About
The Siren was a small-batch organic release from Radical Seas, introduced in 2017. Its compact 52mm profile and finger spin hub marked a departure from the brand’s oversized H-shape debut, and it sold out quickly after announcement. The demand generated by the original Siren directly led to the wider-production Siren V2 in 2018.
The body dimensions of the original Siren are shared with the V2 — the profile and size remained unchanged between versions, with development focused on refining the finger spin hub.
