Inspyre Evo Disk Pro XL 21.25"TT BMX Race Bike-Grey

Designed for serious track competitors, the Inspyre Evo Disk Pro XL 21.25"TT BMX Race Bike-Grey pairs a rigid 6061-T6 aluminum frame with a 21.25" top tube for riders seeking maximum leverage and control. The Evo Disk geometry delivers the structural integrity and responsiveness needed to translate power efficiently through technical sections. Forward Joyride cranks, Tioga Powerblock tires, and Inspyre Evo hubs form a cohesive drivetrain and rolling package engineered for consistent acceleration and predictable braking modulation. Finished in understated grey, this race-focused build eliminates distractions and prioritizes the mechanical advantage that separates winners from the field. 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.
