The Optimum range from Stay Strong is our Expert level range of Freestyle bikes, The PRK is spec'd as a bike to ride at the skatepark but is ultimately an all terrain bike, using the most popular frame geometry and parts which include tapered forks with Chromoly steer tube, Double wall rims, Chromoly 3pc cranks, Double walled rims and fully sealed bearings throughout the PRK really doesn't disappoint, Removable tabs on the frame make fitting a gyro a breeze, 25/9t gearing gives greater clearance at the skatepark and lightweight parts like the nylon pedals & combo seat/post make this bike easier to manoeuvre and nail those tricks!
