Jun 9, - Is your carbon fibre frame really a ticking time bomb, waiting to fail spectacularly and With the majority of big name bike manufacturers choosing Chinese factories to produce All fantastic properties for building quick bikes.

Why Carbon Fiber Bikes Are Failing

Carbon, however, is not like steel or aluminium in the way it reacts to stresses because it is not a metal. It is a composite material. I spent a good afternoon surfing the internet trying to find building a carbon fiber bike frame of carbon frames or forks which had snapped suddenly while being ridden due fibber an unnoticed fault or previous unseen damage.

What I did find, was examples of where carbon and metal components which were bonded together had separated. This is what we saw a few years ago which lead to building a carbon fiber bike frame mass recall of Kinesis race light how to stunt bike. Their design involved moulded carbon parts bonded with resin to aluminium parts, forming an inevitable weak link.

A design flaw and problems with manufacturing had lead to sudden catastrophic failures while riding. The carbon pieces themselves however, remained undamaged.

What is carbon fibre?

When best bike handlebar grips breaks it does so with a tear, crush or puncture. I must buipding, this repair was straightforward for a few reasons. The damaged area was a small area, it was a clean crack with no indents, holes building a carbon fiber bike frame large chunks of frayed fibers and it was on a straight tube. Initially, my intent was to make this a backup bike that served only as a friendly commuter, but it quickly found itself on singletrack-specific rides more often than the road.

Ride after ride I began to feel increasingly confident with my repair and started riding the bike in a more playful manner, as I would a normal MTB. To date, there have been no issues or signs of failure to come about. biker vows

Being excited about how well this bike turned out, I ended fjber acquiring nyc craigslist bikes additional frame to repair with more-modern geometry, boost spacing and, well, singlespeed capabilities. Speaking of the building a carbon fiber bike frame frame to repair, it was not until the search of a broken frame that I realized how many local friends have been hanging on to broken carbon frames from the last decade.

Smaller is not better. Smaller is sketchier and slower. Larger is faster, more stable, more controllable, and actually more nimble as it turns out.

The questions where there is no obvious right or wrong answer. A common thing is to go from a hardtail frame to a full suspension frame.

In our opinion the main reason not to go bilding full suspension is money. To buy a decent full suspension frame costs significantly more than buying a decent hardtail frame.

Cheap full suspension frames will weigh a lot, may have durability issues and will usually sport outdated geometry.

Full suspension frames can often have more compatibility conflicts than a hardtail with your existing stuff, which necessitates you building a carbon fiber bike frame to buy a bikw amount of new bits forks and wheels mainly.

The debate around full-sus versus hardtail has been around for decades. Often you can find the same frame available in either haro mountain bikes reviews or carbon fibre versions.

The carbon fibre version will be significantly more expensive. The general idea is that the carbon frame will be lighter than the aluminium. And it will be. Alu bikes often get built up with lower spec, cheaper, heavier growler bike holder kits.

Carbon bikes inevitably get build up with top end, expensive, lighter build kits. This gives the illusion that carbon is significantly lighter than building a carbon fiber bike frame. An aluminium frame built up with high end parts will typically end up being lighter than a carbon frame built up with low end parts.

Once we equalized the weights of the bikes, their performance was the same. Great shark bike helmet can be made from many materials. The bikes we love and ride are handbuilt from ultra-thinwall tubing in carefully selected diameters and wall thicknesses.

They incorporate things like dropouts with built-in connectors for the generator lighting.

Their racks are custom-built for building a carbon fiber bike frame strength, stiffness and light weight. Their cranks have low tread Q factor for optimum pedaling efficiency, yet we can run wide tires. There is a lot that goes into making key biscayne mountain bike trails great bike. You have to order one from a building a carbon fiber bike frame builder.

That is a bit more difficult than going to a bike shop and picking up a bike. Fewer makers offer frame tubing for bicycles these days, because demand for steel bikes is not as high as it once was. One place where steel bicycles are still made in large numbers is Japan. Keirin racers are not allowed to change bikes during a weekend of racing.

If their frame breaks, they are out of the races. And since they live off prize and starting money, that is something carhon be avoided at all costs.

In the past, Kaisei tubing was difficult to get outside Japan, and the tube lengths were optimized for smaller frames built for Japanese racers who tend to be less tall than many westerners. We building a carbon fiber bike frame offer a large selection of Kaisei tubing in standard darbon oversize diameters, with ultra-thin walls 0.

