The diameter of the wheels is precisely of 125 mm. They weight 181 grams/unit, that is to say about 20.6% more than a 110 mm wheel (based on an average of 150 grams). On the other hand, there are only three wheels to wear and the total weight gain is of a little less than 10%. It is a bit more advantageous in the end. The hollowed hub provides a consequent gain of weight.
