With the recent introductions of production carbon fatbikes from Salsa and Borealis, 9:zero:7 looks to be getting in on the action with the all new Whiteout carbon. All three bikes seem to have a different rear axle system with Salsa using a 177x12mm thru axle, Borealis with a 190mm QR rear end, and 9:zero:7 with a 190mm thru axle rear end that is capable of running 4.8″ tires on 100mm rims. There is also a thru axle up front in a tapered carbon fork.
The Whiteout will be offered in S, M, and L frames with 9:zero:7 saying it will be light. More details when we have it.
