Testing of tyre rolling resistance using rollers - Part 1

 A previous blog post from 2020 described my measurements of tyre rolling resistance that I did using the Virtual Elevation outdoor method.Tyre rolling resistance coefficients can also be measured using rollers instead, and I've been keen to try that method ever since reading about...
