What started out as a tri-spoke full carbon wheel concept became a simple, extremely light carbon rim.

“We started out with a traditional shape like what we were used to, but we weren’t going to get to a weight that we wanted,” said Steve Hed. “We knew we wanted tubeless and we wanted it to be as light as possible. We started out with a target of 550g. Then we got to 450g, now we’re 420g and we’re not sure how light we an go yet.”

It uses a twin channel system. You put the bead in the center and it settles into the inside channels. At that point, it’s sealed and you just start pumping it up. Once it gets to a certain pressure, it just pops out to the outside bead hook. Hed says there are a lot of pieces in the mold to get the internal shaping right.

These are set up with the 45 North tire and just one scoop of Stan’s sealant and Gorilla tape just over the spoke holes. He says it can hold on as low as 5-7psi.

A complete set of wheels is likely to come in just under $2,000. They’re still testing the water on final pricing and whether they’ll sell just rims. They’re not quoting pricing for rims, but back out the math a bit from a complete build and you’re likely looking at about $800 per rim. Shipping in November.


He’s still considering final spike hole placement. A single straight line is easiest to seal, but they’re looking at how well that builds up.


They had a gravel bike at NAHBS to showcase the new Ardennes+ disc brake wheels, they just didn’t call a lot of attention to it. It’s built by Erik Noren of Peacock Groove, and they’re likely going to offer it for sale. It’ll be $1,795 for frame and fork.


The fork is made to fit 650B mountain bike wheels and tires.


Thru axle front and rear, so all the disc brake hubs are convertible from QR to TA.


Also, all disc hubs will be CenterLock instead of six bolt…like on the Ardennes+ shown at NAHBS (more info here and here).


The new Ardennes FR that takes the tubeless ready bead hook of the wider “+” models and puts it on their lighter 23mm wide (17.5mm inside) rims. They’re 25mm deep and weigh in at 420g each. Complete wheelset is 1,335g. Retail is $1,400.



They use a new, lighter front hub with better bearings. Spokes move a bit further outboard so it can be stiffer, and overall it drops about 10g to come in around 70g.


And did you know they do anodized color accents for their hubs?



  1. I’m glad I held our and didn’t buy the Borealis rims. Saved 130 grams!

    Srsly though, how wide are these? (I ask with the same profane curiosity I would use to ask how many horsepower a particular Ferrari has)

  2. Either Hed didn’t do their research very well or they don’t intend those rims to be used in the winter: Holding “on as low as 5-7psi” will not be enough. I’m a skinny dude (140 lbs soaking wet) and I occasionally run below 3 psi in my rear tire, and an unreadable pressure (maybe ~.5 psi) in the front in the winter just to get enough float in certain conditions.

  3. Frame builder is Eric Noren, not Eric Nord.. LOL

    Cool the bike is designed to run 650b as well, not surprised coming from Eric. Super forward-thinking guy! Makes it super versatile!

  4. @Jason: Fat tires are the only way to ride on sand, snow, or non-manicured trails in general. Fatbikes are the only true “go anywhere” bikes in existense. Unlike fixies, these bikes actually have a purpose.

  5. Yeah but can I mount these to a FixxiePhatty? I’ve got some PBR and Skinny Jeans. I think I can find thermal Skinny Jeans for the winter, would this make my Skinny Jeans look even Skinnier?

What do you think?
