I have several IGH bikes* I also have an old MTB with the Studded tires on it.

If I had as long a winter as you in the northern inland states did

I'd build a new wheel set with the recent S-A 4 or 5 speed drum brake hub , but as I'm on the NW Coast,

the drum brake freewheel hub is just fine , proven reliable over past 30 years..

* Rohloff Disc another with Magura Rim Brakes , 1 V, (Sram i-9) and the Brompton M3L, side pulls
