Abstract
A bicycle front fork is disclosed, in which paired front fork assemblies capable of being elongated and contracted are coupled together at their upper ends by a cross member each lower end provided with an axle support for supporting an axle, the axle supports each having a support surface perpendicular to the axis of the axle. Each front fork assembly has a cross member holder having a mounting surface, which is perpendicular to the support surface of each axle support. The cross member is mounted by holding its outer surface in contact with the mounting surfaces and inserting mounting bolts in a direction parallel to the axle.
Claims3
A bicycle wheel fork assembly, comprising:
- a first inner tube slidably coupled to a first outer tube, wherein the first inner and outer tubes are capable of being elongated and contracted, the first outer tube having a lower portion with an axle support surface for supporting an axle having an axis perpendicular to the axle support surface;
- a second inner tube slidably coupled to a second outer tube, wherein the second inner and outer tubes are capable of being elongated and contracted, the second outer tube having a lower portion with an axle support surface for supporting an axle having an axis perpendicular to the axle support surface;
- a cross member coupled to an upper portion of the first and second outer tubes, the cross member having opposing side surfaces and opposing lower end portions, the upper portion of the first and second outer tubes each having a cross member holder with a mounting surface, the mounting surface substantially parallel to the axle support surfaces side surface of the cross member contacting the mounting surface of one of the cross member holders;
- a corresponding mounting member extending through each mounting surface of the cross member holder and into the side surface of the cross member to secure the cross member to the outer tube, wherein an axis of the mounting member is substantially parallel to the axis of the axle;
- and
- a brake mounting boss disposed on each of the opposing lower end portions of the cross member.
