The 100mm XC race-ready Mag SL frame is the first product of a new collaboration between component maker Ceetec and Zerouno bikes. While we know the Swiss attention to detail of Ceetec from their presence all over pro cross-country bikes on the World Cup, the made in Italy carbon frames of Zerouno were new to us. Mixing unique carbon construction and elite XC expertise, the unexpected pairing quickly brought together the like-minded owners of both companies to create a premium quality race bike, made by hand in Europe. And it’s expected to be just the first of several more collaborative mountain bikes to come…

Ceetec owner Christian Leuenberger, actually gave us a bit of an exclusive primer on Zerouno to bring us up to speed on the bike maker and the new co-developed bikes. Founded in the states but with Italian ties, Zerouno owner Ronny Zanazzi has been designing carbon bikes made by hand in northern Italy since 2013. But with their greatest expertise and cred on the road, they were looking for more input off-road.

The two started collaborating out of mutual appreciation for each other’s work, as both are active in interdisciplinary groups working to further R&D in new carbon construction technologies in the heart of Europe. Together Zerouno brings experience working with unique carbon frame construction methods like Lunar Honeycomb materials & frame-production capacities, and Ceetec brings an attention to detail in ultralight carbon tubing layups, precision machined alloy components & World Cup race proven insight.

Zerouno Mag SL Ceetec edition – Tech Details

Together the first project has been to refine a carbon full-suspension mountain bike design that Zerouno had already begun, to fine-tune it for XC racing. That bike is now the Zerouno Mag SL, a 1970g carbon frameset fully produced by hand in a workshop in Sant Agata sul Santerno, Italy near the Adriatic coast south on Venice.

The heart of the Mag SL is its Lunar HM Carbon, high modulus construction that uses a honeycomb molded into the frame’s layup to create a lighter, stiffer tube while retaining strength, impact resistance, and the flexibility to mold the frame in complex shapes. It also allows the integration of Kevlar fibers for additional tube resistance. Apparently the Kevlar is only needed in the lo mod, non-SL frames.

Ceetec is quick to point out that as much as they are dyed-in-the-wool weight weenies, everything they develop must be race-ready. Ceetec works closely with Swiss pros like Thomas Litscher & Florian Vogel to race prove every component they make, under some of the most powerful legs in the sport, and bashed through the rocks & drops of racing in packs on the World Cup circuit.

No extra downtube protectors needed when Ceetec works on a bike, they build to withstand the harshest abuse from the strongest, fastest XC racers in the world.

Tech details on the 100mm travel Horst-link 29er XC race bike give it a tapered headtube, pressfit BB92 bottom bracket, Boost spaced rear end, two bottle cage mounts, and internal cable routing. The Mag SL frames also come with a Fox Float DPS Factory shock with remote lockout.

All of the Zerouno bikes (even their lower-spec, non-SL frames) now also get Ceetec’s super light & strong SC C1 carbon seatclamp for consistent seatpost clamping.

The Ceetec edition of the Mag SL comes with a finish called Stealth Gold Mine that pairs matte black with gloss logos & gold detailing. The bike comes in four stock frame sizes (S-XL), with a modern trail-inspired XC race geometry of a 68° headtube, 73.5° seat angle, 436mm chainstays, and long toptubes.

Developed together the Mag SL is actually being sold independently by both brands, with Ceetec managing sales in Europe for 3820 Swiss francs (roughly 3350€ via their office across the border in Germany) for the frameset & Zerouno handling US sales for $3480.

There is also a Ambizione SL carbon hardtail for $2180 / 2380 CHF (~2090€) if that’s what you are looking for. The Italian made frame shares the same Lunar Carbon tech and similar detailing, with a 910g claimed weight.

Zerouno offers a lifetime warranty on the frames – lifetime of the bike, so it even transfers down the line to future owners (not sure when it stops after being passed down as an heirloom, though.)

