In the aircraft industry, a very fine layer of glass is used as a visibilty layer for crack detection. It is exceedingly difficult to see hairline cracks or stress marks in carbon, while glass has an easy to see white marks. Personally in high stress locations, I'd prefer to see a layer of glass in there.

@@Rafael-vu2xn yes, but not because it would increase cost much (a handful of dollars). There'd be a huge increase in warranty claims.

There is one more very big reason to use glass fiber in the steerer (and not elsewhere) it is that the modulus of glass is much lower but the elongation at break is much (3 to 4 times) higher. In practice, that means that in normal use the carbon is the one carrying pretty much all the load and the glass fiber will just stretch and carry very little load... But if you have a big crash or hit a big pot hole or another large object on the road the carbon with snap at something like 2% elongation while it will take about 7% elongation to break the glass fiber... That can very well make the difference between a fork that snaps off clean immediately and one that gets crushed but with the fork remaining attached to the steerer because of the glass fiber... If there is one place on a bike that you nevr want to snap off clean it is the fork steerer, guarranteed face plant... Also, do not call it "fiberglass" which usually refers to much cheaper and lower property glass fiber reinforced polyester resin used in boats while this is glass fiber reinforced with the same epoxy resin used with the carbon fiber...

I'd be pretty sure the failure model you suggest would not happen. A crash of this sort is a load dominated failure, which would cascade through the whole lot in short order. It the video is correct that sacrificial glass/epoxy being woven cloth there would be additional issues during complex bending/tension failures.

I'd love to get a "what actually matters" with these types of videos. What will lead to me riding down the road and have the frame spontaneously collapse, burst into flames, leaving me to get eaten by a tiger, vs. "it's just not perfect, but it's fine". The focus on BB area has been enlightening, the nice even circles and all of that makes sense, but what's the point where it matters? I know "fine" is hard to quantify, I'm 151 pounds and my fine may be far more tolerable than a 250 pound rider that slams ruts and potholes and such. But, give me a level of what matters on some level.

As a composites guy, I have no issues with glass fiber being used in steerer tubes. It may be unnecessary in terms of preventing corrosion if a titanium expansion plug system is used, though. As for what the frame is called, "composite" would be an all-encompassing term. I recall some high end brands (Time?) also use other materials like kevlar for impact resistance in their layups too.

Thanks for the great leg work on the F.G. in the steer tube. In the marine industry, where corrosion is a huge issue, carbon rudder posts, carbon booms, carbon masts, and carbon spin poles are all buffered with F.G. where stainless fittings are attached. The carbon will cause corrosion of the metal surfaces in short order. I just assembled a Falath frame and was happy to see your video with the FG interior of the steer tube as I used a metal tensioner internally.

Aside from stiffness/weight issues, for this consumer the most important consideration is how the use or absence of fiberglass impacts the longevity of the frame, especially regarding galvanic corrosion. I'd love to see a look back at the life expectancy of 5, 10, 15 year old carbon frames based on their choice of materials for things like bottom bracket shells and dropouts on rim brake frames.

I saw fibreglass in the steering tube of a Tarmac SL5 Sport (Fact 9). And not inside a tarmac SL5 S-Works (Fact 11).

While the depth of analysis on these frames is impressive, we are overlooking the bigger picture concerning the product and the purpose of these reviews. I would argue that these frames offer an incredibly good value for their price, as the quality, performance, and aesthetic output surpass what else is on the market for their cost bracket. As an owner of the Falath, I can confidently state that my experience with the frame has been flawless, with the exception of a minor overspray (non)issue, for my custom paint job. The notion that a small sleeve of fiberglass, which serves to prevent galvanic corrosion, is considered a weight penalty is laughable, given its weight of 5-10 grams.

Hmm interesting, I've cut two Cannondale Hi Mod steerers, a Cube and a Winspace Steerer and can confirm they are all carbon all the way through. I wasn't aware of fibreglass being used in carbon frames in the structural areas. I've heard of it being a barrier between differing metals. Nice video Cam, thanks.

