Which Hub?

I know back in the day I could abuse the hell out of Nexus/Alfine 8 speeds, had one on a Chicago Schwinn that I rode in all sorts of weather, and another on a Diamondback Tandem that was ridden through tornado warning weather [0] on top of the overall abuse of being on a tandem with two experienced riders.

[0] - 10/10 would totally do again.

Some tiagra 10 speed set up with an 8 speed cassette but its a simple enough cup and cone loose bearing design like most rear hubs made. Still though if you leave it in the rain like me the bearings will dry out and howl when the wheel is spinning, requiring new grease and bearings (since they are cheap enough to replace instead of clean and inspect).

The 'red' Alfine 8 speed hubs had extra weather sealing, that's why it was great in the tornado weather lol.

TBH if you leave it in the rain just do a repack before you ride it again, unless it's a stupidly fancy hub, a lifetime bucket of grease suitable for hub bearings is probably still under 20-30 USD per person, and if you've got the wrenches and a stand [0] a repack can be done in 20 mins or less.

Edit: to be clear, I'm talking about normal hubs, with the Alfine we did an inspection but the seals looked good and a peek done inward indicated everything was fine so... yeah those red bands were gr8.

[0] - IDK if they still make it, but the Minoura FT-1 is... pretty good balance of quirks for the lack of dollars spent, both for truing and other wheel checks...