Complete bikes will also soon be available, including a no-holds-barred Zerouno Mag SL1 Ceetec edition complete for 9488 CHF (~8325€) that will be built up with Ceetec’s ultralight carbon wheels, seatpost, bar, and a premium SRAM XX1 Eagle race-ready groupset, or 7962 CHF (~6985€) for the hardtail.

And new bikes are already in the works for 2020!

    • Zerouno frames can be customized on geometry, carbon finishing (the exclusive 4k twill Pagani between others) and colors. Frames come with crash replacement and lifetime warranty included.
As you can see Zerouno frames are far away from that Chinese cheap frame that you mentioned. Chinese copy are available for almost any component or frame brand and unfortunately we are not an exception. Zerouno is a recognized brand in America’s and Asia but quite new in Europe. For any other doubt I invite you to schedule a factory tour in Italy or follow our social media for more info.

    • @txanjo @velofreak @sissypants & @dante: We have been assured by both Ceetec & Zerouno that the Mag SL frames are indeed made in Italy. A that the brand has had issues with copies of several of their projects being recreated in China, of course without their unique Lunar honeycomb frame construction.

      We’re quite interested to learn more, so I will try to head to their factory this coming Spring/Summer to get an inside look at how they are made. Keep an eye out in a few months time for an inside look into Zerouno’s European production.

      • Cory, thanks for looking into this! There are quite a few things that need explanation:

        1. The Workswell molds were open nearly one year ago, well before Zerouno publicly launched these models.

        2. The frames are *identical* in every aspect, not just rough copies. This includes internal routing ports, suspension bearings, derailleur hangers, silver bolt colors and hex sizes, etc.

        3. Zerouno is using 3D CAD illustrator models of Workswell frames on their website, I personally received these JPEG images from Workswell over a year ago (I’m on Workswell’s email list). It’s impossible that Workswell stole these images from Zerouno because they also sent me the actual 3D model and a similar cable routing diagram. Also, the geometry sheet that Zerouno is using is literally lifted from Workswell’s Alibaba, AliExpress, and website pages with a Zerouno logo photoshopped in. Workswell uses this geometry table format as a template across all frames, they didn’t lift Zerouno’s table.

        4. You can have Workswell manufacture a frame any way you like, including altering bladder technology and using different carbon fiber. I am not questioning that Zerouno uses their “honeycomb technology” and “Lunar” carbon to make their own road bikes in Italy, I have no clue about that and those models don’t look like Asian frames.

        If you visit their factory, it would be helpful to directly get evidence for mountain bike frame manufacturing, not just road bike frames.

        I appreciate you guy’s great coverage of everything on this site, I read it every day! This is just poor marketing by Zerouno and I want to be fair about this so other people can decide for themselves about this company.

    • The geometry for the medium is pretty good. It’s got a normal seat tube angle for people who intend on pedaling their bike, and nice top tube length that allows for fit adjustability. The stack is slightly low but not a show stopper. And it’s a really good looking frame.

  1. Looks like a pretty great bike for the money. 1970g is pretty light! The only thing that would better the design would be a pivot-less rear triangle like the Epic or Spark.

    • Zerouno had a “pivot-less” triangle on MY17/18 MAG’s. The new models have the pivot for better grip, less rebound and the suspension travel works better, especially combined with a double piston rear shock.

  2. The hardtail is actually an open mold from Workswell, the FM162. Maybe they purchased the mold from China, otherwise this is just another rebranded hardtail from china, but from workswell it’s 600 dollars shipped.

  3. Made in Italy? Really?

    Something seems off…

    The reality is that most people will never know, and just pay a fortune for these frames and Zerouno will walk off making 300% profits never having put a cent into R&D.

    If Zerouno would like to explain how they are not either using the Workswell mold for production in Italy, or not just importing from Workswell in China, they should comment here. Any Italian factory pictures?

  4. Looks like we need to get a pair of retail Workswell and Zerouno frames and section them to see if there is a difference in the build. If Zerouno use a third party mould but have a unique carbon lay-up then that’s ok(ish) but this needs a better explanation that trotting out a stock statement.
