Abstract:
PROBLEM TO BE SOLVED: To make the wall thickness of a rim thinner and achieve desired light weight by optimally distributing tension in fastening spokes to a rim regardless of a symmetrical rim or an asymmetrical rim.SOLUTION: A rim 10 for bicycle comprises: a radial direction outer portion 12 constituted so as to be connected to a tire for a bicycle; and a radial direction inner portion 14 having a plurality of installing holes 16 for each spoke. The radial direction inner portion 14 includes sidewalls 14a, 14b on both sides and a bottom wall 14c on which the plurality of holes 16 are formed. The radial direction inner portion 14 has first curvature discontinuous portions 14d, 14e which divide at least one sidewall 14a, 14b from the bottom wall 14c. The bottom wall 14c is configured so as to house each insert 18 with a hole, which holds a spoke head, at least in a part of the holes 16.

PROBLEM TO BE SOLVED: To improve binding force between a first ring part and a second ring part in a rim for a bicycle.SOLUTION: The rim 26 for the bicycle includes: the first ring part 30; the second ring part 32; and a binding member 34. The second ring part 32 is disposed on an inner periphery of the first ring part 30 and bonded to the first ring part 30. The binding member 34 binds the first ring part 30 and the second ring part 32 together.

PROBLEM TO BE SOLVED: To provide a rim having a wing compensating local wave formation, a manufacturing method of the rim, and a bicycle wheel equipped with a tubeless tire improved in brake efficiency and airtightness by the rim. SOLUTION: The rim has a pair of wings 27, 28 formed of metal, annually molded of a molded member, closely joining both ends of a member, and connected at least one bridge 23. An axial distance between the wings 27, 28 at a joining portion 138 is larger than an axial distance between the wings 27, 28 at a part separated from the joining portion 138.

Abstract:
PROBLEM TO BE SOLVED: To facilitate replacement of spokes with a simple structure. SOLUTION: A bicycle hub includes an axle 31, a hub shell 32 and a plurality of fixing elements 33. The hub shell 32 rotatably disposed about the axle 31 with a plurality of fixing portions 41, 42 disposed at both ends. Each of the fixing elements 33 is removably coupled to the fixing portion of the hub shell and has a pair of spoke attachment structures to attach a pair of inner ends of a pair of the spokes 21 to the hub shell 32.
