You should first make a prototype maybe out of wood. If you go that far making the carbon fiber version isn't much more involved. It's basically cutting and gluing. The most important and expensive step when making custom things is the blue print and research and and development focus on that and the rest is easy. That's why the Chinese brands are taking over they skipped the hardest most expensive part
That triangle of Light/Cheap/Strong still exists - for the masses. You broke it , because you had the combination of skill/knowledge/time/dedication. Kudos! + this is one *sick* video !
This sparked the thought---"Would aluminum tent poles work?" They're cheaper, lighter weight, come in tons of colors, are reasonably rigid, would be easier to work with, and there are some stock fittings that could be repurposed for something like this.
Really appreciate how well you conveyed all the important points in a fun 2min video. Thanks for taking the time to edit that. I don't always have time for the 20+ min versions of this most tinkerers would start with.

Just want to say thanks for this video. I followed your instructions and made a similar rack for my folding bike. Ended up not needing to drill the eye-bolts.

Nicely build, i would guess the bolt connection Points are the weakest spot. After finding the right angles you could wrap around the spots with rovings.
I think the weak point is the tensile strength of the epoxy at the change in material. They will be fine under compression, but I'm concerned they may pull out after a few 1000k of vibration.

I'm all over this, i was going to do a similar job will some Ali rod but this carbon is next level. I might try one in bamboo, nothing fancy, just from the garden centre.
@@SladeTakalaLamey Just a thought too, if you struggle to get the ID correct, you could fill a bigger ID with something like epoxy, then drill it out to whatever specification you need.
Great intro and videography - a real shootdown of Keith Bontrager's Maxim [light/cheap/strong etc]. I think I'll try building one as well. Sidenote: - cutting carbon fibre is a potentially hazardous pastime. As one who is missing a bit of lung from asbestos related disease, attributed to too much time spent decades ago in an Air Force cockpit, take plenty of precautions. I love your bags! My old and somewhat sketchy aerodynamic theory comes to mind: For the rear, you'd need an inordinately long bag shaped to reattach laminar airflow, or Kamm tail to create a turbulent 'bubble'. For a front mounted bag, it is of course feasible. I'd steer away [pun intended] handlebar bags as both the centre of gravity and centre of aerodynamic pressure[s] would be well forward creating handling difficulties - especially in a crosswind.
Greeting from Slovakia. Man, you are a legend. Now I am looking for a way, how to adapt your build for my road bike. I am probably gonna use thru-axle for Topeak bike trailer, as I don't have braze-on rack mount on my bike. Thank you for the video!
Would be absolutely awesome if anyone could document it in written text ... Maybe a reddit post or something? I am absolutely interested in this. The idea of using the topeak axle sounds awesome PS. I also recently got a Waltly gravel :)
I'm interested in the bag and the aerobar setup in the front.

