The linkage mechanism includes a first link member that is pivotable with respect to the fixing member about a first axis and is pivotable with respect to the chain guide about a second axis that is positioned above the first axis when the fixing member is fixed to the bicycle frame. The biasing member is coaxially arranged around the second axis.
