Overview

The Viral Bikes Skeptic is a radical departure from the norm, playing in a space that only few have ever dared. This play bike is built around a 120-140mm travel front fork, new Boost spacing rear triangle, and a Pinion drivetrain that effectively puts an end to poor shifting performance and drivetrain maintenance. Founded by Porsche gearbox engineers, Pinion is a cutting edge gearbox company building amazing bicycle transmissions in Germany. The Viral Bikes Skeptic frame kit will come stock with their P1.12 twelve speed internal gearbox transmission. This amazingly robust and nearly maintenance free system was borne to defy current mountain bike standards and laugh in the face of traditional drivetrains. It’s sealed, completely, from the elements and only requires a fluid change once every 6000 miles or once a year, whichever comes first. In addition, the Pinion gearbox comes with a 5 year guarantee that your shifting will be perfect, no questions asked, as long as the fluid is changed within the prescribed schedule. Coupled with the Gates belt drive, the Skeptic is nearly maintenance free. Just ride, rinse, and repeat.
