The year of 2018 saw the introduction of a new series of Xiphias (Swordfish) single wall fat bike rims in 26 and 27.5 with widths from 65mm to 105mm. That pretty much gave NEXTIE the fattest collection of fatbike wheels anywhere – as long as you're okay with carbon fiber! 

[Xiphias series] (single wall):

26" 65mm: 440g

26" 85mm: 530g

26" 95mm: 565g

26" 105mm: 600g

For all Premium Edition rims, certainly we do improvements over traditional-tech carbon rims.

1. Materials: T800 carbon fiber added to Premium Edition rims;

2. Optimized the layup system mixing T700 & T800 carbon fibers after many times of producing, testing, producing and testing, found a best impact resistance over durability and tenacity;

3. We made a single mold to layer up the spoke bed wall. The flatness of rim channel surface significantly improved so that thickness at each spoke hole completely consistent. It effectively prevents the carbon loop of spoke hole wall from shifting;

4. Each of rim would be attached with a card showing the flatness and roundness. The flatness and roundness are controlled quite well. Flatness is controlled within  (+/-0.15mm), and oundness within +/-0.2mm, easier to tune when do wheelset assembly;

5. Three year warranty offered for Ultralight and Premium Edition rims.
