Overview
About this bike
Make Rob Wise's fluid street style your own with GT's Wise Sig street bike. The full chromoly steel frame features a high-strength down tube gusset so you can roll away from hard landings, while removable brake hardware lets you set up the bike as clean as you want. The chromoly fork uses a one-piece CNC'd steerer for extreme front-end strength. GT pulled out all the stops, spec'ing the Wise Sig with a full array of their own high-quality BMX parts, including GT Smith bars and stem, super grippy pedals, and a Pivotal seat and seatpost. Do Rob proud and dominate the city streets.
