BICYCLE BOTTOM BRACKET ASSEMBLY |
| 摘要 |
A bicycle bottom bracket assembly having a rotational central axis includes a support member, a bearing unit and a radially inward force reducing structure. The support member includes a hanger mounting portion and a bearing mounting portion. The bearing mounting portion is configured to be at least partly positioned within a hanger part of a bicycle frame. The bearing unit includes an outer race, an inner race and at least one roller element disposed between the outer and inner races in a radial direction with respect to the rotational central axis. The outer race is fixed to the bearing mounting portion of the support member. The radially inward force reducing structure reduces a radially inward force being transmitted to the bearing unit. |

1. A bicycle bottom bracket assembly having a rotational central axis, the bicycle bottom bracket comprising:
a support member including a hanger mounting portion and a bearing mounting portion, the bearing mounting portion being configured to be at least partly positioned within a hanger part of a bicycle frame; a bearing unit including an outer race, an inner race and at least one roller element disposed between the outer and inner races in a radial direction with respect to the rotational central axis, the outer race being fixed to the bearing mounting portion of the first support member, and a radially inward force reducing structure for reducing a radially inward force being transmitted to the bearing unit, the radially inward force reducing structure being configured to be disposed radially outward of the outer race with respect to the rotational center axis. |
