Do magnesium sliders on my mtb forks count? Which brings me to a downside of using steel bolts in magnesium holes: it can be easy to strip the threads in the hole if you aren't careful enough - I know this from experience!

I purchased a Vaast A/1 frame and built it up with XTR drivetrain, Paul Klamper calipers, and Thomson hardware. I really can't tell the ride difference compared to carbon, but being the bike nerd I am, I just had to get one. I haven't crashed it yet, but I did drop a pedal wrench on it without any issues! The price (about USD $1200) made it a good value.

American Classic used to produce magnesium bike rims, among the lightest rims ever produced. The corrosion issue didn't suit rim brakes but, disc brake rims avoid that issue. I hope someone starts producing magnesium rims again soon. A low section, magnesium clincher rim weighed 290 grams, that's 100-200 grams lighter than the average alloy rim.

As a car enthusiast I can add that magnesium alloys were also used in 60s/70s top level motorsport. Magnesium wheels were rather common in the scene at some point, and some race cars even had magnesium alloy tubeframes. They were abandoned due to fire hazards, but that's obviously much less of a concern in bicycle riding, so it makes sense to be used there. So I guess the only reason to pick titanium over magnesium is corrosiveness?

@larrysavage2920 2 года назад

FYI, Had a customer bring a magnesium frame in that he had bent the rear triangle on, while backing up in his garage on a rear rack, at first I thought it would be like Aluminum, unable to cold set, Leonard Zinn of VeloNews told me it can be done just like a steel frame. With a little effort it we realigned it. (Paketa bike)

Would love to see Vaast put together a Mg alloy prototype bike that includes a frame, but also Mg rims, hubs, seat post and collar, handlebar, stem, fork, cranks and « fenders » as Ollie calls them. Then, have him ride this for 1000 km on all sorts of terrain like hill climbs, gravel, TT, in rain, snow and shine. Finally, do a follow up video on the bike. Curious to know if such a bike will be a Vaast improvement over existing bikes.

A Bicycling magazine article from back in the 80's was about the future of frame materials. It basically predicted that future bikes would be made from materials from declassified military skunk works projects, composites such as lithium metal matrix etc. Like 14 speed prediction from back then, look at how long it has taken us to reach that point.

@roye2479 2 года назад

Somewhat correct. Skunk works gave us Ti alloys which eventually found its way into bicycle, same with metal matrix composites, carbon composites, etc. Also, Allite makes a Mg alloy using declassified recipes

The lightest or least dense metal that is a pure element is lithium, which has a density of 0.534 g/cm3. This makes lithium nearly half as dense as water, so if lithium was not so reactive, a chunk of the metal would float on water. Two other metallic elements are less dense than water.

I have the Vaast A1 and LOVE it! It rides and feels a lot like a nice carbon frame. It’s super responsive and definitely very compliant. I’ve only got a couple hundred miles on mine but I’ll post more details here when I’ve got some serious miles on it. I test drove one here in New York and loved it so much that I traded it in for my Cannondale Topstone 5. The A1 is about $1000 less expensive than the Topstone 5 and honestly I much prefer it.

Maybe when I buy my next bike in x years there will be more magnesium bikes available, would be cool.

These Science shows are fabulous, one point I would raise though is the use of Beryllium. Being an old person with a long memory, I recall in the mid 90s one frame builder produced a single beryllium alloy frame. It cost somewhere in the region of tens of thousands of dollars and was a complete one off, due to the difficulties of working with the material. I have no idea if this frame was ever ridden, I suspect it went into some rich person's personal museum.

@feedbackzaloop 2 года назад

With regards to precision enginnering, it opens the question if is it also precision manufacturable. With thermal expansion higher and conductivity lower than aluminium, magnesium calls for greater disturbances in weld areas. And no, vibration damping is not about the magnitude of Young modulus. It is about difference in Young modulus at compression and decompression. What VAAST are actually saying here, the frame acts like a softer spring compared to an aluminium or titanium with same tubing. It smoothens the vibration by shifting their frequency, but it doesn't affect the corresponding energy. Yes, "basically ... it's more compliant", but frame stiffness has always been more influenced by tube thickness and dimensioning rather than the chosen material.

