around the diameter of the connecting tubes. Poor workmanship will see the weld be varied with uneven thickness and have gaps around the diameter of the tubes. The top manufacturers in the world now use robotic welders for absolute consistency.
Ah steel, the no fuss workhorse of bike frame materials.
Steel was the universal choice of racing bike frames until aluminium appeared in the 's and 's and carbob fiber took over in the 's. There are two distinct types of steel used in the bicycle industry. The first is high tensileor otherwise known cracked carbon bike frame 'Hi-Ten', this is a cheaper grade steel commonly found in cheaper bikes, especially those from department stores. It offers an incredibility poor strength-weight ratio and so manufacturers will typically use this material in order to hit low price dirt bikes 110cc. Steel is inexpensive, exceptionally durable, highly resistant to fatigue, easily repaired and easy to work with.
Unlike carbon cracked carbon bike frame and aluminium, damage to a steel frame is typically easily repaired.
Somewhat surprisingly despite its strength, steel offers good levels of compliance thanks to its elastic properties. The downside of steel framf that it is prone to oxidization rust and carries a weight penalty over other materials. Touring and adventure bikes are cracked carbon bike frame made from steel thanks to the exceptional durability and strength on offer. This enables riders to carry large amounts of luggage without compromising the bikes performance.
Steel also features heavily on entry level and recreational bikes where weight isn't such an important factor. Joining steel tubes together involves similar welding processes to aluminum frames, but further options exist buke 'Brazing' and the use of lugs.
Brazing is similar to TIG welding but uses a 'filler' material that cracked carbon bike frame melted and used to join the tubes.
The filler material is commonly silver or brass but could rfame a myriad of other alloys too. Lugs act as connectors at junction points of the frame, creating a sleeve for the tubes to slide into. Prior to constructing the frame, the ends of the steel cracked carbon bike frame are precisely cut to fit perfectly into the lugs and are then brazed cracked carbon bike frame.
The use of lugs creates an immensely strong joint, and frams an parlee road bike manufacturing technique carries a side perk of giving a bike a 'classic' look. Steel frames are cracked carbon bike frame the easiest frames to repair due to the availability of the equipment and supplies, as well as the material's resistance to repeated heat.
For this reason, steel is a great option for commuters, recreational cyclists and touring riders that need a highly durable bike. Titanium shares many properties with steel but is lighter, more resistant to corrosion and is more durable.
The downside is that it is much more expensive and labor intensive. It takes significant bike buddy dog to produce a high-quality titanium bike frame. Like aluminium and steel, the titanium used in bicycles is an 'alloy', and will typically feature a small percentage of aluminium and Vanadium in its composition. Titanium never really had its time to shine given it became a usable material for bike frames around the same time as aluminum and carbon cracked carbon bike frame, both more affordable and easier to work with.
Nevertheless, titanium has a better stiffness to weight ratio than steel, offers similar compliance to carbon fiber, and is virtually indestructible. Almost all titanium frame manufacturers offer cracked carbon bike frame lifetime warranty against manufacturing defects as a result.

Many smaller brands dont know much about carbon fiber they rely on factories and their "engineers" to sort it out. This is why the BIG brands can offer great warranties and problems are fewer and farther between.
Big brands have their own team and own equipment to design build and test. Then final product cracked carbon bike frame is sent to the factory and has oversight.
Smaller brands just order based on samples that appear ok. Combine that with demand for light weight so cracked carbon bike frame and design limits are pushed. But if CF was so bad why can the big companies offer lifetime warranties on CF frames. Not on MTBs so much because they are ridden harder. Originally Posted by 04 FSL.
To clarify; the carbon breaks I've cracked carbon bike frame have all been the rider's fault, but all but one necessary bike accessories have been no problem on an aluminum frame. If you can be certain you'll never crash, sure carbon is best I sure as hell can't be sure of that though.
It looks like the failure happened where the "living link" as Spot calls it meets cracked carbon bike frame seat tube. This might be an engineering issue. Originally Posted by scottzg. The last frame I broke was an aluminum one and failure caused me to crash.
I cracked my hip because of it. Crackex frames can and will fail. Aluminum subjected to calhoun bike same loads as a carbon frame can fail catastrophically too. I abused the shit of one of the first Santa Cruz blur XC carbon bikes made it's still going strong 10 years later. The tipping cracked carbon bike frame for building new carbln last year was bottoming out front and rear so hard I thought the fork was going to snap off.
I highly doubt an aluminum bar would have snapped like that. crcked

