This is a replacement axle for your Prodigy X Pro Scooter Decks. There are two different sizes, the 85mm being for the Prodigy X Street, and the 62.5mm being for the regular Prodigy X deck.
This axle is designed to fix perfectly with your Prodigy X Pro Scooter Deck. Compatibility with other decks is possible, but we can’t guarantee the fit.
