While there may be a linear relationship between increased tyre size and increased fun, this relationship only holds true when wider tyres are paired with the correct width rims. Having a three-inch tyre mated to a narrow rim makes for a squirmy, poor handling experience, and when youÕre on the hunt for additional fun, these characteristics are undesirable. Lucky for you, the new age of traction, stability, and speed has arrivedÑand its name is the Traverse 38 SL Fattie 650b with a 148 rear.

While our 30-millimeter Traverse SL is already wider than most offerings from others, the benefits of three-inch tyres become more apparent with a proper rim interface. In search for the proper width, our engineers tested various iterations, from 30 to 45 millimetres, to determine where the sweet spot lies. What they ended up with is a 38-millimeter internal rim width that turns the Traverse 38 SL Fatties into descending machines.

A wide internal rim width endows riders with a variety of advantages that are exemplified even more with plus-sized tyres. The extra width allows for more tyre volume, translating into more supple ride qualities, and better support for the tyre, meaning that you'll experience less "burping" when riding tubeless and a drastic increase in traction. After determining the proper rim width for the plus-sized application, we began designing the rim using the same low-weight, high-strength technologies used in the Traverse SL and the Control SL. With this, we started with our Zero Bead Hook design that effectively eliminates the biggest weak spot found in traditional rims, and topped it off by using high-modulus carbon fibre to keep the weight down to a respectable 1650 grams.

Each Traverse 38 SL Fattie is hand-built to our own alloy hubs with DT Swiss Revolution spokes. Inside our hubs, you'll find sealed cartridge bearings all-around, and a quick-engaging 54t DT Swiss star ratchet system in the rear, allowing you to power over rocks and roots without delay. And while machines do a decent job of building wheels, we choose professionally trained humans to build ours, as they catch various flaws that a machine would otherwise miss. You likely noticed that the 24-front/28-rear spoke count seems low for such a burly wheelset, but during testing we discovered that when built with 32 spokes, the wheels were too stiff, resulting in poor ride quality.

To further reduce the overall weight, the wheels also include the Roval tubeless plug system, which sheds an additional 50-grams-per-wheel compared to a rim strip. Finally, with the 110/148 variant, you receive all of the benefits that Boost spacing offers. By increasing the width of the front and rear hub flanges, and in turn, increasing frame and fork clearance and stiffness, you obtain a stiffer, stronger, and more durable system at a minor weight penalty.

If youÕre headed into the plus-sized wheel market, pick yourself up a set of Traverse Fattie SL 38 650Bs and notice for yourself that Fatties donÕt have to feel fat.

Update: replacement comforter is much better… really impressed with this small business
Size: Palatial King
Update: The comforter on my bed is now everything I hoped for: fluffy, warm, and wonderfully cozy. Getting here was a two-part story, and it’s the happy ending and the fantastic service that created it that I really want to share. I’ll be honest, my first comforter was a letdown. It arrived flat and thin and just never really… fluffed into the cozy cloud I was hoping for. I was pretty frustrated, which is why I left my original review. But then, something really nice happened. The company actually reached out to me directly. They were so kind, listened without getting defensive, and genuinely wanted to make it right. They sent a replacement, no questions asked, and the difference has been night and day. This new one is exactly what I’d imagined. It has a real, fluffy loft, it’s softer, and after letting it settle, it’s become the full, warm, and comfortable comforter I wanted from the start. My quick takeaways: · A small business that stands behind their work. This meant a lot. · Customer service was top-notch kind, FAST, and professional. · The replacement is clearly better quality: fuller, softer, and warmer. · It’s a completely different (and better) experience than the first. I really value when a company just focuses on fixing things. The way they handled this completely changed my perspective. While the first one missed the mark, their response and the quality of the replacement have made me a happy customer. I’m glad I gave them the chance to make it right, and I’m finally cozy under the comforter I was hoping for.

Very Nice Comforter
Size: King
So far, very happy with my purchase, (King size comforter). Just received yesterday, unpackaged and put inside my duvet, then realized the instructions recommend you place it in the dryer, (as it comes vacuum packed). I really didn’t feel like messing with the duvet again and yet the comforter still fluffed out very nice. The outer shell is very soft, it has decorative piping around the edges and the filling is evenly spread out throughout all the pockets. One of the nicest features are the tabs, located on all four corners and in the middle of each side, (to tie to the inside of your duvet, if your duvet has the little inner strings) great for keeping the comforter in place.

Just one con…
Size: Palatial King
Loved everything about this duvet: great quality, true-to-size, 8 ties and REALLY big & fluffy. It was just way too warm for us, even during the winter. Wish we could find a duvet this full that was cooler.