What did you put inside horizontal/inner/middle tubes? About 1:00 Whats the purpose of it? For me it looks like some metal rod/stick so there is more gluing/connection surface for epoxy?
i prefer the tailfin but honestly this is a perfectly good and nice solution too, well made :) love that you even anodized the bolts on the gas stove haha. note: might want to indicate that the quality and type of epoxy matters immensely for these things. now .. wheres that subscribe button.. ah.. found it. Inspires me to make a panier rack like this too.. it is stronger and lighter than what you can buy indeed and not all that difficult to make.
Brilliant! Some of that would require me extending my skill set. I think I could pull it off though. That is, unless you're taking orders. I want one for *my* Waltly....which will have bolt holes on the seat stays.
@@SladeTakalaLameyI'd buy one. I have an idea for spacers at the seatpost clamp that would allow the horizontal rails to be parallel. This way, non-custom bags would be compatible. I'm also thinking about a mount for taillight/radar on the rear element.
@@michaelnewman4302 currently I do all my adventure riding in Finnish summer time, lights never even crossed my mind. I'm taking it on the Midnight Sun Gravel this year, where the sun barely goes down.
@@SladeTakalaLamey That's understandable. Here, most of my riding requires a taillight. A rack that light I'd probably leave on the bike all of the time. As I progress with a design based on yours I may settle on something as simple as epoxying a Garmin mount on the rear member.
It's in the plan. This very morning I've been looking into how to take readings from a multimeter via a USB, so I can see how much power I'm drawing. It's a whole lot cheaper than a Garmin Solar though.
Hi! It looks great. I have few questions. Can anyone help me with them. - why use glue for middle rods - what is the correct way to test the strength of such structures. Putting load on it is not sufficient. In real like situations, force on it will be lot more due to jerks and acceleration - carbon rod vs carbon sheet molded? Ik most likely no one will answer these questions. In case anyone does, thanks in advance.
Hi, I'm doing my best to answer all the questions, I'm still a small enough TH-camr for that. The middle rods are only there to stiffen up the lateral flex and also to provide a platform for bags to sit on, so they didn't need to be that strong. I plan to test the tensile strength test of the rod-nut-bolt combo by stringing up the eyelet in each end and seeing how much weight the epoxy can hold. I have some leftovers to play with. Thus far I have pulled as hard as I can with a string loop at each end, and they didn't budge. I'd love to see a carbon-sheet rack, but that is for someone else to tackle! Please send me a link if you see one. I'm testing it out in a 1000k gravel race in a few weeks, so watch this space and I'll let you know how it holds up.
Casco, strong epoxy professional. It's the basic supermarket stuff. I hope it holds, I'm keeping it on my bike all summer long, so I'll keep you posted.
Amazing ! I didn't understand what you are doing from 0.40 to 0.45 in the video. You heat the bolts before enlarging the hole, then youput them in pot of water ? I just ordered everything, can't wait to try to create my own tailfin 😝
Amazing, I'd love to see how it turns out. Yes, I heated the bolts to soften the metal (otherwise I would have got through a few drill bits). Then I heated them up again and rapidly cooled them, thus hardening the metal again. I'm not a metal expert, but I think that's how it works.
@@charkes1936 Hi, there are no stupid questions. Stupid people don't ask questions and remain stupid for ever. The M6 eye bolts have M5 holes (these work really well for the standard M5 mounting holes on the bike). That meant that the Flat Head Blind Rivet Nut had to be M6. Which in turn meant that the tube was 9mmID and 11mmOD. That meant the gold coloured bolts that fit into the ends of the cross brace had to be M6. So the Eye bolts didn't fit. There may be an M6 eye bolt with an M6 hole but i couldn't find one. Hope that helps.😀
Very nice! So is it stiff enough while riding? What kind of carbon tubes and which glue did you use? I built a lightweight aluminum rack for my race bike which has no rack mounts. It hold for three days bikepacking. Then it broke at home because the bike fell over 😂 my second approach was to buy a common bike rack and only build some sturdy adapters from aluminum. Works great but looks meh.
So far it's really stiff. I'm only carrying my hammock and sleeping bag stuff in it so it's doing really well. I'm gonna try not to drop it. 😁 The tubes are linked in the description, they are 3K 11mmOD 9mmID, the epoxy was Casco blue.
Will it handle loosely balanced panniers of 12 kilos each on mildly rough terrain? Meaning, say, gravel roads or cobblestone stretches of 1-5 kilometers (with turns)
I'll let you know after the summer. Only used it for this film so far. I'm off on the Midnight Sun Gravel 1000k in a few weeks, so keep a watchful eye and I'll let you know.
I used 80mm and 25mm, although the 25 could have been longer if I'm honest. I'd do 30mm. But is you wait for the detailed video which is coming out soon, all will become clear.
Your tubus is worth the cost and the grams because it tested and won't break under load nor because of being slightly bumped. Carbon DIY jobs like this are cool but impractical to use because you're never going to be sure how well it holds up unless you're an engineer and have a lab to test its strength/fatigue.
@@Primifluous it is reassuring to know it's going to work as intended as long as I stay within the weight limit. The DIY rack still has it's value for lightweight bikepacking, just need to conduct visual inspection periodically to check for cracks. Maybe even build one that can be disassembled and packed as spare or when not in use since it's so light.
I'm rather hoping someone will let us all know. There have been lots of people saying they will give it a go, and I'm encouraging everyone to send me pics when they have completed. Watch this space....
I know it's a cheeky jab at tailfin, but there is no way your rack holds up those 40lbs on a rough decent for years of use. There is a massive difference between static load and dynamic load. Awesome design though! Sid eto side loads might be an issue, I would ad cross members from the down truss to the opposite horizontal truss to stiffen it.
It's working a treat for my bag with my sleeping gear in it and that's all it needs to do. No need to over engineer. But I agree, if I needed it to do more, it would need better support!
i bought a german made premium product and its just fine though. As someone who works in manufacturing diy is more or less my last option because i dont live in the lie that diy is cheaper or better for what i can realistically do.
Mmm, that's going to last a LONG time. The last thing you want on a tour is a snapped rack, particularly for the sake of saving a few grams. Tubus you ain't.
I’d love to see a more detailed instructional video on how to do this.
I have lots of bike race promo films to make in the next few months, but if this one goes well, maybe I'll revisit it, slow it down and add commentary.

