I have defeated the software and am back! Righto, fridays video re shot, hurridly on a busy monday.

A couple of groovy low friction updates, then covering the main information in the ever more confusing world of 12spd chain and drivetrain system standards. May this help you know what chain options you have for your 12spd drivetrain. Are their faster options? More durable options? Potential issues with mix and match etc - things are not so simple like 10 or 11spd days. Not helping is Sram having two extremely similar Flat top 12spd chains, that are apparently not cross compatible. Nor does sram chain model naming help ensure people needing to buy a new sram chain buy the correct on.

Never fear, low friction is here. Let me know if this helps.
