"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!"
Tree cleaning: Spend a stroke of fine emery canvas on the 50mm tree before threading the crown holder to avoid any hard spot.
Installation: Position the crown holder in front of the box/engine output sprocket.
Lock: Press the locking screws symmetrically so as not to distort the hub.
Verification: Once the chain is laid, turn the tree empty. You will see the crown self-align. That's where you earn watts!
Certified Performance: We select "HQ" versions (High Quality) for superior durability.
Expertise Transmission: A bad choice of crown holder can break a chain in the middle of the final. We're avoiding this stress.
Fast Delivery: In stock and ready to be shipped for your next test in the Occitan League.
