When it came to starting work on our very first full-suspension slopestyle rig, we wanted to take our time to ensure that this thing rode just as dialed as it looked. The Siren frame is crafted from premium grade 6061-T6 hydroformed alloy and features a short chainstay length and responsive geometry, allowing you to really throw this thing about as if it was a hardtail.

The Siren uses RockShox suspension front and rear for a smooth ride that gives you enough cushion on heavy impacts without sacrificing speed or feel. Backed up with the finest components from Race Face, SRAM, and Maxxis, the Siren is the perfect "do it all" weapon for sending it at the bike park, cruising through the trails, or pushing for the podium at diamond slopestyle events.
