Video: Gamux Launches Runi Gearbox Enduro Bike and Marca Downhill Bike

Sep 10, 2020
by GAMUX BIKES  

Press Release: Gamux

After more than two years of development time, Gamux is proud to finally present the Runi and the Marca platforms to the public. Enjoy our launch video where you are presented with all the information regarding our two new bikes and our company/brand.

If you just wish to jump to the bike-details directly, please use the timestamps in the video timeline to jump between different chapters.

Also, you can find everything in written form below the video.

The Runi


The Runi is made from high quality 7005 aluminium. We chose this material because our manufacturing partner MiTech has many years of experience in working it and knows the pros and cons of working with it. The properties and characteristics are amongst the very best for frame construction and allow us to implement custom geometry (OGO) and drivetrain options (MDO). OGO and MDO let you choose reach, stack, headtube angle, seattube angle, chainstay length, BB height and drivetrain style. We are more than happy to guide you through the process of choosing the geometry and making sure that it fits your wishes the best way possible. In case you wish to enjoy a bit more simplified process, we can always create a suggestion for you based on your wishes and inputs.

RUNI pre-production frame
You can choose between a traditional press-fit BB and a Pinion P- or C-Line gearbox.

Besides custom geo and drivetrain options, the Runi features our VKP 4-bar suspension platform. VKP enables us to provide customizable suspension kinematics, so you can choose your desired rear wheel travel and leverage curve to best suit your style of riding. Combined with specifically tuned Öhlins shocks, VKP will provide a suspension behaviour that is confidence inspiring and best suited to your riding.

RUNI pre-production frame
Specific link-configurations allow for individual travel and leverage options for our customers.

The dropouts and suspension linkages are printed in AlSi10Mg aluminium by the additive manufacturing experts at TrovusTech in Germany. Manufacturing key components with additive manufacturing technology (AMT) allows for enormous flexibility when it comes to customization and creating one-off parts for customers. Also if your riding has evolved or you wish the bike to feel different, we can always make alterations to those components to provide you with the feeling you wish by changing out the AMT-components.

The Marca

MARCA pre-production frame

The Marca wants only one thing: making you go faster down that racetrack. Its development has been heavily influenced by our team riders and the needs of UCI World Cup DH racing. We made thousands of data runs to check the correlation between time, feeling and the data. It is about creating a base platform that embodies what we think is the fastest configuration down the hill. It is our way to bring WC factory level equipment and customization to you.

MARCA pre-production frame
The specifically tuned TTX22m shock makes the roughest tracks feel smooth

Our OGO technology is also featured on the Marca and lets you choose reach, stack, headtube angle, chainstay length and BB height. It is also able to be configured for a full 29er or a mullet setup. We are happy to help you with our World Cup experience, making the specification of your Marca an enjoyable process. We can even provide you with full geometry suggestions based on the inputs you give us.

MARCA pre-production frame
Custom dropouts and linkages allow for quick adaptation to different track characteristics and terrain

Key components of the Marca such as linkages and dropouts are made with AMT. This enables us to provide multiple options for kinematics and geometry depending on the track and terrain. You could have multiple different dropouts, making the bike either more stable or better cornering. The same goes for the linkages, enabling slight geo changes such as lowering the BB and slackening the headtube angle if the going gets rough and steep.

The Marca in detail:
- AL-7005 hand-welded frame
- AlSi10Mg 3D-Printed components made by TROVUSTech
- DH-Link suspension system by Federico Biora

The Technology

Varius dropout prototypes. 3D printed by TROVUSTech

AMT | Additiv Manufacturing Technology
For GAMUX, AMT is the strategic technology that will disrupt the industry long-term! We think that the 3D-printing ecosystem can revolutionize the design and manufacturing of mountain bikes. Therefore we are supper happy to have partnered with AMT experts TROVUSTech. Together with their knowledge, we can push the power of AMT to the max.

VKP | Variable Kinematics Platform
Thanks to AMT, we can provide fully custom kinematics to our customers. VKP is our way to tune and modify the character of the kinematics to best suit you. Further we can configure the custom tuned Öhlins shock to exactly match the kinematics of your bike and your riding style.

OGO | One Geometry Only
OGO is our approach to custom geometry. We provide our customers with the geometry that fits to their biometrics and riding style. GAMUX will only provide you with one size of bike: The one that fits you the best. Thanks to the longstanding experience of our frame manufacturing partner MITECH, we can provide high quality, handmade frames in produced in Europe.

MDO | Multiple Drivetrain Option
MDO is our approach to spec the best possible drivetrain options without interfering the kinematics or the overall aesthetics of the frame. Our bikes are designed to accommodate multiple drivetrain options while maintaining all the other characteristics. It is up to you to choose between a conventional 1x12 drivetrain or a Pinion gearbox.

 The number of acronyms in this article made me feel like I was having a stroke

 They were so busy using their time thinking up all these acronyms that they forgot to put a bottle cage on the frame.
  • 10 2
 Four acronyms, that's still well below industry standard, isn't it? Either way, I think this is really cool stuff. Obviously as there is so much flexibility, this product is only for the rider who really knows what he/she wants and can't find it in the current bikes on offer. So it is inherently niche. But it is cool that there are brands catering for this niche. I'd say this might be a competitor to Nicolai, which are some huge shoes to fill!

