The top weight plate assembly on the Cybex Eagle NX and Cybex Prestige line is 10 lbs. and the Twist Select knob can choose from an additional 0, 5, 10, or 15 lbs which a
llows the user to adjust weight quickly and simply in 5 pound increments
Therefore, with just the top weight plate assembly you go from 10 lbs, 15 lbs, 20 lbs and then 25 lbs. The next step would be 30 lbs with the weight selector pin in the first weight plate (which weighs 20lbs) and the Twist Select knob set to 0.
See the following article Strength Weight Plates for more details on weight plate dimensions and related weight.
