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.
Made 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 offers smooth engagement.
There are 48 points of engagement: all pawls engage simultaneously.
--The ZCoaster has an outer driver support bearing for the oversized driver mechanism. This bearing supports the driver from the outside.
***The ZCoaster's freecoaster mechanism can only work if the jam nuts are fully tightened for optimum compression.
Utility patents and design patents pending.
