The 2021 Viral Skeptic and Derive bare metal beauties have arrived, and with them the chance to get your hands on a free Industry 9 wheelset valued at $1355. More on that later… The new Skeptic frame is redesigned from the ground up with a dropped top tube for additional standover and longer reach figures. The Viral Derive gets some subtle geometry updates too.
2021 Viral Skeptic
The 2021 Viral Skeptic titanium hardtail mountain bike frame sees longer reach figures of 440mm to 500mm over the S-XL frame size range. Built around a 150-160mm travel 29er fork the Skeptic can, as always, be run with either 27.5+ or 29” wheels. With this redesign, Viral were aiming to make the new Skeptic a more aggressive version of their all-mountain hardtail.

2021 Viral Derive
The Viral Derive remains the same in terms of its frame design. Viral chose to keep the Derive as a more traditional double diamond shape to ensure maximum frame bag sizes for the backpacking contingent.
