The Z Coaster® is a proprietary freecoaster style hub engineered, designed, & manufactured by Profile Racing. It essentially works as a spring/pawl cassette hub that can be disengaged into a freecoaster w/ varying slack options.
Highlights of the Z Coaster®:
- The Z Coaster®’s Pawl is “Z” shaped to allow for engagement/disengagement by the center Slack Cam Ring. This allows for adjustable slack by being able to switch cam rings. They're available in 20 deg, 33 deg, 45 deg, 60 deg, 75 deg, 90 deg, & 115 deg slack options. This means you can dial in the slack from less than 1/8 of a crank to a full 1/3 of a crank!
- 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 pawls & ratchet ring have a proprietary coating that offer smooth engagement.
There are 48 points of engagement: all pawls engage simultaneously. - Slack Options: 20/33/45 Degrees (45 degrees = 1/8 of a crank), 60 Degrees (1/6 of a crank), 75 Degrees (1/5 of a crank), 90 Degrees (1/4 of a crank), 115 Degrees (1/3 of a crank)
