Gamux Announces a New Range of 3D-Printed Components

Nov 14, 2019
by GAMUX BIKES  
STEER TUBE SPACER LIGHT


PRESS RELEASE: Gamux

After more than a year of research and development, the moment has finally come. We are proud to introduce our first 3D printed products. Those who have heard of Gamux probably know us because of our activities in the UCI DHI World Cup. In addition to racing, we have always felt the need to put our experience and knowledge into our own products. We used our race team and the extreme conditions of the Downhill World Cup for the development and testing of our products. Out of this process results in a first, small selection of parts, all of which are made using additive manufacturing.

All Gamux products can be found in our online-store and the preorder is now open. Deliveries will take place from November 15th.

We are looking to extend their product line soon. A bunch of components are in advanced testing and have already been raced during the 2019 season.

Garmin Top Cap

Top cap with integrated garmin-holder. Manufactured with additive manufacturing technology, it's not only light & strong but also holds your device in an ergonomic position that is easy to view. Ideal for cross county to enduro riding, for single crown mtb forks with conventional stem configuration


Garmin Top Cap DH

Top cap with integrated Garmin-holder. Like its brother, the Gamux Garmin top cap DH, it is manufactured with additive manufacturing technology. This DH Edition is angled at 15 degrees so that your device fits neatly behind your direct mount stem. Ideal for double crown forks with direct mount stems


Sterrer Tube Spacer Light

The Gamux Steerer Tube Spacer Light is the ultimate lightweight spacer. With only 1.75g (10mm), it's probably the lightest spacer in the world, even lighter than its carbon counterparts. With unique looks, they make your bike an eye catcher


Sterrer Tube Spacer

The Gamux Steerer Tube Spacer combines durability and lightness in a perfect symbiosis. Available in almost every possible size, they enable a super clean looking cockpit setup. The Spacer is an eye catcher and gives something unique to your bike.


Spring Spacer

The Gamux Spring Spacer does not only hold your spring in place. The rumours tell that it even reduces vibrations and quiets down that annoying rattling noise. It lets your suspension work quieter and free from added drag. Furthermore, it does just look gorgeous.


Custom Products

If you wish to have something special and unique, you are now able to join our Gamux Custom Product program. From putting your name on an existing product, up to developing your own special part, we can offer everything to you. Our design and engineering team will advise you on the possibilities. We also offer a “white label service” for B2B customers.


More information about our products and Gamux can be found at: gamuxbikes.com

Cheers and happy shredding!
Your Gamux Team

 Disappointed with the marketing strategy that 3D printed = better product, by default.

As others have said, the point of the technology is to create geometries that you can't achieve via traditional methods, or to speed up product time to market through accelerated prototyping/testing cycles.

3D printing a standard tube section as a mass production strategy doesn't leverage any of the benefits of 3D printing at all.

Worse still, as these products will inherently have microscopic voids and irregularities that could be avoided through traditional manufacturing methods, it could cast a negative light over 3D printing technology as a whole for applications in the MTB industry.

The 3D printed Atherton bikes gusset concept showcases everything that's good about 3D printing. One-off custom components, tailored to the rider, with a complex geometry and multiple functionality that traditionally would have had prohibitively expensive tooling costs. More power to them. Gamux are just playing at it, and feeding off the hype.

 Totally agree here. If we were seeing details that were impossible with traditional molding techniques it would be much more interesting. 3D printing does not automatically mean stronger or better.
  • 10 0
 100% agree!

Additive manufacturing technologies (metal and polymer) are interesting for freedom of design and the fact we don't need specific tools for generate the first part.
If they produce exactly the same components that we already produce easilly by standard processes, it's useless...

As an additive manufacturing (metal) worker, I confirm that we can't reach the same mechanical properties (specifically on fatigue resistance) compared to forged part. Metal AM isn't too bad for bike application as we mainly use 6061 T6 aluminum frames with relatively poor mechanical properties...

 Its f***ing 3d printed! Isn't anyone amazed by anything anymore?
I really have difficult time bitching about anything bike related since i started racing dh in the 90's.
Even shitty stuff now is better than good stuff back then
  • 13 12
 I have to disagree with some of your points. Yes, 3d printing does allow us to create forms that are harder to manufacture via traditional manufacturing methods. Freedom to design and innovate is a big one. However, this isn't the only benefit to additive manufacturing:

1. Less waste vs CNC cutting, forging, injection molding etc. During manufacturing of aerospace parts it isn't uncommon for the ratio of raw material to final part to be 30:1. Sure waste can be recycled but it is one more thing you have to deal with.

