To provide a spoke for bicycle which can improve stability of rotation of a wheel, and a wheel for bicycle.SOLUTION: A spoke for bicycle includes a first end region on a side connected to a rim, a second end region on a side connected to a hub, and an intermediate region 11 positioned between the first end region and the second end region. In a cross section perpendicular to a longitudinal direction of the intermediate region 11, among straight lines crossing each other at two intersections on an outer edge 11A of the intermediate region 11, a distance between the intersections is the largest. When a first straight line 80 crossing at a first intersection 81 and a second intersection 82 is set, among two paths from the first intersection 81 to the second intersection 82 along the outer edge 11A, the first path 11B is longer than a second path 11C. The outer edge 11A has an outward protruding shape over the whole region.SELECTED DRAWING: Figure 6
【課題】ホイールの回転の安定性を向上させることが可能な自転車用スポークおよび自転車用ホイールを提供する。【解決手段】自転車用スポークは、リムに接続される側の第1端部領域と、ハブに接続される側の第2端部領域と、第1端部領域と第2端部領域との間に位置する中間領域11と、を備える。中間領域11の長手方向に垂直な断面において、中間領域11の外縁11Aに2つの交点で交差する直線のうち、交点間の距離が最も大きい、第1の交点81および第2の交点82で交差する第1の直線80を設定した場合に、外縁11Aに沿って第1の交点81から第2の交点82に至る2つの経路のうち、第1の経路11Bは第2の経路11Cよりも長い。外縁11Aは、全域にわたって外に凸である形状を有する。【選択図】図6
