About
When the original PK Ripper burst onto the scene in 1979, it took the BMX world by storm & set a new benchmark for radness. Here we are 40+ years later and it’s happened again with the PK Ripper 27.5, designed by the man himself, the PK of “PK Ripper”, Perry Kramer. This ultra-cool bike features tubeless ready 27.5” x 2.5” Vee Speedster tires, sealed internal headset, internal cable routing, Tektro hydraulic disc brakes, Oakley B-1B grips, and of course Perry’s stamp of approval. This is the PK of the future!
