7 year old Giant Tourer Lite...3 hours of cleaning/ regreasing/ lubing, White Lightning wax on the chain + GT85 elsewhere. Result? As the old submarine captain would say, "Rig for Silent Running"! The bike is so smooth and quiet I'm amazed.
No wonder GT85 is approved by the MOD for submarine maintenance :-)
I usually do cleaning stuff on a strictly "chore" basis but there is something satisfying about cleaning a bike properly. Clean bikes are as nice as fresh bedding :-)
