Bike Check: The Zoceli Dobordelu is a Steel Bike with a Sliding Shock

Aug 18, 2021
by James Smurthwaite  


A lot of smaller brands that deal exclusively in steel bikes like to keep things simple. The ethos goes hand-in-hand with the toil of long hours in the workshops jigging and welding a frame from a material that most of the industry left behind years ago. Martin Saida, of Zoceli Bikes, is one of those small-batch builders, but rather than revert to a standard single pivot he instead decided to challenge himself with something a bit more intricate. Martin has been a mechanical engineer for seven years and, inspired by the classic Yeti 303 downhill bike, decided to create a steel full suspension bike with a sliding shock. The result is the stunning Dobordelu prototype.
Zoceli Dobordelu Details

Frame Material: Columbus steel
Intended Use: Enduro/ Freeride
Travel: 180mm
Head Tube Angle: 64°
Seat Tube Angle: 78°
Price: N/A

At the heart of the bike is a single pivot that isn't quite as high as the Yeti it is inspired by, but still sits comfortably above the chainring. Instead of having the shock connect the front and rear triangle, as you might expect on a single pivot, the shock is mounted onto a carriage that slides along a rail built into the downtube. The carriage is guided by two machined aluminum arms and the whole system allows Martin to tune the suspension more precisely than a standard single pivot.


Crucially, the slider design makes the Dobordelu more progressive with the leverage ratio on this frame changing from 3.25 to 2.45 as the bike moves through its travel. The design also keeps the centre of gravity of the bike low and, let's face it, looks damn cool too.

Of course, there are a number of obvious drawbacks including the fact that there's a large moving mass, more friction in the system, ingress of mud and dust and, Martin says, it's pricey. It's because of this Martin doesn't plan to ever bring this design to market - he views it as an engineering puzzle he was happy to solve.


Zoceli hails from the Czech Republic and the name translates simply as 'Steel'.

Martin never got round to painting the prototype in case it needed some changes so it started picking up some rust. He liked the effect so much he allowed it to cover the whole frame.

Machined aluminum is used to complete the unique design.

Cable routing for a dropper is integrated into the seat tube.

Martin built the rest of the bike as a freeride/enduro monster truck with 180mm travel front and rear and 29" wheels. It has equally rowdy geometry to match, with a head angle of 64°, a seat tube angle of 78° and a reach of 455mm on this prototype. Martin spent nine months in total working on the bike and has had the chance to get in a few early ride impressions. He said, "It behaves similarly to a downhill bike, but with the advantages of an enduro bike. The frame sails the trails without hesitation, it is exactly what it was created for. The sensitive system keeps the wheels on the ground and ensures great traction."


Unfortunately, the Dobordelu will never see a production run and it will instead be Martin's one-of-a-kind personal bike. He has learned a lot from the process though and will be using those findings to improve his other frame, the Naosm. For more information on that frame and how to order one, visit Zoceli's website, here.

 @ThreadedBB1day: came here to say this… the effect is cool at first but section-loss at critical tubing junctures is death. Break the whole bike down bare, be sure to scrub surface-rust off with a Brillo or coarse steel wool, and treat everything (like a complete dip, or at least spray inside the head-tube junctions) with a rust-killer / converter before clear-coat. Do a matte-clear powder-coat for best result. Will still look amazing.

  • 21 0
 In the industrial world these are known as linear rails. The slider blocks can be ordered with full sealing and special lubrication pockets. They are meant to be used on machining centers and other systems which need linear motion. They work very well and are actually quite low friction and are standard parts available online anywhere in the world. They are of course more expensive than a couple radial ball bearings but can contribute to the rigidity of the system unlike a radial ball bearing as the blocks can come with oversized balls to a specified preload amount.

 @naturaltalent: Wondering how easy to clean and reliable Trek’s IsoStrut-damper on their Supercaliber bike is then.

Seems like a similar issue - anyone has any experience with it long term?

  • 2 0
 @whiteboarder: I had a supercaliber for about a year and a half, and I have serviced the isostrut once, it functions the exact same as it did day one, but also its not a ton of travel so its hard to compare to this because there's not a lot of tuning to get your suspension "feeling good" when the point is to take the edge off the big hits and keep the bike climbing like a hardtail. In terms of reliability I think its good but you know you need new seals and dust wipers when you start hearing the squeak of dry seals on that stanchion, as for getting dirt and grime in the linear slide I have never had a problem, I wash it after every ride and even on the muddy days its the cleanest part of the bike but I would attribute this to the slide being under the top tube and not right next to the bottom bracket. these were some unorganized thoughts but I hope I answered your question.

