Lightweight and rigid flat head screw made of titanium, with the optimum length for installation of 2-speed spur gears for more secure tightening.

Weight has been reduced by F:0.3g R:0.5g, removing this unnecessary material has improved rotational balance. Reduced clearance in the thrust direction helps maintain wheel stability during running.

Stainless steel material offers supple flex characteristics while adding extra weight for improved stability on high grip surfaces. This option part promotes mild steering characteristics.

Not only has rigidity been increased by using A7075, but the pivot height has been raised by 2mm compared to the standard part R300B/300H, providing more responsive steering and changing the camber change rate. To ensure clearance inside the wheel, the ball has been downsized from 8.5 to 8.0mm and the screw cap from 10 to 9mm and tilted by 10°. A specially prepared 8mm titanium ball is included to ensure proper steering angle. The main body is hard anodized.