 I wish there was at least some base geometry provided to have a sense what I see on the pictures. Anyway interesting approach (like Atherton bikes) to go with full customization. Curious how that affect price and if by the end of the day is really worth it.

 Hey Kusa,

The Geometry is custom to each customer, so there are no "strandard" geo-numbers. But if you are interested, you can contact us via our webpage and we can give you a geo-recommondation based on your requirements.

 Every time i read an article discussing "kinematics" i cringe. kinematics is the study of movement WITHOUT relation to force. Far too much stock is put into it. There is setup window for anti squat. everyone is there or there about. Its nothing more than marketing BS to sell more bikes to mindless consumers.
In the world of motorsport, things have moved on, anti squat/dive and roll centres and roll axis is calculated in force based equations. Its more accurate and more relevant study. And when I say moved on - it happened 25 years ago.

 Yikes that video! I was def not the target audience. Why can't the belts have linkage? I like the gearbox concept and a belt (always hope they get better) but keep the long lasting RT in one piece and have a link on the belt.

 Pay for what ypu like, blame all on you!

As much as everyone would like to be, this kind of products are in reallity WIP (Work In Progree), because nothing is really developed, due to so many variations.

I supose the bike industry takes several interactions to arrive to ONE solution!

And on this type of products, you pay to have YOUR interaction, with no further tweak.

Personally I don't care about this. Sure is nice to have all the options, bla...bla... but in reality I can live with simple basic features (like 3 to 4 frame sizes, only rebound adjustment) and focus on the ride and technic.
Of course around here we only have PROs, and we all know that PROs need adjustment to achieve those KOMs....

 @GAMUXBIKES: thanks!!

 @Zany2410: The real question is re these pinion gearboxes (well 2 questions) a) Have they changed these so you can you shift under load? b) Is there a handlebar trigger shifter yet?
  • 4 0
 @CDT77: it is a gearbox. gearbox can not shift under load. do you even know how a gearbox works?
  • 1 1
 @embi: FFS buddy.. relax... my point is -> until they modify this to be able to shift at least as well as your standard cassette type its a non-starter for a trail bike for most ppl. Pinkbike pointed this out in a test they did a while ago stating this exact fact...
  • 1 0
 @CDT77: shifiting under full load - no, shifting under little load - yes, practicing to shift while in the deadspot - doable

trigger shifter are available for pinion and rohloff

 The welds are horrific. Look at the close up of the shock and linkage. You can see repeated craters (the little dimples in the middle of the weld beads), which will _absolutely_ lead to cracking in the long term.
Would love a gearbox bike, but they need to work on QA.

 @neimbc: Maybe, but even so, why showcase a raw frame with known defects, while promoting your manufacturing partner?
  • 12 1
 While I agree; not the prettiest welds, but those are not "craters" and will probably not ever lead to cracking. Are you a welder?
  • 17 0
 Hey enki,
Thanks for your input. This is still a protoype / pre-production frame and was welded under a bit of time pressure to make it to the launch today. Rest assured that the welding quality will be imaculate for the production bikes. This is also why we have opend the preorder now to ensure we are not under unnessesary pressure when it comes to the quality of the frames
  • 7 1
 Not so sure I'd call them "horrific".. Admittedly I'm only a hobbyist welder, specifically on a TIG, but they don't look that bad. Granted you might have been able to zoom in better and saw something I missed.
  • 7 0
 Doesn't 7005 aluminium produce far more volumous welds that a lighter alloy like typical 6061? Keyboard welders will slate brands nicolai and commencal for their sloppynes 'horrific' quality without having any experience in frame composition or welding in the first place.
  • 2 0
 @felimocl: nicolai frames have massive welds because of technique they use(very slow pass in "circles"), not because with alloy used it has to look that way.
  • 1 1
 That's why they choose 7005 alu min ee um...because you can get away with shit welds.
  • 5 0
 7005 is a stronger alloy by being more stress and fatigue resistant without a weight penalty. If a bicycle brand wanted to use a a material to get away with shit welds then they'd use shit steel.
  • 2 0
 @felimocl: yea that's true...ok I take the comment back.
  • 1 0
 @felimocl: the difference in density between 7005 and 6061 is 0.08g/cm3. and its 7005 that is lighter. A rushed job leading to this poor quality of welds would only be a defence if the deadline was hours. This will not be the first two frames theyve built, just the first two we are seeing. I can't wait to hear how many thousands of euros this uninspiring frame costs.

 We need a DH bike with a gearbox! The two gearbox bikes I've ridden both had the best suspension platform I've ever felt, but the drag was a bit of a bummer. But on a DH bike, I don't think it'd be an issue. GEARBOXES FOR DH BIKES. Also a clutch on a handlebar remote that would basically disconnect the drivetrain while coasting would be real neat.

 @kfccoleslaw: exactly! I would think the drag component of a gearbox drivetrain would make it less advantageous for pedaling endeavours

 @mentalhead: Hey, thanks for the question.
The only reason is that our data has clearly shown that even smaller people are faster with a mulltet than wit a 27/27 setup. so that is why we did not bother to make a 27/27 inch version since the Marca is developed for sppeed.
