The original inspiration for the Wolverine was “monster cross”, but it is seriously so much more. Its geometry is stable enough for off road touring, but sporty enough for all-around adventure and gravel riding. With its sliding dropouts, you can run single-speed, derailleur gearing or hub gearing.

2023 brings our version 4.1 A-Type that adopts flat mount brakes on the frame and optional fork.

The A-Type is a little more "modern" than the B-Type. It adopts 142mm rear thru-axle and a 44mm headtube that will fit 1-1/8 straight steerer or tapered steerer with the proper headset type (better compatibility with third party carbon fiber gravel forks); however we removed the seat stay break, so it isn't Gates belt-drive compatible like the B-Type.

Uses full length cable housing, so it does not have the old school downtube shifter bosses. (See chart in photo gallery for other differences between A and B)
