The ZCoaster™ 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.
Made here in the USA at the Profile factory.

Highlights of the ZCoaster™:

--The ZCoaster™'s Pawl is "Z" shaped to allow for engagement/disengagement by the center Slack-Cam Ring. This also allows for adjustable slack. See Slack-Cam Ring options A through C.

--The ZCoaster™'s pawls and ratchet ring have a proprietary coating that offer smooth engagement.
There are 48 points of engagement: all pawls engage simultaneously.
