摘要:
A bicycle rim basically includes a first annular side surface portion, a second annular side surface portion, an annular connecting portion and an outermost layer. The first annular side surface portion includes a first braking surface. The second annular side surface portion includes a second braking surface. The epoxy resin layer is an example of a nonmetallic layer. The annular connecting portion connects the first and second annular side surface portions. The soft additive granules are disposed in at least one of the first and second annular side surface portions. The epoxy resin layer is disposed in at least one of the first and second annular side surface portions. The soft additive granules are at least partially embedded in the epoxy resin layer. The outermost layer covers the epoxy resin layer and the soft additive granules.
