Spitfire Formula Four Ishod 93D Lock-In Classics Wheels (54mm)

Spitfire Formula Four Ishod 93D Lock-In Classics Wheels (54mm)
Straight from Ishod Wair's own input, the Spitfire Ishod Wair Lock-In Classics bring pro-level design to Spitfire's Formula Four lineup. Cast in Spitfire's patented 93D Formula Four urethane, these wheels are built to be genuinely ride-anywhere — soft enough to smooth out rough ground, but formulated to still break loose and slide when you need it.

The asymmetrical shape is what sets these apart. The inside profile uses Spitfire's Lock-In shape, contoured to seat cleanly into ledges and rails for consistent, predictable grinds. The outside keeps the classic rounded Spitfire profile, so wallies and flatground tricks still feel familiar underfoot.

Available in 53mm, 54mm, and 55mm.
