Inspyre Evo Disk Junior 18.75"tt Bmx Race Bike-black
Description
The Inspyre Evo Disk Junior 18.75" BMX Race Bike is Inspyre's mid-range disc complete - 6061-T6 aluminum frame with disc-specific geometry, Forward Joyride cranks, Tioga Powerblock tires, and Inspyre Evo disc hubs front and rear. This is a step up from the Neo in every component category, built for riders competing regularly at club and regional level who want a disc setup without building one from parts.
Forward Joyride cranks are a meaningful spec choice: they're a proper 2-piece crank at this price point, not a basic 3-piece. Tioga Powerblock tires are what serious club racers run - fast rolling, predictable cornering, durable. The Inspyre Evo disc hub system provides reliable engagement with the instant response disc BMX racing demands.

Frequently Asked Questions
What's the difference between the Evo Disk and the Neo?
Component specification throughout. The Evo Disk uses Forward Joyride 2-piece cranks where the Neo uses a 3-piece alloy setup - 2-piece cranks are stiffer under sprint loads and lighter. The Evo Disk runs Tioga Powerblock tires (a legitimate race tire choice) and Inspyre Evo disc hubs for faster engagement. The Neo uses basic double-wall rims and a flip/flop hub. Same Inspyre frame geometry - different spec level that shows up at the gate and through technical sections.
