- Wider tires at lower pressure are the single biggest winter upgrade you can make
- Full-coverage fenders with mud flaps save your drivetrain and the riders behind you
- Wet lube and frequent reapplication beats dry lube below 5°C
- Lights are a legal and practical requirement — front, rear, and ideally a backup

Start With the Contact Patch
The cheapest winter upgrade isn't gear — it's letting 10-15 PSI out of your tires. A wider tire (28mm for road, 32-35mm for mixed surfaces) at lower pressure deforms over wet metal, frost, and painted lines instead of skating across them. The goal is a contact patch the size of a thumbprint, not a fingernail.
Run tubeless if your rims allow it. Sealant handles the small glass and grit cuts that winter roads deposit, and you can drop pressure further without pinch-flat risk. If you're on tubes, consider going up 2mm in width — it's the same effect, just with rubber instead of air.

Fenders Are Non-Negotiable
Full-coverage fenders — not clip-ons — are the foundation of a winter bike. They keep spray off you, off your drivetrain, and off the riders behind you. SKS Longboards and PDW Full Metal fenders both extend close to the ground; cut a mud flap from an old inner tube to close the last 10cm gap.
A dry drivetrain lasts three times longer. The same chain on a fendered bike in winter will easily outlive the same chain on an unfendered bike through one wet week. If your frame has no fender mounts, consider clip-ons for the rear at minimum — even partial coverage helps.

Match Lube to Temperature
Winter grit + wet + salt = drivetrain paste. Wet lube is stickier, attracts more grime, but actually stays on the chain in the wet. Clean and reapply more often than summer — every 100 km in nasty conditions is the rule, not 300.
Wipe the chain down after every wet ride. A 10-second rag wipe removes 90% of the abrasive slurry that would otherwise grind through your cassette.
Chain lube by winter temperature range
| Lube type | Temperature range | Reapply |
|---|---|---|
| Dry/wax | +10°C and up | 150-200 km |
| All-weather | 0°C to +15°C | 100-150 km |
| Wet | -5°C to +10°C | 80-120 km |
| Synthetic wet | Below -5°C | 60-80 km |

Lights Are Safety, Visibility, and Legal
A front light of at least 500 lumens and a solid rear of at least 50 lumens is the floor. In winter, daytime running lights matter — drivers aren't expecting cyclists in low-angle sun or grey weather. Pulse mode extends battery life and stands out against brake lights.
Carry a backup. The tiny silicone Lezyne or Exposure lights weigh nothing and save you from the 30-minute walk home when your primary battery dies mid-ride.

Don't Forget the Touchpoints
Wrap a layer of thermal bar tape (Lintan, Lizard Skins 3.2) over your normal tape, or use full silicone grips. Cold fingers lose dexterity and braking power — gloves matter more than jersey thickness.
A winter-specific saddle with less padding and a cut-out handles wet bibs better than plush endurance saddles. Wet chamois on a soft saddle compresses and creases; a firmer saddle stays the same shape wet or dry.