Cam, love the info you are presenting here and they way you are doing it. You are really shining right now. Keep up the good work.

an official answer from an elves bike Please be reassured that having a thin layer of fibre glass inside the fork steerer is quite common in the manufacture of carbon fibre forks, at all levels, as indicated by the independent industry expert at the end of the Cam Nichols video and has two purposes. 1. Reaming of the inside of the fork steerer: The inside of the fork steerer needs to be reamed to ensure that it is perfectly round to accepts the expander plug. Carbon fibre is too hard to be effectively reamed, so the thin layer of fibre glass allows the inside of the fork steerer to be correctly reamed for a perfect match to the expander plug. 2. Galvanic corrosion. Carbon fibre and metals such as aluminium have a habit of bonding together over time. Fibre glass does not have the same issue. The expander plug used on Elves Bikes, like most brands, is aluminium. To ensure that the expander plug does not corrode and bond to the inside of the fork steerer, the same thin layer of fibre glass is used to place a barrier between 2. Galvanic corrosion. Carbon fibre and metals such as aluminium have a habit of bonding together over time. Fibre glass does not have the same issue. The expander plug used on Elves Bikes, like most brands, is aluminium. To ensure that the expander plug does not corrode and bond to the inside of the fork steerer, the same thin layer of fibre glass is used to place a barrier between the aluminium expander plug and the carbon fork tube. With regards to weight, this thin layer of fibre glass adds less than 10 grams to the weight of the fork, but the benefits to the consumer are significant when it comes to maintenance and longevity of the frame.

Hockey sticks cannot generally be 100% carbon for a host of reasons and expect some Fibre glass in the makeup. I see no reason why bikes should be any different particularly around galvanic corrosion risks. However - this is acknowledged in the specifications of the hockey stick i.e. "90% carbon" 5% aramid 5% X etc. In the bike world this is also requested or we end up with manufacturing fraud as seen here. Personally I don't care what they use, carbon, GF whatever, if it's stiff, light, and fit for purpose that's all fine, just say so.

Maybe it’s an education thing. If there’s valid engineering reasons like galvanic corrosion but the masses are ignorant of this they may demand a full carbon fork etc which is inferior due to the corrosion, which they don’t appreciate. Which I guess would be a marketing problem. Get the public to want the fork that has glass fibre so that it helps prevent corrosion.

Great work! Interesting that they paid more attention to the seat post portion on the anonymous buy. Maybe it's not a no compromise frame but you got to appreciate the value that it offers. Looking forward to the "on bike" review

If it's safe to ride and rides well, why would it matter? I think it is totally fair for a more budget brand to make more budget focussed material choices. In the end you roughly know the weight of the frame+fork, the penalty of the fiberglass is simply it will be heavier. I rather would have fiberglass in the fork than brake mounts that are not aligned, bearing seats that are too small or too large and everything else that can go wrong in frame production...

Two of the advantages given for a layer of glass are both significant. The dielectric barrier between carbon and metal inserts to prevent galvanic corrosion is huge. The thin glass veil to facilitate visual crack detection, may be less critical.

I far few years ago I had a flagship De Rosa King 3 which had fibreglass in the integrated seat post. A small hole had to be drilled for the clamping mechanism once the seat post was cut to length. My De Rosa Merak which was supposedly a lower spec frame had a similar integrated seat post, but no fibreglass.

Cheap forks use glass instead of quality mandrel layup in carbon, plenty of brands use a glass layer around inserts or as a facing.

There is probably a bit of pressure on the manufacturing side from the middle men to keep the cost down. I thought about an Elves frame but decided to go direct to China and bought a Hyyge model S. Oh and the bit at the beginning when he says the top of the resin is pulled of probably was peel ply removal. A very well respected laminating process... I use it on a regular basis for carbon and glass

Great work!!

Honestly, I kinda prefer the glasfiber being there. Low weight is severely overappreciated in the cycling community and galvanic corrosion is one hell of a bitch, especially when you are dealing with expensive stuff, that you don't want to break. In regards to weight: Yes, the lower the better, but there is a point where the tradeoff in stuff as longevity, usability and aero is just too significant to ignore (unless you are professionally racing and have mechanic or a sponsorship, that makes you not give a shit about durability)

People want high end products for low money, you cannot have the penny and the bun I’m afraid, as long as it looks good and is structurally sound it’s ok to accept cost cutting.

