Abstract
A bottom bracket is connected to a spindle and a frame of a bicycle. The bottom bracket comprises a housing and an adapter. The housing is connected to the frame and comprises a substantially circular disc, one or more pins, and an actuating mechanism. The disc comprises a plurality of disc openings arranged proximate to a circumferential edge of the disc and is adapted to rotate with the spindle. The pins selectively engage with the disc openings, wherein the engagement of the pins with the disc openings prevents further rotation of the disc. The actuating mechanism selectively engages the pins with the disc openings. The adapter removably is attached to the housing and connected to the frame.
Claims15
A bottom bracket connected to a spindle and a frame of a bicycle, the bottom bracket comprising:
- a housing connected to the frame, the housing comprising:
- a substantially circular disc, the disc comprising:
- a plurality of disc openings arranged proximate to a circumferential edge of the disc, wherein the disc is adapted to rotate with the spindle;
- and
- a central opening adapted to engage with the spindle, wherein the central opening is defined by a plurality of indents for engaging with the spindle:
- one or more pins adapted to selectively engage with the disc openings, wherein the engagement of the one or more pins with the disc openings prevents further rotation of the disc and the spindle;
- and
- an actuating mechanism for selectively engaging the one or more pins with the disc openings;
- and
- an adapter removably attached to the housing and connected to the frame.
A bottom bracket connected to a spindle and a frame of a bicycle, the bottom bracket comprising:
