Engineered for competitive younger riders, the Inspyre Evo Disk Junior 18.75"TT BMX Race Bike-Black delivers race-track performance through its rigid 6061-T6 aluminum frame geometry. This machine combines lightweight construction with the structural integrity needed for explosive acceleration and precise handling during high-speed runs. The integrated component package featuring Forward Joyride cranks, Tioga Powerblock tires, and Inspyre Evo hubs creates a cohesive drivetrain optimized for minimal drag and maximum power transfer. Built with the demands of junior racing in mind, this bike's aggressive black aesthetic matches its no-compromise approach to speed and control.
NOTE: As with any complete bike, we recommend that you have a professional bicycle store build your bike. Bikes ordered through mail-order come partially assembled and need to be inspected and assembled by a bicycle mechanic. Failure to do so may void the manufacturer's warranty. Manufacturers’ warranties differ for every brand. You can check the brand's website for warranty information.
