Wet asphalt, gravel, cold, and light snow
Roller skiing almost always takes place on asphalt, which means that weather and road surface affect the feel more than many realize. Temperature, moisture, and road quality can change both grip and rolling resistance.
With the right equipment and a little attention to the surface, you can make your training both safer and more ski-like.
Wet Asphalt
When the asphalt is wet, the contact between wheels and road changes.
It can lead to:
- slightly reduced grip in turns
- pole tips slip easily
- slightly higher rolling resistance
Water on the road surface can increase rolling resistance by around 5–10% and sometimes more during heavy rain.
Tips for Rainy Conditions
- reduce speed on downhills
- plant poles more straight down into the asphalt
- avoid sharp turns
- be extra attentive in curves
Elpex roller ski wheels in rubber or PU compound generally provide very good grip even on wet asphalt, which is one of the reasons these materials are used for training wheels.
Uneven or Rough Asphalt
Not all roads are equally good for roller skis. Rough asphalt, cracks, or patches can affect the rolling feel.
Common Effects:
- vibrations in the roller skis
- higher rolling resistance
- less stability
When wheels have to roll over small bumps, energy is lost and speed decreases. This is especially true with harder wheels since they absorb less of the unevenness.
Tips
- keep your eyes 10–20 meters ahead
- bend slightly at the knees for better balance
- avoid poling over large cracks
PU wheels and rubber wheels, used in many Elpex models, also help to dampen vibrations and improve grip on poorer asphalt.
Gravel on the Road
Gravel is one of the most common causes of falls when roller skiing.
When a wheel hits loose gravel, it can:
- lose lateral grip
- slide
- in the worst case, stop the wheel
Common Places Where Gravel Accumulates
- intersections
- road edges
- after rain
- after winter sanding
Tips
- slow down when you see gravel
- roll straight through instead of turning
- avoid forceful poling over the gravel
Cold Asphalt
Temperature affects both the wheels and the asphalt itself.
When the temperature drops:
- rubber and PU become harder
- rolling resistance increases
- grip decreases slightly
Generally, rolling resistance decreases when temperature increases because the rubber becomes more flexible and rolls more efficiently.
In practice, many skiers experience that roller skis can feel 5–15% slower on cold asphalt compared to a warm summer day.
That’s why a session in spring or fall can sometimes feel significantly harder despite the same speed.
Tips for Cold Weather
- expect slightly heavier rolling
- warm up longer at the start of the session
- check pole tips (they slip more easily in cold)
Light Snow or Frost
A thin layer of snow or frost can make roller skiing very difficult.
It can lead to:
- severely reduced grip
- harder braking
- greater risk of falling
Even a thin layer of frost can make the asphalt as slippery as ice.
Recommendation
If the road is covered with snow or ice, it’s usually better to skip roller skiing.
Summary – How Surface Affects Roller Skis
| Surface | Effect |
|---|---|
| Wet Asphalt | Slightly reduced grip, somewhat higher rolling resistance |
| Rough asphalt | More vibrations and heavier rolling |
| Gravel | Risk of skidding or stopping |
| Cold Asphalt | Harder wheels and heavier rolling |
| Snow or frost | Very slippery |
Elpex roller skis use PU and rubber wheels that provide stable grip and consistent rolling resistance in many different conditions, making them well suited for training during much of the year.
