Ser um cara "mão na roda" parece ser tarefa fácil para qualquer um. E é, se você não for um acrobata.

As manobras em bicicleta são muito divertidas... de se ver e complicadíssimas de se realizar, por isso os dois Edus explicam um pouco sobre duas modalidades: o Bike Trial e o Flatland.

Steps to follow along with the Profile Z-Coaster Slack-Cam Ring Removal/Installation:

1. Remove drive-side jam nut.
2. Remove driver from axle (Bearing may be attached to driver, which is ok).
3. Use small screwdriver and begin to unwind spiral retaining ring. Use your hand to continue unscrewing the retainer ring off the driver.
4. Remove Flat Spring Spacer from driver.
5. Remove existing Slack-Cam Ring.
6. Replace with desired Slack-Cam Ring (***Be sure to have the laser etched side of the ring facing outwards. It will not work if it's inserted upside down).
7. Re-install Spiral Retaining Ring (Snap Ring). This can be done by screwing it back into its retaining slot by hand. But we strongly suggest using the Z-Coaster Snap Ring Installation Tool.
The tool makes installation extremely easy and prevents any damage to the spiral ring.
8. Re-Install Flat Spring Spacer (***Be sure Flat Spring Tab is in desired Slack Setting Slot).
9. Depress the three pawls with your fingers. Rotate Slack-Cam Ring counter clock wise to lock pawls in down position.
10. Make sure Driver Support Bearing is either on the driver or in the hub shell.
11. Now you can re-install the driver into the Z-Coaster by hand.
12. Install and re-tighten jam nuts (***Jam nuts MUST be tightened for Z-Coaster mechanism to work)
13.Go Ride!
