Chain lube is a very good example. Everyone has to lube their chain- it is a task that if you don't do- will cost you. But there are lubes and lubes. I use a couple of well known makes and they are only a couple out of many that are suitable. There are also Lubes that are not suitable. But try and tell someone that XZ453***is not a lube but a Water displacement fluid and you are in trouble.
So chain-Lube- Clipless- helmets- Best bike to have and What is the best substitute for Blue berry Pie are best avoided.
There is no substitute for Blueberry Pie by the way.
