Michel's Council (Magickart): Release your engine!

"A fixed crown holder is often too rigid. If your alignment is not 100% perfect, the chain pulls on the engine and you lose power. My expert advice: The floating model HQ is a blessing, especially on demanding tracks like Alès. It allows the transmission to 'breathe'.

The essentials with your floating crown holder:

• Crowns CZ or AFAM: Use high quality crowns to avoid spoiling the accuracy of the floating system.

• Competition chain (CZ or DID) : A new chain on a floating crown holder is the ideal combo to win a freewheel.

• Chain and Lubricant Cleaner: The floating system must remain clean. If gum or dirt accumulates in the rings, it loses its efficiency.

A little pro secret: Check regularly that the floating casings are not gripped. The crown must be able to move slightly by hand. If it is blocked, a cleanup and a drop of fine oil are enough. At Magickart, all we can do is float on our racing chassis!"

Tuto: Assembly and Alignment

1. Tree cleaning: Spend a stroke of fine emery canvas on the 50mm tree before threading the crown holder to avoid any hard spot.

2. Installation: Position the crown holder in front of the box/engine output sprocket.

3. Lock: Press the locking screws symmetrically so as not to distort the hub.

4. Verification: Once the chain is laid, turn the tree empty. You will see the crown self-align. That's where you earn watts!