Careful with that type of ultrasonic thickness measurement, it could easily pick up an air bubble and makes it look like de-lamination or thin wall. It uses the first to second interface detected to measure thickness.

Ridley basically buying its framesets from chinese oem manufactures. So yeah, that's why you only found in on Ridley forks.

I bought a carbon fibre bike, a cyclecross, for a stiffer frame as I am big guy; it racks like crazy under load. Afterwards, I found out that for a little more, I could have had a custom titanium frame.

Very interesting Cam 👍

I think this whole issue can be reduced down to three things. 1. When elves make your frame as a cost cutting measure compared to humans, this is a false economy. 2. Completely unverified if Gary's earrings are carbon fiber and he is still walking around. 3. When the stem is flush with the top tube, this can create PTSD and dreadful flashbacks to riding a Look frame with imminent disaster and unfixable complexity. Those are the top 3, but other issues mentioned in the video have relevance as well.

I would really like to see you testing and reviewing Elves Eglath!

Yes, tell us more about the Eglath! The say it is a all-rounder but the geometry seems to be pretty aggressive, even more than in Elves' racy frames.

@@MarianBobolny I have all the Elves. It's an all rounder for sure. But I take the Vanyar for long rides just cuz it's way stiffer and the Falath Pro for city peloton. So I sold the Eglath cuz I haven't used it for a year.

@@MarianBobolny Nobody buys all rounders. They want lightest or aero as if they race every other day.

The more I see about carbon frames, wheels, etc the more it makes me think, I'm sticking with Aluminium or Steel. I'm a big guy and if I don't trust what I'm riding, I ain't riding! Obviously there's the cost factor too! Aluminium bikes are cheaper. It's a win win. I'm old, I don't race, I'm big, I'm not bothered about saving 500 gramms. Thanks for your films. Really interesting. I like that you speak to various people rather than some guy who turns out to be your best mate. 👍

I've got a knew logo for you. The three unwise monkeys. See all evils...tell all evils...hear all evils. Keep having fun! We need it!

I just want to say I really appreciate these videos. You've taught me a lot. Thank You so much. Out of curiosity, I checked 3 carbon steerers I have on hand. A 2013 flagship Merida definitely has unidirectional carbon in there, a Canyon Ultimate from mid 2010s has regular 3k carbon weave and a 2016 Canyon Endurace has something that doesn't really look like carbon, most likely black colored fiberglass.

Carbon corrosion in the same manner as dissimilar metal corrosion is something not talked about often but does take place and should be of concern. Especially in wet environments.

Cam , That review / investigation was so in depth and informative I can only thank you for the work you are doing by enlightening us to new and upcoming brands but also holding them to account as well as the more established brands . If bike brands are watching this then they need to be careful how they describe their products as we as consumers are demanding transparency especially for our hard earned money . Thanks again ,keep out the great content ,I’ll keep watching 👍🏾

This isn't really that in depth. You can actually test the carbon % destructively, something some magazines used to do for skiing sticks etc..

I'm wondering if you're also interested in looking at their other frames, particularly the Eglath, which is marketed as an all-rounder. I wish that frameset got more reviews since it looks amazing, plus the geometry has a less aggressive stack, which would favor more non-race-y people.

I am interested in Eglath as well. The thing is the say it is an all-rounder but actually the geometry seems to be pretty aggressive, even more than their racy bikes. But we must remember that stack and reach do not decide entirely about the bike characteristics, seatpost angle is also important and maybe that makes Eglath more comfortable to drive. In reviews people say it is great to ride!

@@thebespokecyclist3624 Thanks for the info on the Eglath! It just makes me want to get an Eglath even more now (I'm still saving up)

That was a really fasinating video. I have also seen one of a carbon frame being made and you can see why some bits of roughness will always end up inside the frame. The use of glass fibre makes sence now. Thanks for posting this.

I think my view is that i just want clarity from all manufacturers of what theyre doing and why. Im no engineer so im likely never going to fully understand the full ins an outs of why manufacturers use certain materials in certain places, without their clarification. So if they have a good clear reason for (in this example) using fibreglass then be my guest, as long as its not at the expense of my safety or risk of the bike breaking etc. I should definitely say thanks to Cam for this video, im currently looking and possibly purchasing an Elves bike but have been waitijg for the reviews etc, before pulling the trigger. I guess ill wait a little longer.

