Bicycle brake shoes are provided for a bicycle braking device. The brake shoes are pressed into contact with a bicycle wheel rim to apply a braking force thereto. The brake shoes are coupled to the bicycle braking device by brake shoe holders. Each brake shoe includes an attachment portion coupled to the brake shoe holder and a rim contacting portion for contacting the side braking surface of the rim. The brake shoes are formed from a polymer that is obtained by cross-linking Nitrile Buna Rubber, Styrene-butadiene rubber with sulfur. The brake shoe is elongated in the rotation direction of the wheel rim and has a braking surface opposite to the braked surface of the rim.
