The model Flat Out 330 High Grip is distinguished by its slightly more compact diameter (330 mm instead of 340 mm) and its technical coating designed to provide maximum friction with racing gloves.
High Grip Technology: The specific coating (textured polyurethane or high density alcantara in serial) makes it possible to maintain a firm socket with less physical stress, thus reducing the cramps and the fatigue on the long sleeves.
Diameter 330 mm: This shorter format offers a brighter and more direct direction, preferred by KZ drivers (gearbox) or those seeking instant reactivity.
Ergonomic structure: Profiled branches for quick access to pallets (clutch or steering wheel brake) and a clear reading of the instrumentation.
The 105 mm in magnesium is a high competition room. This is not a basic setting, it is a specific solution for specific needs:
Maximum lever arm: With 105 mm, you drop the load outward to load the outer rear tire. It is the absolute weapon when the kart is sorely lacking on the turn out of turn.
System "2 screws": In a length of 105 mm, a one-screw tightening would be insufficient and would create an imbalance. The system to 2 screws Allows you to distribute the tightening force over the entire length of the ring, ensuring a perfect maintenance on the axle without creating a single voltage point.
Magnesium (mg): It offers valuable weight gain on non-suspended masses and thermal dissipation that stabilizes the pressure of your tires during long finals.
