Video: Weird Bikes, Boutique Frames & Dangerholm Builds - Eurobike 2024

Jul 9, 2024
by Jessie-May Morgan  

There was an overwhelming amount of new product to cover at Eurobike. I am overwhelmed. But also, underwhelmed. While there was bit of genuine innovation to speak of, an uncomfortably vast majority of it was old technology, re-worked and re-marketed to keep up a perception that new and shiny things are hitting the market, and if you don't have them, you are missing out. Capitalism, right.

And, maybe, that's just fine. After all, the modern mountain bike is relatively excellent isn't it? And so are the suspension components, drivetrains and other components. I'm waffling, probably because I reached saturation by around lunchtime on day 2 of 5, and only an actual reinvention of the wheel would have sparked a feeling of excitement within me. My senses have been pummeled to the point where exasperation makes up a good 80% of my personality.

However. In this video, we take a look at some of the things that genuinely ignited curiosity within me - as well as some tires that didn't, but you should take a look at them anyway because they do look decent and are probably far more affordable than the tires you're running right now.

Zoceli's boutique steel frames

Martin Saida from the Czech Republic brought his collection of handmade full suspension mountain bikes. To call them gorgeous would be an understatement. This one is the Naosm, his "no compromise enduro machine." That's kind of hard to appreciate given that there's a bottle-opener built into the seat tube assembly and one of the most minimalist brake caliper mounts I've ever seen.

The dual-link suspension design delivers 160mm travel - building it up with a 29" wheelset and a 160mm fork gives it a 64.5° head angle, a 78° effective seat tube angle and a 465mm reach in a size large. Zoceli only sell frames, without the shock. The Naosm goes for 2,990 Euro. Dario has a review of the 135mm Zoceli Narum underway just now.

The Black Math Dropper Frame

You've heard of a dropper seat post, right? But have you heard of a dropper frame? That's what Aleksander Margolis of Black Math Bike has created, and we got to see exactly how it works in person. This bike does not have a dropper seat post, because it doesn't need one. The would-be dropper lever on the bar actuates a hydraulic cartridge allowing the whole front triangle to move in a downward arc, thereby changing all angles of the bike as well as the rear wheel travel.

In the climbing mode, where the frame is in the high position, the bike has 140mm travel. Pushed down into the descending mode, the frame has 170mm travel. It repositions the pivots of the frame's four-bar linkage to alter the leverage curve.

Alutech Pelmo

Of the hundreds of bikes I set eyes on last week, the Alutech Pelmo is the probably the one I'd most like to take for a spin at my local. The Pelmo is a 152mm travel all-mountain bike made in Germany by Alutech's owner and CEO, Jürgen Schlender. It was built up as a mullet with a 150mm travel fork.

The dropout is modular, and can be switched out to change the rear-center length. As seen, it has a 437mm chainstay, but an alternate dropout can lengthen it to 452mm, necessary to accommodate a 29" rear wheel. The Pelmo has a 64°, a 79° effective seat tube angle, and a reach of 490mm in a size large. It fits a full size water bottle and there's frame storage fore of the bottom bracket. That's an unusual place for frame storage, and my feeling is that it'd be quite vulnerable to rock strikes.

Eurobike 2024

That unique finish is credit to Jürgen's willingness to weld each joint not twice but three times before sanding and polishing it off for many, many hours. At a distance, it gives the bike the look of a carbon frame but with a raw aluminum finish. Jurgen will make only 10 Pelmo frames with the sanded finish.

Dangerholm's Scott Scale - Probably the World's Lightest 29er

This is the World's lightest 29er. Probably. Anyone who has made a lighter one, please reveal yourself in the comments. Of course, it's Dangerholm who is responsible for this polished work of art. His Scott Scale weighs a mere 13 pounds, or 5.86 kg. It is astonishingly light. Picking it up gave me momentary vertigo. I do, of course, exaggerate, but it was cool.

Brian has some details on how Dangerholm achieved such a lightweight build in an article here. Gustav Gulholm himself will be revealing the intricacies in due course.

Dangerholm's 3D Printed Cable Integration Solution

Dangerholm was showing more of his recent projects at the Scot Sports booth, where we got the low-down on his 3D printed solution for internal cable routing and cable integration.

 I hate to say it.... while it does have headset routing, that Scott is gorgeous.

