Rising up in the ranks? The Race Lite Junior fits right in. The Junior shares the same 20 X 1-1/8" wheel size as the Mini but the 6061 alloy frame, 3 piece alloy cranks and handlebars all increase in size to accommodate growing riders. Function and control are achieved through features like integrated chain adjusters, a 100% chromoly fork, CNC alloy stem and a sealed bottom bracket for smooth operation and high speeds.
