Stay Strong Optimum PRK BMX Bike

From their Expert level range of the bikes, the Stay Strong Optimum PRK BMX Bike is spec’d out as a skatepark ride but it’s ultimately at home on any terrain. It boasts popular frame geometry and parts which include tapered forks with chromoly steer tube, double wall rims, chromoly 3-piece cranks and fully sealed bearing throughout so 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!