2. Speaking to your point about irregularities - Raw materials used in subtractive manufacturing, the condition of molds/ casts and even the process to heat materials for casting can easily be flawed. More processes to make something = more opportunity to screw up. 3D printing is one process that allows the step-by-step assembly of the object, which guarantees enhanced designs and eventually better quality objects.

3. Much lower tooling cost to the manufacturer. This will make it much easier for smaller companies to bring a product to market. This will give us, the consumer, more options to chose from and hopefully more competitive pricing.

4. The workflow timeline for a traditional manufactured part vs a 3d printed part is vastly different. From design through production ready parts on a machined part (includes fixture design, CNC programming, material procurement, QA of fixtures, machine set-up, test runs, optimization of cutting, production runs etc.) can take 1 to 3 months. Additive manufacturing can cut that time down to 2 weeks to a month. It's just easier to get production rolling.

I could go on.

Look, I love traditional manufacturing. I have a mill in my garage and get great joy out of buzzing away at things. But it's like driving a Model T Ford when you could be driving a Tesla. You just can't ignore the fact that additive manufacturing is where it is all headed. Traditional manufacturing methods seem archaic compared to the technology that is available now. All of us craftsmen are doomed!!!

 Sorry, I will add one more thing:

5. Try finding machinist that knows what they are doing or even one that doesn't know what they are doing. It is almost impossible these days. It is a dying art form (sadly). Most vocational schools stopped teaching it and younger generations going into the workforce have no desire to learn. The 70 yr old garage machinist has been a saving grace for small businesses that need parts.

With additive manufacturing you only need a guy that can push buttons.

 They need to google topology optimization for additive manufacturing... Chain guides / bash guards could actually be a cool application for 3d printing.
  • 6 0
 @jptrialsin: You make some good points but I think they are only valid for very very small production runs where the tooling cost would outweigh how many parts you will sell. Maybe that's the case here?

Per point #5 you are absolutely correct but most companies will just send the cad file off to China to have it made for a quarter of the cost of having it made locally. Even with these dumb Tariffs it's still cheaper.

I love additive manufacturing but I'm just struggling to see the benefit of buying these because they are 3D printed. Just looking at the steerer spacer light I would be nervous about it compacting down over time b/c it's 3D printed.
  • 2 0
 @jptrialsin: Yo, I totally agree with your points about waste material, verifying your print layers are structurally sound (as in aerospace 3D printing), reduced tooling cost, time to market etc....

However, don't you think that given the nature of the products being produced here that they would just be better off using traditional techniques? In my opinion, the risks outweigh the benefits on this one. Yes, additive manufacturing is the future for many reasons, but the design of the components needs to match the enhanced capability otherwise you take one step forwards and two steps back.

I hope the company think about innovative components or products they could make which are not possible through any means other than 3D printing. That would be cool Smile

 @dirtdiggler: since when 3d printing us one guy pressing a button? It’s the biggest BS the 3D printing biz is propelling. Printing a 3D object can be more complex than machining it, it has nothing to do with opening a word file and pressing print button. You need to know what the hell you are doing or if you “just send it to China” they may send back something that has little to do with your 3d model. We are printing different kinds of stuff at work on different printers and there’s no way I can model something and press print. I need one of 3 trained colleagues to check my model and help me with it.

I agree with original comment. This here is silly. Like carving a whole frame out of a block of alu.

 @bobsl: A lot of things in the bike industry could be greatly improved with topology optimization. However, licenses to access that can be quite expensive and you need someone with experience using it. I imagine a lot of small bike companies don't have an extra $30k-$150k it can cost for one seat of a capable analysis software.

I agree though, topology optimization really allows you to take advantage of 3d printing capabilities and come up with some really cool designs. I have access to Ansys at work and it's amazing what you can do with it to optimize weight and stiffness.

 @WAKIdesigns: Hi Waki, I was talking about mold making (not 3D printing) locally versus having the mold cut in China where labor is cheaper and the infrastructure for injection molding is more in abundance than the West. Of course! You don't just send off a 3D model to China and get back a golden nugget back! You need to prototype and approve mockups before cutting molds.

 @jptrialsin: 1. Additive manufacturing doesn't create less waste than injection moulding as injection moulding doesn't create waste. All trimmings can go back into the hopper. No complex logistics involved. Depending on the technique, 3D printing of complex parts often requires a support structure that needs to be removed after printing. These can be reused but for that they need to be transported back to the company that makes the filaments.

 Looks cool but I think some evidence of performance would be cool to see here?

