  • [Xiphias] 27.5" Fat Bike Single-Wall Carbon Rim 80mm 580g


Fat bikes are quite similar to regular bikes, but have much wider rims and larger tires that provide enough support to ride on the snow or sand. Fat bike is especially suitable for winter cycling. With wide tires, you could easily float on top of the snow and make your way through the winter.

This single wall carbon fiber fat bike rim NXT27XS80 was designed and developed in 2021. It's super light, onlg 580g weight. Its design concept refers to our well-known Wild Dragon double wall fat bike rim. It is strong due to the stable construction of triangular cross-section. To make the wheel assembly more perfect, the spoke holes of the rim are drilled at an angle. The axial direction angle and the radial direction angle are 8 degrees and 6 degrees. The profile drawing is as below.

The tire size for this model of rim is recommended at 3.5" ~ 4.8". The tire pressure is recommended at 8 ~ 30 psi.
