Their formula is quoted in the corsa Graphene 2 review:

https://www.bicyclerollingresistance.com/...oria-corsa-graphene2

Use the formula: RR (watts) = CRR * speed (m/s) * load (N) to calculate rolling resistance at a given speed and load

the standard test conditions are described in:

https://www.bicyclerollingresistance.com/the-test


Some facts about our "standard" test:

• 77 cm drum diameter.
• Standard test drum speed of 200 RPM which translates to a speed of 18 mph / 28.8 km/h.
• Diamond plate drum surface.
• 42.5 kg load.
• Computerized measurements.
• Controlled temperature between 21.5-22.5 °C / 70-73 °F.

If you scroll down on bicycle rolling resistance.com to Rolling Resistance Test Results it gives a CRR value at set tyre pressures. That said the CRR will be effected by the road surface you are riding on.

Edit: Posted too slow but mine is simpler!

Awesome. Thanks! Figured it was a simple answer.
