"The original Following was designed as a short travel playful trail bike, but to our surprise you all thought it was a mini DH bike, so we decided to add a trunnion mounted metric piggy-back shock, boost spacing and a few other things to handle higher speeds and bike park style riding. Moving to 148 x 12 spacing and a 1x drivetrain allowed us to follow what we have done with the Calling, Wreckoning, and Insurgent, adding stiffness in key areas while maintaining the compliance necessary to make this thing track in the roughest corners. The trunnion mount allows the shock to run on two of our linkage bearings, which not only makes the initial stroke smoother but allows the suspension to be more active throughout the travel. Geometry stayed very similar with the exception of an additional 20mm in reach, which opens up the cockpit a bit and provides a longer more stable wheelbase while maintaining our signature berm slashing 430mm chainstays. The leverage rate curve has been slightly updated to handle those days when landings are an oversight. We have also added support for various piggy-back, coil and inline shocks so you can build a lightweight XC/Trail slayer or a Pacific Northwest shredder."
