Can anyone advise on the specs, dims, etc. of the weight rings the RD-1 uses? I recently picked one up and would love more mass. They’re rings of overlapping spring steel leaves, yeah? Like what one may see holding a hydraulic seal in place?

I reached out to BC directly but haven’t yet heard back. Thx!
