Nextie Xiphias carbon wheelset
A complete wheelset built around the Xiphias rim. A pair of Xiphias rims on Nextie's own Rollingstar II Fatbike hubs, in 7 sizes (55-105mm wide), with Sapim spokes and black alloy nipples. Nextie molds the rims in Xiamen and sends us the parts as a kit, and we lace, tension and true both wheels by hand in our Georgia shop.
ProWheelBuilder is an independent wheel builder in Georgia and a Nextie dealer, not the maker of the parts: we check your axle, freehub and size choices before the order goes in, and build the pair when the kit arrives.
Building your pair
The Nextie Xiphias wheelset is sold as a matched front and rear pair: both wheels use the same rim size and wheel diameter.
Sizes, wheelset weights and prices
Wheelset weight is the complete pair as built: both rims, spokes, nipples and the hub set, from the lightest spoke and hub choice to the heaviest. Prices are for a matched pair on the least expensive hub.

The rim
The Xiphias is the lightest fat-bike rim Nextie makes: a single-wall carbon rim in eight widths, from a 55mm 27.5+ crossover to a 120mm float rim, from 425 to 600 grams. On a fat bike, where the rim is the heaviest part of the wheel, that is where carbon saves the most.
There is no UCI approval for fat-bike wheels; the approvals listed on the rim page are Nextie's road and gravel certificates, from the same factory and test lab. Nextie rates these rims for a maximum system weight of 134 to 185 kg (rider plus bike and gear). The Nextie Xiphias rim page carries Nextie's published lab results, test videos and certificates in full.
Hubs, spokes and drive
Hub choices: Nextie Rollingstar II Fatbike 15x150 / 12x197, 36-tooth engagement, 6-bolt rotor mount. The hub sets the drilling, 32H, and both wheels use the same set.
Spokes are Sapim: the round Race (2.0/1.8mm double-butted) for durability, or the bladed CX-Ray for less weight and drag, both with black alloy nipples. Freehub bodies: Shimano MTB (HG), SRAM XD, Micro Spline 12S.
Finish: matte or glossy carbon. Decals: None, Outline White, Solid White, Solid Black, Glossy Solid Black, Solid Sunset, Solid Sky Blue, Solid Lilac, Solid Chromium.
Other Nextie fat bike wheelsets
Wild Dragon (83mm inner, from 1938g); Black Eagle II (58mm inner, from 1900g); Drunken Rhinoceros (120mm inner, from 2340g)
Value
Carbon fat rims from the big names cost more than many complete fat bikes.

Warranty
Manufacturer's warranty. Nextie warrants this product against defects in materials and workmanship. The duration, conditions and claim process are set by Nextie and can change without notice, so ask us and we will confirm the current terms before you buy.
ProWheelBuilder. We build this wheelset here, so our one-year wheel warranty covers it, alongside Nextie's warranty on the parts. Inside that year, broken spokes are replaced no matter how they broke, and the wheel labor is ours - truing, re-tensioning or a full rebuild. A rim or hub failure that Nextie covers, we claim for you and see through; one Nextie declines is answered with an eligible replacement at 25% off retail. Shipping each way is yours.
Full terms are on our Policies & Warranty page.
Nextie Xiphias wheelset questions
What does single-wall mean on a fat rim?
The Xiphias has one wall between the tire bed and the spoke bed instead of the two of a box-section rim. It saves a lot of weight on a rim this wide; the double-wall Black Eagle, Wild Dragon and Drunken Rhinoceros are stiffer and rated for more weight.
Which Xiphias width should I choose?
Match it to your tire. Nextie's tire ranges are in the table: roughly 55mm for 2.8 to 3.8in, 80 to 85mm for 3.5 to 5in, and 95mm and wider for 4.2in tires and up.
Can I buy one Xiphias wheel on its own?
Not from this page: this wheelset is sold as a pair. A single front or rear wheel on this rim can be built in the Custom Wheel Program.
Which hub should I choose?
The wheelset is built on the Rollingstar II hub listed above, matched to the frame spacing.
Is ProWheelBuilder the manufacturer of the Nextie Xiphias?
No. Nextie designs and manufactures the rims and hubs. ProWheelBuilder is an independent wheel builder in Georgia and a Nextie dealer: we check your choices before the order goes in, hand build the wheelset from Nextie's kit and handle any warranty claim.
