9zero7 fat bike team issue superlight silder aluminum carbon rims (7)

It seems that no matter where I go with a fat bike, people still look at it and say,”man, that must be heavy!” Only for them to pick it up and go on to exclaim that they can’t believe how light it is. Imagine my surprise when I was that person after picking up the 9:zero:7 Team Edition built up for co-owner James Stull.

It wasn’t just the build that was light, however. The frame sees a number of updates that find their way across the Whiteout range. But it also gets a few improvements of its own…

In order to get the weight down, way down, 9:zero:7 made a number of changes for all Whiteout frames, but the Team Build sees the addition of T1000 carbon fiber in addition to the standard T700. That, combined with redesigned dropouts, and a new head tube result in a frame that is impressive 1.25lbs lighter. While the weight is a fun feature, we are most excited about the new dropouts that no longer have a threaded nut, but more importantly have what looks to be a drastically improved rear derailleur hanger for improved shifting performance.

Jamey’s bike was built-up for racing with a lightweight parts group, but without anything too crazy. Which is why the weight seems incredible at 18lbs 150z (8.59kg). To get to that weight though, first you’ll have to drop $3,200 on the new Team frame.

If that’s still too rich for your blood, the standard Whiteout sees all of the same improvements without the upgrade in carbon fiber. It does get new colors with a UD carbon finish showing through underneath though. Pricing for the standard frame remains the same with complete GX1 builds starting at $3699.

Over on the aluminum side, well, the Slider side, their belt drive compatible frame receives a substantial overhaul. Now using a 170mm rear spacing thanks to the wider Rohloff hub availability, the frame has a beefed up rear end, new chain stay yoke to clear 5″ tires on 100mm rims, and new hydroformed tubing on the upper half of the bike. Also, while the Whiteout frame and fork remain non-suspension corrected, this one is (and 15×150), making it Bluto compatible. And all of this is delivered for $999 for the frames.

The bike was also secretly rolling on their prototype carbon 100mm rims. Few details were available other than they are soon them.

  1. “9:zero:7 claims they will be stiffer than the HED BFDs.”

    How do you quantify that when you slap on a 4″+ fat bike tire? I’ve never heard anyone rolling BFD’s say, ‘dang I wish these were slightly stiffer’.

  2. Look, I’m a bit of a weight weenie, so I get where the craziness on weight here is coming from. But, any sort of stiffness on a rigid fat bike is a little misguided, no? I mean, 4″ tires at single digit PSI kinda negate EVERYTHING ELSE YOU COULD POSSIBLY DO.

  3. Interesting. I quote the last part of the post about the prototype rims claimed stiffer than BFD’s and it magically disappears. After the omission we’re left with “Few details were available other than they are soon them” eh? come again? Maybe 907’s marketing department got chewed out by the designers for making false or irrelevant claims.

  4. Have you ever held just a HED carbon rim in your hands? I have. Felt like I could have snapped it in two without much effort. It was really, really flexy. Mine you, you can do the same with a Surly Holy Rolling Darryl rim. Still pretty flexy, but nothing compared to the HED. The HED’s have a really low spoke tension max for this reason. It wouldn’t be too hard to make a stiffer rim than the HED’s.

  5. If you’re worried about how stiff a 19lb fat bike is, you’re doing it wrong. There’s got to be compromises at that weight unless your budget is unlimited. Fortunately, much of the flexibility would be damped by the mass of rubber. The HED rims have a typical spoke tension limit. Considering the weight of the B(F)Ds, it’s generous, to say the least. Realize that the strength of carbon fiber composite is best displayed when the structure is in tension. Bare rims, especially single wall varieties, can’t possibly demonstrate every quality of the complete wheel.

    Your comparison to ANY ALUMINUM rim is invalid, as it attempts to show a meaningful relationship between the behavior of aluminum and carbon fiber composites, at significantly different weights and constructions, at an undetermined load, outside of the intended use, or within a complete structure. You could certainly load a HED rim until failure, but I will bet, at identical loads and deflections, that the Surly rim will deform plastically, long before the HED fails.

  6. Your Face – This is about air volume trumping any sort of slight variance in rim stiffness. Send Jesse LaLonde from Twin Six a note about what thinks of his “really-really flexy” HED wheels. The guy is like the Eddy Merckx of Fat Bike racing.

  7. I am commenting in to try to explain where there might be some confusion about rim stiffness.

    None of us at 9:ZERO:7 have ever claimed that our new Storm 100mm Carbon Rim is more stiff than the HED BFD 100mm Carbon Rim, in fact, I don’t believe that any of us have even held a HED BFD rim! HED is an amazing company with an exceptional team of employees that we enjoy working with. 9:ZERO:7 and HED have collaborated on multiple projects including our new sub 19lb 9:ZERO:7 Whiteout Team Edition and we would do nothing to tarnish their name or criticize their products. Last year at the Fat Bike Birkie(The Largest Fat Bike Race in the World), all three 9:ZERO:7 Factory Team Riders on the Podium rode HED Big Deal Carbon Rims.

    That being said, stiffness was a priority in the design of our new Storm 80mm and 100mm rims along with durability, tubeless compatibility, and low weight. I love my HED wheels but I’m really excited about our new 9:ZERO:7 Storm Rims.

    Kernel Flickitov- You are correct, Jesse LaLonde is incredibly fast!

  8. Steve– The Team Edition bike is not a “strider” you’ll need to BYOP to the party — It’s pretty standard to weigh bikes as they’d be sold, hence no pedals. BUT, there was (and is) plenty of Stan’s in those tires!
