About This Product: Inspyre Evo-C Disk Junior 18.75"TT BMX Race Bike-Blue

The Inspyre Evo-C Disk Junior 18.75"TT BMX Race Bike-Blue brings the same race-proven design to an even more compact, lightweight setup for younger riders. Built around the 6061-T6 aluminum Evo-C Disk frame, it features a carbon fork for precise handling, Forward hubs for quick engagement, and Tioga tires for smooth, confident laps. The Junior size is dialed for up-and-coming racers ready to build skills and speed on the track.

NOTE: As with any complete bike, J&R Bicycles recommends 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.
