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.
The primary differences between the 3.0 and v. 4 Type-A and B is a new 46cm size, an extra set of water bottle bosses, and additional stack height on most sizes. The Type-A ALSO adopts more modern standards such as 142mm rear thru-axle and a 44mm headtube that will fit 1-1/8 straight steerer or tapered steerer with the proper headset type. There is NO frame break for Belt-Drive like the B-Type has. (See chart for other differences between A and B)