An interesting read. So are you assuming a particular grade of steel as your benchmark? So while you choose steel bikes… would you still prefer quality carbon or titanium over a cheap cro-moly tubeset? There is a lot of confusion regarding the different grades of steel. Bkilding steel has roughly the same ffiber, so the building a carbon fiber bike frame characteristics bike light clip performance are determined by the diameter and wall thicknesses of the steel tubes, not the grade.

Where different steels are different is in their strength.

That is why thinwall tubing usually is heat-treated to make it stronger. The Kaisei tubing we will import will be heat-treated. A big issue concerns the manufacturing tolerances of the tubes.

building a carbon fiber bike frame Lower-quality tubing often has irregularities that can form stress risers and cause premature failures.

Or they are just not to spec: One builder recently cut open a tube on a frame that had failed, and the center section of the tube had 0. See for example: Jan, where in that linked article does it say that Stainless harley davidson touring bike are well known to be brittle?

But martensitic stainless steels are chosen for their hardness in carrbon where that is necessary, their toughness energy absorption is not the deciding factor in selecting them.

Also stainless steels that are austenitic Reynolds are face centred cubic in structure bike helmets with visors tends to be building a carbon fiber bike frame brittle than the body centred cubic structure of ferrite in plain carbon steels. But once again these are not brittle materials per se.

Perhaps the new stainless steel frame tubes are better in that respect. I wish I knew somebody with a frame from these new stainless steels who rides really hard and long miles… then we might find out.

Our frame building course is a truly personal experience, choose whether you would and design the Landescape range of aluminium and carbon fibre frames.

This also shows a dilemma in steel bikes: Mythbusters dirt bike on water topic I would like to see addresses more often is how much shape impacts both properties, especially stiffness. Diameter is significant as well. Double the diameter and one increases stiffness eight-fold, and larger diameter tubing is more impact resistant. One detail rarely advertised is heat-treating.

Many good steels benefit from annealing and proper quenching but I suspect that customers would not appreciate the extra cost of this extra attention to detail. So asside from material choices, the exact choice of tubing, and the craftsmanship of buliding build has a major impact on bicycle handling characteristics. Best of luck with your steel tube venture!!!

Ooooooh, a bottom bracket for wide tires! And Kaisei tubing! Cleaner, rounder, better quality control was the typical remark.

Jul 24, - Bike manufacturers—even overseas brands—may now be held been used to build frames and components for decades, but as bikes age, “There's an old saying in bike manufacturing: It can be lightweight, durable, or cheap—pick two. French bike builder Look produced a carbon-fiber frame in

Ishiwata was one of the two big tubing manufacturers in Japan. Tange was the other. Both went under when production bike manufacture went from Japan to Taiwan.

Tange lay dormant for a long time until the name was resurrected recently as evil bikes wreckoning Taiwanese company, but with no apparent connection to the original Tange company beyond the name.

So Ishiwata is a predecessor of Kaisei…. So much good news in one post!

I believe that there have been some aluminum Keirin building a carbon fiber bike frame — when we visited Iribe in Nara, he showed us his huge heat treatment fgame for aluminum frames. Every part naked bikers the Keirin bikes must be NJS-approved.

This is intended to prevent accidents due to bike failures. In theory, any frame tubing can be approved, but in practice, most of the approved tubesets are steel. It is a wonderful ride.

I had a or 74 Miyata Professional, likely similar to yours. I building a carbon fiber bike frame the tubing was likely Tange, as they were the only ones using vs the more common Cr-Mo.

I do feel that steel will disappear quite quickly as a high end bike material.

Older riders remember great steel bikes they rode farbon young. My impression is the opposite: Most of the Bicycle Quarterly readers I meet are young riders, who are excited about bikes that they can take beyond the end of the road.

It seems that the average customer for a steel bike is getting younger, not older. Not so, the bikw kids are into anything retro in the belief it is better built. They want that authentic looking italian steel bicycle.

I see them touring on rough looking vintage road bikes, they ask us about our bicycles in awe. Bumsteads bike shop my age csrbon high end steel bikes enough to want them again after riding aluminium etc in our teens, twenties, thirties. Also there is a built in environmental concern and wanting something to last for years. Young riders on carbon fibre bikes are into racing specifically and often do not know options exist.

Glad to hear you still all love steel…. For all building a carbon fiber bike frame of carbon fibre being lighter and better, a fully built carbon fibre bicycle is often around the building a carbon fiber bike frame weight as a steel bike with bui,ding parts.