I don’t bike I don’t know enough about the sport to make an unformed education. It just looks cool so that’s the only reason I’m watching

Sounds like fiberglass is a good option for different areas of the bike, as long as you can bond it effectively to the carbon. I'm not upset about the fiberglass in the same way that I'm not upset my car uses both steel and aluminum. Sometimes you want the properties of one or the other. I don't drink 100% pure alcohol. If you're crazy about the status symbol of the composition instead of the capabilities of the product, you have the wrong hobby.

I'd love to hear what percentage is glass fiber. 1 layer of 5 but only used in a couple key places is different than something using all but the outside layer glass fiber.

Loved this chinese brand elves they make good carbon frames💪🏼

Good luck with transparency. This might be the manufacturer's trade secret to make their forks more resistant to breakage. Lauf fork use fiber glass in their leaf spring which is virtually unbreakable. Fishing rods made of FG can flex to infinity without breaking as compared to carbon graphite counterpart.

Doesn't matter. Even my $450 Ali cheap carbon frames held exceedingly well in tours thru even gravels with nothing loose, cracked, or chipping. Of course you can always pay for a "peace of mind" by paying $5k+ for a frame. Bottomline nobody can prove how much less durable in real life the Elves compared to a Dogma or a $450 frame.

Nice review ... Now can you the same prospection with your BMC ?

- Dude, why you didn't appear on group ride last week? - Steerer of fork got stale so I've stopped riding my bike while new fork arrives.

What comes through my mind immediately regarding corrosion - have you guys ever seen a "big" brand bike frame with fiberglass in the headtube where the bearings sit? Or around the fork crown? Or corrosion of those bearings is not actually an issue only the expander? To me it does not make sense but this is just based on my limited experience. Another thought is that it sounds like some manufacturers are using fiberglass to compensate for poor manufacturing tolerances by machining/reaming these surfaces. I don't think applying a small layer of glass fiber makes much difference in terms of manufacturing costs, it sounds like this is all about being able to compensate for lower quality carbon moulding.

Sorry but with all the various elements to this video I'm struggling to understand the conclusion. Was quality of the new frame good or crap?

There, I learn sth today. Thanks!

The bottom line is you get what you pay for. I bought a frame from Elves and it had noticeable defects. Their answer was doesn't worry it has a warrantee. With these frames you're not going to get good quality control. The upside is they are a fraction of the price of name brands. Are they good enough? That depends on ones price to quality tolerance.

Forget the glass fibre steerer more concerning was the layup variation and if that effects the frame’s strength and integrity.

What a great video Cam. I believe at the end of the day, you get what you pay for. I know for certain that my 2023 BMC teammachine SLR01 carbon fork steerer tube is definately full carbon.

Is there any noticeable difference between a 50/50% carbon and 100% one? Will the 50/50 one be less prone to cracking for example? Or would you need to both ends with fiberglass? The weight doesn't matter though. If you buy a frame you already bought it with the specified weight.

I used to work in an aircraft prototyping shop and we would use fiberglass as an isolation layer when bonding carbon to aluminum, to prevent galvanic corrosion. I wonder if that is what was being done with the steerer?

Man of the people

I've cut into a relatively recent model Yeti mountain bike frame which had fibreglass in the downtube. Certain kinds of fibreglass can have really good impact resistance so it potentially makes sense in an area like that. It does seem a little deceptive to say you have a carbon frame and then sub in some fibreglass. On the flipside I also can totally see consumers not liking it, even if it is a better engineering choice, due to the perception of fibreglass being a "cheap" material.

Gliders (aircraft) are sometimes made of fiberglass, at least the older ones. It's used a lot in general aviation

Glass fibre refers to the fibers, be they in a mat or individual format, fibre glass refers to a complete composite, glass fibers and resin.

Did you measure the thickness of the carbon in the both the "pure carbon" and "carbon + fiberglass" tubes?? Is the fiberglass just there for galvanic protection?

This is going to set the cat amongst the pigeons. The good thing is this may push Elves to change the product, or else, towards transparency. It’s so surprising that no one else has caught this on KZread (independent reviewing my arse)
