I don't have a bathroom scale to weight them

 

within the accuracy of a bathroom scale. weighing just one will bounce around a 1/2 pound or more.

try weighing just one. do each of the four that way. Even if you have a digital bathroom scale that goes to the tenth of a pound, each of the four will be different. Better yet, put all four on the scale and divide by four.

 

very easy, go to UPS store and weigh them. People on evom are always going to ask the weight of the wheels.

But gram lights are not as light as Volks, these are at least 18lb-19lb each.
