Is there a site where I can find the weight of different wheels at different sizes?
Or is the only way is to just put the wheels on a scale?

ive seen that 1. i cant find ACE Strada Weights

 

Wheel manufactures may state the weight of their wheel in the description. Some do not. There is a reason of course.

 

www.tirerack.com posts all the weights of their tires and wheels. very helpful. It's actually quite amazing to see how much lighter different brands are of the same sized tire, for example; a 275/40-17, can weigh from 32lbs down to 28lbs depending on manufacturer, where 4lbs can be a noticable difference on rotational mass/unsprung weight.
