💡 Why swap steel rollers for ceramic versions in drivetrains?

- Carbon steel degrades quicker when oil breaks down from heat - Ceramic mix cuts overall rotating mass for snappier gear changes - Non conductive surface blocks electrical noise in sensor areas - Budget friendly upgrade covers long service life requirements ✝️