 Comments like this almost allowed bike industry to push this sh*t through. Never ever express feelings toward Dangerholm's creations in public. If you like it, like it quietly, cause you never know which beautifull but totally unpractical thing will be the next big thing.

 Would take headset routing over pressfit bb. Change my mind.

 There's little question that cable tourism looks nice. It's simply that most of us here want our bikes to ride well first, and look as cool as they can without excessively hindering the practicality. There isn't much overlap in the Venn diagram of the target market for some bike companies like Scott and the type of rider that wants to comment on PB about this stuff.

 @lkubica: Dangerholm's builds are so far from what manufacturers are pushing stock that it makes no difference. These are complete custom builds with almost every single component modified in weird ways that obviously make the bike harder to work on and less convenient. It looks amazing, and are more works of art than anything, even if they are less serviceable.

I love Dangerholm builds, and it's totally ok to love them and be against stupid ideas like headset cable routing. No manufacturers are looking at his builds and thinking, hey that's what the people want!

 @Hsawaknow46: There are Press Fit BBs out there that (mostly) mitigate PFBB problems and are reliable. Find me headset routing that isn't a total pain in the ass to work on, set up or repair.

 @maxart: kind of an oxymoron as people who complain about headset routing are less likely to buy a frame with cables going thru the headset? I know it's not something I want in a frame! I usually build frame up or buy the lower model and replace the parts and so I'll sure avoid em...

 @Hsawaknow46: Thing about press fit bb. If the hole you are installing it in is actually round and has proper dimensions, it's fine. Companies like Canyon are giving press fit a bad name, as they just can't get their holes round, because their QC process is dogshit

 @tgent: First of all, thanks for all the kind words! This might become a bit long, but I figured I'd share my thoughts a bit about the trend in general and this concept in particular.

So the whole purpose of the design you see here is actually to make the bike easier to work on, while still having that full-on road style super clean front end look. Normally you'd have to go inside the handlebar with the hoses like I've done in the past, which actually to me is a bigger headache than just going through the headset. I'm sure a lot of road bike mechanics would agree that it's not that much fun.

So in theory if this was a production Syncros handlebar, on a MTB with normal routing fork and AXS pods, you'd only have a single brake hose going through the headset, no hose inside the handlebars and very clean looks.
On a gravel style MTB with rigid forks you'd only have two going through the headset, as you can go inside the fork in this case too for the front brake.

So while there of course will be people who feel like this is not for them, the point is that what makes headset routing "worth it" is clean looks and here you get it with minimal hassle.

And this ties into what I believe is the "problem" with headset routing, that it was introduced a bit too soon and a bit too widely. With the big talking point being clean looks, the component manufacturers hadn't/haven't stepped it up with for example brake levers with better hose angle and entry point (current Shimano brakes can be an example here). Also it should perhaps just have been introduced on the high-end bikes with AXS, keeping the number of cables to a minimum.

Because if you imagine a future were you'll have the style shown here on fully electronic bikes, for us who values clean modern looks, and traditional setups for the "purists" or more entry level bikes - things would be pretty damn good if you ask me!

Btw, I'm incredibly thankful for Syncros putting their R&D department on this project and for Trumpf (who produces the actual printing machines) supporting it with their expertise. This handlebar literally started as a carved wood concept prototype in my workshop some 18 months back, and here we are with a fully tested and rideable prototype. Nerd dream come true.

 @Hsawaknow46: Press fit BB works fine when made to correct tolerances. I've owned 9 that have been creak free.

 @dangerholm: Excellent explanation, and I totally agree that once you go full wireless, 1 brake cable going through the headset really isn't a big deal. Also on custom builds by a clearly very good mechanic, it again isn't a big deal as you'll never be dropping off this bike to the bike shop begging for them to do a quick service job on the weekend. You the man!

 @Fix-the-Spade: 100% - Press fit issues are because of faulty execution not bad design. If tolerances are tight, PF works fine, and has potential advantages, such as weight and larger bearings.

 @dangerholm:
I'm actually pretty fine with the headset routing. I've got a spark with all the cables and it's still easier to work on than my other bikes.
My problem (and maybe suggestion for next prototype/concept design) is the lack of adjustability of the integrated cockpit or even the semi-integrated stem on the lower end sparks. If manufacturers want to keep pushing integration, let's see some progress on making that adjustable too! I think canyon is trying this in their road bikes.

