- We present a revolutionary method to test chains by measuring articulation friction - the primary contributor to roller chain losses. Our pendulum method gives higher accuracy (0.012%) than the best forgoing dynamometer methods (0.2%). Funded by Reynold Plc, this allowed subtle differences in chain performance to be assessed leading to the development of ultra-high efficiency chain drives. This helped British Cycling win 6 golds at the Rio Olympics leading to further funding from Reynold/British Cycling Federation for Tokyo2020, and we exhibited at the Royal Society Summer Exhibition 2016. The test accuracy is demonstrated via a thorough analysis of measurement uncertainty.
