AEKO is an Italian Bicycle company founded by Paolo Azzolini. They make some pretty incredible bikes and Paolo was an early adopter of fat bikes in Italy. The Zirculum carbon rims caught my attention several years back and every now and then, Paolo and I would trade emails about how things were going. We talked […]

Spring Bike Safari – Made U.P. Lake Ehfect
I’ve had a plan to get up to the UP to ride for at least a couple of years. Ever since Jason at Bearclaw Bikes announced their drop-bar fatty called the TOWMAK I dreamt about returning to the vast Huron National Forest and its hundreds of miles of rustic roads, trails, and beaches. So when […]

The Lightest Fat Bike Wheelset in the World out of the box video.
We recently got word that a set of Made in Minnesota HED/Berd/Onyx Racing fat-bike wheels was on the way. We set up the camera and shot a quick ‘out of the box’ video to share some stoke for what HED Cycling bills as the lightest fat-bike wheelset in the world. A sub-2000 gram wheelset is […]

I’ve been riding a set of Fatback’s Big Su 27.5 Carbon Wheels for the last month on my Fatback Corvus FLT. March is a great time to experience virtually, all four seasons in America’s Dairyland. I just mounted my third different set of tires on our test wheels to keep up with the rapid transition […]

Cantu Rumble Wheelset Review by Adam Blake
An immediate difference… that’s what I noticed after installing the Cantu Rumble wheelset on my Salsa Cycles Beargease. The question was: what was I noticing? In my initial Cantu review, I touched on the fact that double-wall carbon rims aren’t much, if any, lighter than single wall alloy rims that are available and quite popular […]
Fatback 27.5 Big Su Wheelset Review
It’s kind of funny that I’ve reviewed the 26″ version of this wheelset and never really asked about the story behind the Big Su Name. So when it came time to write the review of the 27.5 Big Su Wheelset, I asked Fatback’s Head-Honcho, Greg Matyas ” I’m curious to learn the story behind the […]
CABDA MidWest SitRep
I made a trip to what I like to call the belly of the beast, Schaumburg, Illinois, yesterday to browse groovy cycling wares at the CABDA Midwest Expo. CABDA has been around for a long, long time. Way back in the last century, the shop that I worked at (ABC Cyclery) used to prep and […]
Fatback Big Su 27.5 Wheelset
We’re field testing a pair of solid, lightweight Big Su 27.5 wheels from our amigos at Fatback Bikes up in Alaska. We tested and reviewed the 26″ version of Fatback’s Big Su Wheels back in 2018. You can read how they performed here. The twenty-six inch set of big su’s received high scores so when […]
Cantu Rumble 27.5” Fat Bike Wheels Initial Review – by Adam Blake
“Its totally a thing.”… generally that is my response when people approach me about carbon rims on a fat-bike and their viability. A lot of people immediately focus on weight savings in carbon vs aluminum rims, but with companies removing material from aluminum rims, and utilizing single wall designs, the weight savings from a reasonable […]
Fatback/Knight Wide Ride Wheel Review – By JP Syverud
Back in January the Secret Underground Fat-Bike Test labs received a set of Fatback Carbon Wheels. What can I say? Fatback continues to innovate the market with their latest product. This time they partnered up with Knight Composite to make this glorious love child of a carbon fat bike wheel set. I was super pumped […]
ENVE M685 Wheelset and Fat Fork Review – by Julio
Way back in December I wrote an introduction to a new wheelset and fork from the carbon fiber maestros over at ENVE. This was big news given that one of the biggest names in carbon fiber was (finally) getting into the fat game. You can read all about the M685 wheels and Fat Fork here […]

First Look – ENVE M685 Fat-Bike Wheelset and Fat Fork
While there are currently a quite a few rim/wheel options out there in the fat-bike universe, one major player in the high-end carbon market has been noticeably absent – ENVE Composites. The same can be said for fork offerings … lots of choices but no ENVE. Well, that’s now changed with the launch of the […]
Fatback Big Su Review
Back in September, we spotlighted the Fatback Big Su Wheelset and after a couple months of gnome roping, we’re back with a full review. I’ve been running the Big Su’s on my ‘murdered out’ Fatback Corvus FLT – [code name: ten beers] with a set of Schwalbe 26×4.0 Jumbo Jims (tubeless). I took a […]
First Look – Fatback Big Su 26″ Wheels
Back in the springtime at Sea Otter, muh man Fuzzy showed me Fatback’s new Big Su Aluminum Tubeless Ready Rim. The new rim weighs in at an ultra-svelte 640g. I’m not talking about ‘light for an alloy set of wheels’. I’m talking lighter than a bunch of the double wall carbon wheels on the market. Last April […]

Product Spotlight – Framed Carbon Wheels – By Andy Amstutz
Carbon fibers according to Google are a material consisting of thin, strong crystalline filaments of carbon, used as a strengthening material, especially in resins and ceramics. Google says nothing about being a kick ass rim material for fat bikes. I’ve been riding aluminum rims for years and jumped at the chance to test […]
Blackjack Bikes Fate Review
Back in July, I began testing my Amigo Jack’s new Blackjack Fate. We published a first look about the Fate in August – https://fat-bike.com/2016/08/first-look-fate-from-blackjack-bikes/. I pursued this review to see if an open mold, carbon fat-bike could hold a candle to the performance of two proprietary, high end, carbon fat-bikes that I spent time testing last […]
Fresh from the Show Floor – Interbike 2016
Direct from the Mandalay Bay Resort and Casino, we have all of the freshest fat and plus bike hotness for y’all! I was going to try to separate the plus from the fat, but there’s a lot of cross-over. I saw fat-bikes that were designed to run plus and even one plus-bike that can run, […]
REVIEW – Atomik Phatty 85 Carbon Rims w/ I9 Hubs by Steve Meurett
The winter only fatbike realm has long since been left behind-thank goodness. This is not news-most of us who ride fatties, do so year round because they just work…are fun…go anywhere…handle well…go fast? Well, of course, if properly outfitted. Within a short period of time, manufacturers have evolved the stock fatbike into a do […]

Product Preview ♦ Atomik Phatty 85 Carbon Rims w/ I9 Hubs by Steve Meurett
There is hardly anything as sexy as slipping some carbon fiber of some sort onto your fatbike ride. Sure, fatbikes in the early days were pretty “big boned” and maybe not the most performance orientated as they are evolving to today. In the past, why slap spendy light pieces and parts on a tug boat […]

Back in July, I was dispatched to Utah for a mission, to document and photograph, Surly’s new fat-bike.