 @naturaltalent: I had a 303 RDH with the linear rail and dirt was never an issue. There was a grease port where you could force in new grease and force out the old dirty grease. I believe the rails and carriage used by Yeti were pretty much stock parts from THK.

 I think this could be easy to keep clean , CNC machines use sliders like this to guide moving beds, which are constantly subjected to metal debris & water / solvents. Maybe some boots like we see on CNC machine sliders would be a worthy addition. Also, how much debris is really getting into that area of the bike, most would be deflected from the seat tube.

 Absolutely beautiful bike. I love seeing these ornate and oddball designs. I bet it rides like a freight train as well. So cool! I wonder if it would be possible to clear-coat the rust in some way to keep the effect but stop the oxidation from further degrading the material?
  • 12 0
 Yes, we do this sometimes as well. Penetrol (available at paint stores or online) works quite well to "seal" the surface rust.

You still want to framesaver/protect the insides of the tubes, though.

 @waltworks: Hey Walt,
Couple questions, using the penetrol, do you clear coat over top of the Penetrol, or just coat with Penetrol and go?
Once the rusting/oxidation has started, wont coating it just seal it in, so it can continue to corrode?
Curious about allowing a little pPatina to develop on my motorcycle gas tank, then clearing to seal it. Purely as the tics, and hoping it turns out. Right now the tank is polished steel, which I keep maintained regularly to keep the shine. I’ve been told in the past that clearing the polished/bare steel wont adhere, and it’ll just start to peel crack without a primer/base coat
  • 1 0
 @onawalk: My advice is obviously bad and dangerous, but yes, you can let a patina develop and then seal with penetrol (couple coats if you want to). No other coating is needed. Sealing in the rust won't cause more rust, it takes more moisture and O2 to do that.

That said, I'd only do it on areas you can easily visually inspect to see if it's holding up.

The penetrol will darken the color of the patina quite a bit, so it might or might not be the look you're going for.

It’s not your jam, you’ve made that abundantly clear. No real need to go off the rails.

 The finish they got is a plain old rust, but there are steel alloys designed to not be painted called weathering steel (Corten). I wonder if there is an alloy of such steel suitable for bike frames?
Imagine the bike slowly changing colour with time www.kinley.co.uk/file_upload/images/CorTen-Steel-6a(1).jpg1
  • 1 0
 The short asnwer is no.
Weathering steel is still prone to rust without moisture control, which is what the purpose of paint, poweders and plating is for.
Corten has a yield strength of 340mpa
4130 steel has a yield strenght of 460mpa
8630 (nickel chrome moly, roughly what most high end bicycle steels) has a yield strength of 550mpa.

I have No Web presence, and, basically, no FB presence. I'm a (Very) Grumpy Old Man, that has No need to sell or promote anything. The only reason I may show my frames is because of the nagging I'm getting from a few people - riders and one or two in the MTB press that I've known for years.

I have made Long Travel Bicycles since the 70s, as well Motorcycle frames and products. And now, a class of Race Car Chassis (It's something different to 2 wheels, that I've never really had much interest in, but, it's a reasonable earner, and, interesting) I 'consult' and design for a few different overseas firms, under NDAs - They can be agreed to in both directions, as I've Never, ever wanted to become any form of 'Industry 'star' designer, as so many want to become. A few readers here may well be on bikes and suspension I've designed.

I make a few Bear Bikes frames a year, with my personal commitment to simplicity for my own bikes, perhaps 1 or 2 a month. Though various operations / repairs to the bashed up body of mine, and, Teaching commitments, have slowed that side of things down for the last 20 months. Getting old, sucks at times.

Thanks for your interest, I am often surprised that people recognize me, and Bear Bikes Australia. It's a long time since I raced, and had my Team going. Hopefully, I'll get back to racing, soon, in my 7th decade in existence.

 I think the whole "patina" thing looks like garbage. Not only that, but it's going to result in corrosion on other components, making it difficult to work on the bike.

 Rat rod MTB... I quite like that! Maybe a matt clear coat over the top now to preserve that level of rust?

 Could one substitute the slider for an undamped piston as in that other funky set-up...DW Link?

 Name translation is not "steel", but "ofsteel" as in the frame is made of steel.
