An insight into the Profile Racing Z-Coaster...

The Z-Coaster is a proprietary hub to Profile. It essentially works as a spring/pawl cassette hub that can be disengaged into a freecoaster with varying slack options. Like all products from Profile, this hub is made in the USA at the Profile factory.

The Z-Coaster's Pawl is "Z" shaped to allow for engagement/disengagement by the center Slack-Cam Ring. This also allows for adjustable slack. The pawls and ratchet ring have a proprietary coating that offer smooth engagement. There are 48 points of engagement. All of the pawls engage simultaneously.

The Z-Coaster has an outer driver support bearing for the oversized driver mechanism. This bearing supports the driver from the outside.The Z-Coaster's freecoaster mechanism can only work if the jam nuts are fully tightened for optimum compression. Utility patents and design patents pending.