Bought myself a Vaast A/1 not long ago. It's a seriously good bike, and for a while the pricing on it was outright insane: I got my 1x11 Rival hydraulic build with Stans wheels and a carbon crankset (!) for just $1700. Not to mention, it was actually in stock and available for online ordering, which was a miracle in current times. I would like to note something on the video: right around 10:30 you mention that magnesium, as a more compliant metal, can be softer and more flexible in a bike frame. You also mention that alloys can make up for this. Strictly speaking, this isn't really true; assuming the geometry of a given frame stays the same, how soft or flexible it is correlates directly with how compliant it is, and both correlate directly to the material's Young's modulus. (By geometry, I mean things like the tube profiles and shapes of the joints, not things like stack or reach or top tube length) You can't make this theoretical frame stiffer without also making it less compliant, and the only way to accomplish either is to alter the Young's modulus. Alloys in general cannot alter Young's modulus significantly compared to the base metal, so it's not correct to say that you can make a bike stiffer and less flexible while keeping the same compliance simply by using an alloy. So, put in simpler terms, theoretically a frame made out of pure magnesium and an identical frame made of AE81 alloy will have practically identical stiffness and compliance characteristics. The alloy improves neither characteristic. However, the difference is that the pure magnesium frame will almost certainly be too weak to ride, and may fold under you as soon as you sit on it. (The same thing applies for pure aluminium vs aluminium alloy, pure iron vs steel, and pure titanium vs titanium alloy) Instead, what you can and should do is alter the geometry of the tubes and joints outright. By, say, flattening out certain parts of a tube, or using different wall thicknesses on different sections of tube, you can change the flexibility of the frame on different axes. That's how the so-called "lateral stiffness and vertical compliance" is achieved in isotropic materials such as metals. (Carbon gives you more options with the orientation of the fibers.) Sometimes, these changes will require certain alloys to maintain the same strength or fatigue standards, but the benefits found for increasing stiffness while maintaining compliance are still a result of the tube and joint shapes, not in the alloy. This is why hydroforming aluminum is such a common practice, and why tube butting is used on so many different metal bikes.

I considered Mg frame and bits in the past, turned out the problem with frames is they had little fatigue resistance, ie. they're more likely to crack than Aluminium. Pretty kool material though.

@marceljanssens5935 2 года назад

As does a carbon frame....

@simonm1447 2 года назад

@@marceljanssens5935 I think it depends on how much reserves the frame has. Carbon is very strong in fiber direction, and as a fiber material it has not the classic fatigue of a metal. However, fiber materials can delaminate if they are under stress, and the resin can age and is not UV resistant like a metal. If a frame is built with as little material as possible it will fail over time, independently which material is used

You need to use a blue flame which is super hot to set a light to the frame

@stevengagnon4777 Год назад

Excellent presentation.. sweet.. simple and nailed it securely. Magnesium certainly has come of age and hopefully become a reasonably affordable and easy to find choice. One kilogram not bad and the ceramic coating included all the better. Its about time. Is this going to hold up in salty coastal and winter roads better than steal ( steal holds up okay in the rust belt but you better use some frame saver and stick to the heavier gauge stuff... a lot of mantainance plus the bike will be heavy. Those coastal bikes should also get the frame saver treatment as they can rust from the inside out and sneak up on you with a bunch of dead tubes that thud and don't ping when you flick it with the nail on your middle finger) and aluminum (my experience aluminum isn't that great ... I've had to call a few costumers and let them know that their frame had some holes under that blistering paint near the bottom bracket and head tube ... carbon fiber just foolish) if so then there is an excellent material for the four seasons everything bicycle. Looking forward to some more scientifically detailed expansion of this topic... more chemistry, material science and engineering.

incredible methal, i use to weld magnesium some decades ago, when cars use magnedium wheels. Today aluminium alloys are a better option for car wheels. For road bike i think its a nice option.

@The1trueDave 2 года назад

I can see how the crystal structure might affect the vibration dampening but I'm not sure it is directly related to Young's Modulus. YM is basically the 'spring rate' of the material, so that's like saying a softer spring will naturally damp vibrations more. It won't, you still need to introduce damping some other way... In the case of the material this might be via 'hysteresis', the energy lost as the material springs back into shape. If the material has higher hysteresis there will be more internal resistance against its springing back and this would probably have a damping effect on vibration...?

"cheaper than titanium" These Vaast frames seems to be pretty on par with some of the titanium offerings, and I haven't even found another company making magnesium bikes. where in ti there are lots of brands some definitely way more expensive than Vaasts offering, but some cost way less. Maybe the raw material is cheaper and more abundant in the earth but doesn't seem to relate to the price of the product.

@galenkehler 2 года назад

Carbon fiber, aluminium and titanium were ridiculously expensive when they were first introduced, I'm willing to allow that the price will come down when Mg achieves the same level of prevalence.

@jamesmcguckin6288 2 года назад

@Alex-to8es 2 года назад

@@galenkehler It won't. Aluminium is cheaper and more abundant in the supply chain, Carbon is better but more expensive. Magnesium bike frames really don't have a place in the market, much like titanium bikes don't really either, they are just niche products for the sake of it. You can make an argument for Steel touring bikes being repairable by any off the track shop, but even that is a bit tenuous given the alloys used in higher end ones. This is exactly what it says it is, an Ad. If you want cheap and robust it is a Aluminium, and formally Steel, if you want top end performance, it is Carbon. If you want a fashion piece, maybe go with Magnesium, Titanium, Bamboo, or even wood.

@cjohnson3836 2 года назад
