km 20018.2

Replaced back tyre at km 19589 on April 6. The treads were worn through perhaps in part to a tendency of locking up the back wheel and skidding when pedestrians jaywalk.

New tyre is Cheng Shin brand, model C-1212-21, procured at a cost of $zero due to the generosity of a customer passing on leftovers from upgrades.

Drivetrain is totally toast, replacement parts on hand to be installed when value is extracted from current parts.