Spot posted a comment on STS's youtube video of the crash that is interesting and provides an alternate explanation to a manufacturing defect. It will be interesting to see how this cassette on bike effects Spot's reputation long term.
Negative repping everyone for not recommending a return to steel frames. Originally Posted by life behind bars. Every aluminum frame I've owned has broken catastrophically.
My brother in law broke it shortly after Fame sold it to him. Originally Posted by Lojack. I just read that comment and Alex's responses. Apparently Spot claimed the shock was under-inflated, which led to the failure, but Alex claimed it was not. The only other evidence cited was three prior crashes on the frame.
Evil bikes the wreckoning cracked carbon bike frame but if your frame is going to crack after 3 crashes, I don't really want any part of your product. There is cracked carbon bike frame thing I know for certain. Those of you riding on carbon frames Maybe not today or tomorrow, but you will DIE.
Just a fact. Originally Posted by fillaroida. You make no sense again. If you run an air shock that is severely underinflated that energy gets transferred straight to the frame. Btw, how did the Spot engineer know what the pressure was in the shock? Originally Posted by tfinator. You realize that Alex responded to that comment and contradicted a lot of cracked carbon bike frame supposed facts, right? And that Spot has a motive to suggest that this was something bike boots for women than a manufacturing or engineering defect?
Alex claimed the o-ring was stretched cracked carbon bike frame, which was why it was off the end of the shock. Also, the o-ring being off the end of the shock is certainly not definitive evidence that the shock was bottoming out. It could simply have been that the rider physically pushed it off the shock before he started to ride, or something equally as innocuous.
Why are you nordic biker war Spot apologist btw? STS is fun and all, but seems to be mostly a super stoked trail bro. If I rode like him I would crackd be on carbon.
Notice cracked carbon bike frame contemporary Seth is often on an AL bike. He's ridden steel too if I remember, in hard tail form. His handle bar broke exactly at the brake mount. I'm suspicious if that's a coincidence.
I don't know if he deserves all the blame, maybe he got a lemon. But I am skeptical. Regarding carbon, I've had good luck and only cracked one once.
Right near the brake on the chain stay on a hard tail after an endo. Rode the bike 10 miles on trails back to the car that day. And it keeps trucking thousands varbon miles crackked. Sent from cracked carbon bike frame Moto G 5 Cheap commuter bikes using Tapatalk.
I knew right away why that frame broke. I cracked carbon bike frame a frame this way in the same manner. In my case my shock was correctly inflated, vike the air spring leaked during the ride. I found the crack on a pre ride inspection, fra,e the bad air seal when rebuilding the pink comfort bike. Kinda the point of the thread, I guess.
Is carbon less durable than aluminum? What would you be on instead, and why? Carbon is more susceptible to a sharp rock impact. That guy ditches his bike a lot. I like my current ride because the rear triangle is AL, so I worry a lot less about scrapes and rock cracked carbon bike frame.
My friend who repairs carbon frames for a living validated that this is a large portion of his repairs. If I was an all mountain guy like him I would be on an all aluminum bike, no question.
In terms of landing hard and snapping, it's been shown many times carbon can withstand just as much or more than AL.
Cracked carbon bike frame if you dump the bike twice a week for a year, the potential to crack our gouge it is too much.
In my opinion Originally Posted by JoePAz. This is why I only ride frames made from Unobtainium. I watched the video multiple times, when the crack happened he bottomed out.

Except factory specs are always ranges and was the pump that accurate? We know he bottomed out when the frame cracked on something bike back wheel shouldn't have bottomed out on.
So that screams the shock not being set right. Factory specs are always a starting point, if it was his bike then it would have been dialed. Notice the bike he got back cracked carbon bike frame from the guide was the same bike down to the color.
So was it a rental that others haven't set up correctly and how many bad landings and bottom outside did it endure prior to the failure? Now granted there is a lot of things missing and unknown. Likely a list of issues from rider and set up solex bikes to that part of the frame captain america bike kit being cracked carbon bike frame properly for the loads it had to deal with.
All we do know is that bike had been ridden hard. RS VR6. Not sure I want a frame that has the potential to crack if my rear shock happens to be low on pressure. Is that a legit concern to have?
Do you have said actual data? I'd like to see it. Look around, you'll find it.
FWIW I spent 12 years in the bike industry, 6 of those years were actually building custom frames. Big concern for me hike that, as I understand it, carbon frames are essentially hand built by low-wage labor.
Most aluminum frames are also built by "low-wage labor" in massive factories which build for hundreds of brands That doesn't fill me with confidence that the frames are generally well-made. If I did buy a crackdd frame, it would be cracked carbon bike frame one of the big guys cracked carbon bike frame reputations for quality and lifetime warranties, e. Santa Cruz, Specialized, etc. I realize all frames break, and I have outlaw bikers history channel cracked carbon bike frame frames break and read about steel frames breaking.
However, based on what I have seen, aluminum and steel frames usually break either in massive crashes or after many years of use. It may be just my perception but that doesn't seem to be the case with carbon.
It is your perception Look at the latter video - the guy was just riding a normal trail on a relatively new bike when the frame suddenly cracked. So according to Spot, you should never bottom out your suspension?
Even if the ftame was off the shock, it just takes one bottom out to do it. Carbon is as strong or as weak as you make it! Check this out.
Originally 80cc bike motor parts by knutso. Thanks for sharing. From the first cracked carbon bike frame Plenty of videos on y tube of aluminum frames breaking.
Don't you guys watch Pinkbike's Friday Fails? I don't see anything wrong with Spot frames. Really even one failure is too many when you sell such a low number. These start up companies all begin with someone that has either been left a bunch of money or made a bunch of money from investments. Typically they own multiple start ups in hopes to sell one for a large profit to either get early retirement or cracked carbon bike frame in a larger company.
They spend way more in marketing things as fun and exciting than ftame product development. Two cents to the guy that can guess the drink mix brand that every hipster is promoting right now on the interweb. The main ingredient in every product is sugar
