Winter riding gets much easier when the setup is built around the weak links instead of around bravado.
Protect the points that fail first
Hands, feet, and visibility are usually the first things to break the ride. Solve those before buying niche gear.
Match the bike to the grime
Fenders, lights, a cleaner drivetrain routine, and slightly more forgiving tire pressure often matter more than marginal clothing upgrades.
Keep the routine realistic
If winter maintenance feels like a burden, simplify it. A bike you will actually keep riding is better than a perfect setup that sits untouched.
