Description

図示の実施形態において、フレームロック１６２が係合されると、ピボット１５６は実質的に不動化される。いくつかの実施形態において、ボトムブラケットシェル１２６内の支承表面３０８および３１０を不動化するために留め具が用いられるスプリットカラーとして中央円筒状孔３０４を実装し、ピボットの回転を防止することができる。あるいは、中央円筒状孔３０４を通して、および円筒状スリーブ３０６を通して止めねじまたは他の留め具を受容してピボット１５６を乗車状態に固定することができる。 In the illustrated embodiment, when the frame lock 162 is engaged, the pivot 156 is substantially immobile. In some embodiments, a central cylindrical hole 304 can be implemented as a split collar in which fasteners are used to immobilize the bearing surfaces 308 and 310 within the bottom bracket shell 126 to prevent pivot rotation. Alternatively, the pivot 156 can be secured in the riding state by receiving a set screw or other fastener through the central cylindrical hole 304 and through the cylindrical sleeve 306.
