2023年の1/12世界選手権を記念した"Worlds"シリーズの第一弾です。
1/4インチサイズのリアシャフトに対応するスパーギア用の軽量ハブです。
スパーギア勘合部にOリング用の溝を配置しており、スパーギアの内径が大きくガタがある場合（キンブロー製など）にばらつきを吸収することができます。
Oリング取付時は、噛み込み防止のため、シリコンオイルを塗布して十分に潤滑してください。なお、スパーギアとのガタが無い場合はOリングの取り付けは不要です。
取付ビスによる重量バランスの悪化を抑えるため、カウンターウェイト形状になっています。ハブの重心はシャフト中心に一致します。
取付ビスとOリングを含めた重さはわずか1.9gです。スパーギア取付ビスはM3ですので、一般的なアルミやチタンビスを使い軽量に仕上げることもできます。シャフトへの取り付けはM2.5のスチールビスとなります。取付ビスの締め過ぎにご注意ください。
スパーギア取付のPCDは、市販の一般的なスパーギア（キンブロー、AXON等）に対応しています。
Oリングおよびシャフト取付用のM2.5ビスが付属します。

This component is the first in the "Worlds" series commemorating the 2023 1/12 World Championship.
A lightweight hub for spur gears compatible with 1/4 inch size rear shafts.
An O-ring groove is placed in the spur gear fitting part, and it is possible to absorb variations when the inner diameter of the spur gear is large (e.g. Kimbrough) and there is play.
When installing the O-ring, apply silicon oil and lubricate it sufficiently to prevent it from getting caught. In addition, if there is no play with the spur gear, it is not necessary to install the O-ring.
It has a counter weight shape for better weight balance. The center of gravity of the hub coincides with the center of the shaft.
The weight including mounting screws and O-ring is only 1.9g. The spur gear mounting screws are M3, so you can use general aluminum or titanium screws to make it lighter. Mounting to the shaft is M2.5 steel screws. Be careful not to over-tighten the mounting screws.

The PCD with spur gears is compatible with commercially available general spur gears (Kimbrough, AXON, etc.).
Comes with O-ring and M2.5 screws for shaft mounting.
