Our PRK model starts with its own frame/fork specifically designed for transition parks. The frame features a slightly shorter 12.6” rear end, a lower 7.25” stand over height, and a slightly more relaxed 75.3 head angle than our all-around S1 geometry. The PRK fork features a more responsive 25mm offset, a peg clearance cut, and a longer 172mm steerer tube to accommodate a gyro. With two top tube lengths to choose from, 20” and 20.5” both with 8.7” bars and their own crank lengths, 160 and 165mm respectively. Pivotal seats, alloy sprockets, and double wall rear wheels round out our purpose-built PRK models ready for the great indoors or wherever you need a responsive bike ready to push boundaries on.