The M6 eye bolts have M5 holes (these work really well for the standard M5 mounting holes on the bike).
That meant that the Flat Head Blind Rivet Nut had to be M6. Which in turn meant that the tube was 9mmID and 11mmOD.
That meant the gold coloured bolts that fit into the ends of the cross brace had to be M6. So the Eye bolts didn't fit.
There may be an M6 eye bolt with an M6 hole but i couldn't find one.
Hope that helps.😀
Very nice! So is it stiff enough while riding? What kind of carbon tubes and which glue did you use? I built a lightweight aluminum rack for my race bike which has no rack mounts. It hold for three days bikepacking. Then it broke at home because the bike fell over 😂 my second approach was to buy a common bike rack and only build some sturdy adapters from aluminum. Works great but looks meh.
So far it's really stiff. I'm only carrying my hammock and sleeping bag stuff in it so it's doing really well. I'm gonna try not to drop it. 😁
The tubes are linked in the description, they are 3K 11mmOD 9mmID, the epoxy was Casco blue.
Will it handle loosely balanced panniers of 12 kilos each on mildly rough terrain? Meaning, say, gravel roads or cobblestone stretches of 1-5 kilometers (with turns)
I'll let you know after the summer. Only used it for this film so far. I'm off on the Midnight Sun Gravel 1000k in a few weeks, so keep a watchful eye and I'll let you know.
This is great! 200 grams ligther than my tubus airy titanium and wayy cheaper. Liked&subscribed! What's the length of the ring bolt needed?
I used 80mm and 25mm, although the 25 could have been longer if I'm honest. I'd do 30mm. But is you wait for the detailed video which is coming out soon, all will become clear.
Your tubus is worth the cost and the grams because it tested and won't break under load nor because of being slightly bumped. Carbon DIY jobs like this are cool but impractical to use because you're never going to be sure how well it holds up unless you're an engineer and have a lab to test its strength/fatigue.
@@Primifluous it is reassuring to know it's going to work as intended as long as I stay within the weight limit. The DIY rack still has it's value for lightweight bikepacking, just need to conduct visual inspection periodically to check for cracks. Maybe even build one that can be disassembled and packed as spare or when not in use since it's so light.
Impressive!
Thanks very much!
How's it work with panier bags?
I'm rather hoping someone will let us all know. There have been lots of people saying they will give it a go, and I'm encouraging everyone to send me pics when they have completed. Watch this space....
Amazing!!!
💥Fantastic 💥
Brilliant, and thanks for posting component parts source.
They're affiliate links, so no it wasn't pure altruism. 😁 But you are welcome!
Yup, that gets a sub and like.
Impressive
I know it's a cheeky jab at tailfin, but there is no way your rack holds up those 40lbs on a rough decent for years of use. There is a massive difference between static load and dynamic load.
Awesome design though! Sid eto side loads might be an issue, I would ad cross members from the down truss to the opposite horizontal truss to stiffen it.
It's working a treat for my bag with my sleeping gear in it and that's all it needs to do. No need to over engineer. But I agree, if I needed it to do more, it would need better support!
I'm subscribed
i bought a german made premium product and its just fine though. As someone who works in manufacturing diy is more or less my last option because i dont live in the lie that diy is cheaper or better for what i can realistically do.
@@TommiHonkonen 2 out of 3 ain't bad for some. DIY is always more interesting tho.
I think you just started a business. When can I buy one?
If you want to go even cheaper I bet you could do something similar with bamboo
Subbed, great content
!
Thanks very much
Please can you tell me song name?
On a ragga tip!
@@SladeTakalaLamey thank you👍
@@SmailAziko Pleasure. It's a millennial classic.
@@SladeTakalaLamey Yes, thank you, it’s surprising that I have never encountered this music before. Thank you.
Awesome tutorial and idea! Just don't go over 10kg it won't hold more if you ride.
I'm a bike-packer much more than a tourer, so it does me good!
Nice but.... static weight vs dynamic weight. Probably have more real world potential with a second pair of struts from the seat stays :)
I've tested it with a bag full of camera batteries and jackets, I'm off on a 1000k packing race in a few weeks, so a long-term review will be coming.
👍👍👍👍
be great if you could make a video about it...[edit, nah I had another look and I can just about suss it out, cheers!]
Just in case: th-cam.com/video/sLK4O2Unjhk/w-d-xo.htmlsi=uYzmTscVNEvruUrh
killa 👍👍👍🤙
do you take orders?
Not yet, but if I get enough requests, I plan to launch it as a buyable kit.
😎👍
subed awaiting update video 👍
Bad ass!
Nice, but if i paid myself for the time that would take me much longer than $500 in labor cost.
the algorithm like this video
She's a cruel mistress and I've been on the wrong side of her for years, so it's really nice that I'm finally getting in her good books.
@@SladeTakalaLamey Yeah, definitely deserved. What about the bags? How did u made them?
That film is coming soon, But first the solar panel film - out v soon.
thats bad ass
Basically I need a few carbon sticks and somebody who can connect them in the right way.
Yup!
noice
Mmm, that's going to last a LONG time. The last thing you want on a tour is a snapped rack, particularly for the sake of saving a few grams. Tubus you ain't.
I'll let you know if and when it does. Thankfully the bag can double up as an arse rocket.