What is the 3D printed material? I assume it's some kind of polymer but it doesn't actually say?

How strong is the material in compression, tension, torsion etc compared to aluminium or carbon?

How does the material degrade with time? How do UV light and biocontaminants impact performance? Will bike cleaning products degrade it?
  • 3 0
 It doesn't say anywhere, but I would hope it's sintered aluminum.

 If you download the manual for the items (or at least the top cap: www.gamuxbikes.com/products/gamux-garmin-top-cap) it says it's made of PA 2200 / PA 12, which some googling reveals to be polyamides.

Still doesn't answer the rest of your questions though.
  • 2 1
 @dolface: Theres many Informations on this Type of Material. For example : eos.materialdatacenter.com/eo/material/pdf/399260/PA2200Balance1.0?sLg=en&rnd=1573741604051

Its SLS Laser Sintered for sure.

 Polyamides are basically Nylon . Cheap stuff, but for some applications really good. A spacer? Why not. At least it doesn't corrode.

 @paulcgn: years and years of British winters....and I can't ever say this has been an issue

 @paulcgn: When used under the stem a PA spacer might compress under axial load and allow unwanted movement on the headset assembly. This is relevant to the point of Intend developing their clamp down headset system.

Between stem and the cap you can use whatever you want, but under the stem I'll keep aluminium spacers, thank you
  • 1 0
 @Arierep: Under normal use, these spacers are not supposed to be heavily loaded. You use them to preload the headset, then clamp the stem and after that the stem transfers all loads to the steerer directly. If it would be loaded during use, that would mean that without them the stem could slide down. And if it could slide down without spacers, then it could still twist with spacers. But it doesn't twist (if set up correctly) so it doesn't load these spacers.

That said, the whole attempt at saving weight like this seems pointless to me. Why even bother investing in lightweight spacers. It is the one thing you could transfer from your bike from the year 2000 onto your current bike.

As for nylon, it seems more than up to the job to me. Nylon is tough material, that's what people use it for. Think composite BMX/MTB pedals, housings of powertools etc. Difference here of course that these nylon rings aren't composites (glass filled in the case of the pedals and tools) but just plain nylon instead. Doesn't seem like much of an issue as the glass is there to stop crack growth under tensile loading. As with all plastics though, it is subject to creep. So if it is being subject to continuous loading, it will deform over time.
  • 1 0
 @vinay: sorry, but they are indeed subject to axial loads, and, if the material allows, compress.
When the fork steerer tube flexes the CSU stops being square with the lower headset bearing and as such pushes the steerer down. This also pushes the stem down, which compress the spacers under it.
The Intend Stiffmaster headset exists to address this behaviour.

 The material is Nylon 12, the slightly lighter grey color seems to be a glass bead mix as well. I can almost guarantee this was printed on an HP multi-jet fusion printer. I'm a additive manufacturing tech. btw, I work with parts like this daily. At least we dye most of our stuff! I can tell they really want to push the 3D printed hype with the "raw" look.

 I worked for 4+ years selling commercial 3D printing as a services. I sold this HP 3D printed service many many times. It is a great solution for functional prototypes and some end-use products, but I WOULD NOT RECOMMEND purchasing these end-use components for extreme sports. Also, looking at these pictures it appears these HP 3D printed parts have NOT been fully cleaned which messes with their tolerances specs. I dont know if they are printing them off an HP printer they purchased themselves ($600k+ machine) or if they are ordering them from a service bureau like I used to work for, but either way they need to teach the technician how to clean those parts. Dont purchase sub-quality.

 You can download garmin mounts, chain guides and similar things from the thingyverse and print them for free. I personally wouldn't trust printed parts for mission critical components (yet). 3D printing is great for custom parts or for doing things yourself. If buying from a manufacturer, 3D printed components are less desirable than traditional machining, forging or extruding.

 Wow this is a terrible idea. 3D printing is for prototyping, and building one-off or custom parts that would be impossible to manufacture with traditional methods.

These basic commodity parts are non of those things, and offer a worse value equation for everyone involved, in every possible way. Weaker, softer, hidden defects, time consuming to produce, more expensive, on and on and on.

I wonder how many manufacturers have asked themselves, “How do we replicate these parts that take us seconds to mould or cut, with a process that will take 30minutes a part?” “Maybe then we will be able to capture the market!”

But that’s irrelevant. Gamox is just hoping a few idiots are willing to swallow the hype and shell out for this garbage. As they’ve made no investment in tooling, their sunk costs are very low, it’s all gravy as long as they can find the idiots who want to pay more for les s