Nice work on the clip instead of zip ties or clamps by the way. I don't know why that isn't the standard for all cable retention designs.
  • 2 0
 @headset-apologist: Ok, I'll bite. How is it possible that your Spark is "easier to work on" than other bikes? Unless you previously only owned some real stinkers of design, that seems impossible. Want to do literally anything to the shock? Added steps in taking off/on the cover. Need to change a cable? Dropping the fork as well.

I don't think the whole headset cable routing is as big of an issue as it's made out to be, but it certainly isn't a step in the easier direction compared to almost any other bike. Especially modern bikes that have tube in tube cable routing, pushing a cable/hose into the frame and having it pop out the other side is quite easy.

 Bike companies are actively coming up with reasons NOT to upgrade like the no cable derailleur option for the stumpy 15...

 @stiingya: I finally made the plunge to AXS GX, came stock on my Stumpy Evo. Now when I ride my older rig with regular stuff, really drives home how great AXS is. But yes, technically can't mash quick through multiple gears in either direction. If that's your thing, then definitely stick to cables until they figure that out.

 @Chuckolicious: It's not whether "it's my thing" it's removing the choice for very little gain in frame design. I don't have the desire to need to charge a derailleur battery. It's not something that creates a "significantly" better user experience IMO. If you can't live without it now that's all good. But I think it was a dumb decision to take away the choice...

  • 10 2
 @stiingya: Funny thing is that when it comes to the derailleur there actually isn't much of a "why" behind it except for making it look cool.

The project was a way for Faction Bike Studio to dive further into the 3D printing world while also showcasing their design and engineering capabilities - and for me to get a really cool looking rear derailleur. The original plan was to also have the b-knuckle (the big rearmost part of it) printed to make it look even wilder, but time was limited.

This derailleur is actually going on one of my upcoming gravel builds, where the cage design isn't a problem, with the red Spark featured here got a Transmission setup installed just yesterday. But as this bike is full of 3D printed and prototype parts (aside from the handlebar, the brake levers and bottle cage are also printed in titanium) so I took the chance to show this setup while at Eurobike.

 Dropper frame needs a dropper post. Seriously though, pretty cool idea. Canyon Shapeshifter evolved.

Bring back travel adjust forks. 170mm frame that could drop travel to 140mm (fork too) and still be ridden as an aggressive trail bike (or "slopeduro" for tighter jump lines) would be pretty sweet.

 If you don't have those really really steep and long climbs, this gearing range makes a lot of sense for fast paced and flatter XC/marathon style riding. So depending on where you live and ride, it can be a good option to the 10-52.

 Re; 3d printed things like stems....how strong is it compared to forging, welding or machining?
  • 4 0
 Not a great production material for things like stems. If you do it right it can be close-ISH to a CNCed stem, but it's excellent for prototyping. I feel like Syncros could do a carbon version with a channel to then clip an injection-molded section in to route hoses.

 @brianpark: imagine putting that many resources into creating a bar / stem that provides zero benefit to the rider other than questionable aesthetics while removing all the benefits of a conventional bar and stem.
  • 7 1
 Like Brian says, there are limits but the key is to use it right. I think a common misconception is that 3d printing is supposed to be lighter, but in reality the two best ways to use it on a bike is prototyping or to actually make parts that wouldn't be possible or difficult with traditional manufacturing.
We're still at that point where we see a lot of 3d printed "versions" of things just for the heck of being 3d printed (which also is super cool, don't get me wrong) but the true potential to me is when you can do a completely new design idea thanks to the new possibilities this production technique brings.

Would be surprised if this stem / bar got close to surviving IS lab fatigue testing, but it doesn’t need to.

 Is that whole Dangerholm integrated stem and bar 3D printed!?
  • 4 0
 Almost! Like Jessie-May says in the video, the whole silver center section is one piece of printed aluminum and then the tube sections at the ends (where the grips/brakes are) are carbon tubes that have been bonded into the the aluminium.

The handlebar is actually quite overbuilt, and fully tested, so it's 100% safe and good for me to go ride.

 @dangerholm: by ‘fully tested’ - it’s survived lab fatigue testing at EFBE or similar?

If so, that’s super impressive and interesting to see how far aluminium 3d printing has come.

 @justanotherusername: Yes exactly, a key goal with the project from the very start was to make it fully rideable so that I actually could use the bike. So they made more than one, with a couple of them being sent off for testing and it passed with no issues.
