FF Rolling Resistance Meter: The Machine That Makes Rollerski Wheels Fair
On snow, everyone fights the same friction in the same track. On asphalt, the game changes. Two rollerski wheels can look identical and still roll differently. That means different speed, different training load, and in racing: different outcomes.
Buy our v-track wheels for classic
That’s why we built the FF Rolling Resistance Meter – a precision test system that measures, documents, and matches rolling resistance (RM) so athletes, clubs, and races can trust the numbers.
Bottom line: With FF wheels and skis, you get the RM you actually ordered – not wheel lottery.

What is rolling resistance (RM) on rollerskis?
Rolling resistance is the friction that slows your wheels on asphalt. Higher RM means you need more power to hold the same speed. RM affects technique, pacing, muscle load, and how “winter-like” your training feels.
- Training precision: RM decides intensity even when your heart rate looks the same.
- Fair racing: A small RM difference can become a big time difference.
- Better testing: You can finally compare intervals, skis, and athletes with confidence.
The real problem: Rolling resistance varies even within the same model
Wheel rubber, tolerances, and production variation create differences in rolling resistance. In practice, you can buy two “identical” wheels and still get different speed and load.
Why this matters
- Clubs: Athletes in the same group end up with different training stress.
- Testing days: You think you’re measuring fitness – but you’re measuring wheels.
- Competition: Teams can sort “fast wheels” and gain an unfair advantage.
We refused to accept this as “normal”. If the sport is going to grow, it needs a standard. Measurement is the start of fairness.

Our solution: The FF Rolling Resistance Meter
The FF Rolling Resistance Meter is built for one purpose: repeatable, comparable rolling resistance measurement. When you can measure correctly, you can deliver correctly.
What you get from FF measurement
- ✅ Accurate RM measurement of rollerski wheels
- ✅ Wheel matching (pairs/sets that roll the same)
- ✅ Equal training load in clubs and training groups
- ✅ Fairer competitions with less wheel lottery
- ✅ Guaranteed RM on FF wheels and selected complete rollerskis
How it works in practice
- Wheel inspection (bearings, wear, and tolerance check).
- Standardized test run under controlled conditions.
- RM result is logged so wheels can be matched and labeled correctly.
- Final delivery: wheels that roll the same – and training that becomes repeatable.
This is why we can confidently say: FF delivers the most predictable rolling resistance in the market – because we measure it.
What makes rolling resistance measurement trustworthy?
A real rolling resistance meter is not just “spinning a wheel”. To be useful for athletes and clubs, the measurement must be repeatable. That means controlling the variables that normally create wheel lottery.
- Bearings: A dry or contaminated bearing can mimic a higher RM even if the rubber is identical.
- Wheel wear: Worn wheels can roll differently than new wheels at the same labeled RM.
- Temperature: Rubber behaves differently in cold vs warm conditions. Consistent testing removes guesswork.
- Set matching: A “good wheel” is useless if the other wheel in the pair rolls differently.
That’s why FF focuses on measurement + matching—so you can trust your intervals, comparisons, and race setups.
FF RM scale (1–5): Choose the right resistance
We use a clear RM scale to help you choose the right feel and training load. This also makes it easier to compare sessions over time.
| RM Level | Best use | Who it’s for |
|---|---|---|
| RM1 | Racing / maximum speed | Experienced athletes who want the fastest roll |
| RM2 | Technique + intervals (most common) | The best all-around choice for most skiers |
| RM3 | All-round with more load | More “winter-like” resistance and strength per meter |
| RM4 | Strength-focused training | Specific strength blocks, heavier resistance |
| RM5 | Extreme resistance | Elite athletes only, maximum load |
Why this makes FF the wheel specialist
Anyone can sell wheels. Very few can control what the athlete actually gets. Our advantage is simple: we measure, match, and document RM.
- Consistency: You get the same RM today and next month.
- Trust: Your intervals and testing become comparable.
- Team fairness: A club can finally train on equal load.
Combine this with our Norwegian engineering and safety focus (including FF Brake System compatibility across setups), and you get the most controlled rollerski training platform available.

FAQ: Rolling resistance and RM (for Rank Math FAQ schema)
How do I choose the right RM?
RM2 is the best default for most skiers. RM3 gives more load and a more winter-like feel. RM1 is for race speed. If you’re unsure, start RM2.
Can I mix different RM front and back?
Yes, but only if you have a clear purpose. For the cleanest technique feel and best comparability, we recommend matched wheels.
Is rolling resistance the same as braking distance?
No. Rolling resistance affects how much power you need to move. Braking distance depends on brake design, contact, heat management, and control – especially on wet asphalt.
Does RM change over time?
Yes. Wear, temperature, dust, and bearings all influence rolling resistance. That’s why starting with measured, matched wheels matters – and why maintenance matters.
Do FF wheels come with guaranteed RM?
Yes. The whole point of the FF Rolling Resistance Meter is to deliver wheels that match the RM you ordered.
Ready to train with the right resistance?
When rolling resistance becomes measurable, training becomes predictable, testing becomes trustworthy, and competition becomes fairer. That’s why we built the FF Rolling Resistance Meter.
