You may consider a duplicate wheel set . Sturmey Archer has a Drum brake -cassette hub.
for non Disc Brake frames .. so the rim brakes can be replaced for the winter ,
and re outfit the Same Bike ..
they also make a front drum brake~dyno hub for light power for the dark season.
[SA drum brakes, All Weather sports Snow Cat 45mm wide rims, and the Nokian tires ,
are now in their 25th year of Occasional Use..
It Ices up here for a few weeks , some years.
