Apologies in advance if this is something that has previously been asked..

I bought the powerblock urethane 33 (3-21 lbs) about a year ago, and I’ve out grown them (yay!), unfortunately I no longer see the U series on the website, and I was hoping to buy an expansion set and not a whole new series.

Was wondering if anyone knew anything about this, or could recommend a place that might have the U series expansion set.

Thanks y’all!
