PRODUCT DETAILS
The Profile 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.
--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. --------------- Weights:
