Fat Bike Rear Hub

Keeping up with the fatbike hub standards is enough to make one crazy. Luckily Carver Bikes is around to distill it all into the essentials. We offer two different hub bodies, one in 170mm (300g) and one in 190mm (340g). Each of these offerings has three possible configurations:

The 10×170/190 QR front hub is a great reference hub to fit most QR fatbikes with standard rear fat spacing.

The 12×177/197mm thru-axle hub is a good match for most 12x thru axle fatbikes.

The 12×170/190mm thru-axle hub fits a few imported frames whose thru axle-spacing is 170mm or 190mm instead of the more common 177mm.

Swapping end caps is a breeze, and the hubs have cartridge bearings for long life and easy serviceability. The hub can be built with either a SRAM XD driver or a Shimano-compatible freehub. 6 pawls in 24 points provide decent engagement and in typical Carver style, this ain’t no highway robbery…we’re selling each hub for $150.00! Various decals are available.
