A bicycle frame component includes a yoke member 864, a driveside arm 862 fixed to the yoke member, and a pivot arm 860 coupled to the yoke member opposite the driveside arm. The pivot arm includes a first portion rotatably coupled to the yoke member with a first hinge and a second portion rotatably coupled to the first portion with a second hinge. The pivot arm extends along the driveside arm in a first position, and the pivot arm has a second position including the first portion extending along the driveside arm and the second portion rotated away from the driveside arm and interfacing with the first portion. A first primary wheel mount portion is disposed within the driveside arm, and a second primary wheel mount portion is disposed within the second portion of the pivot arm. The pivot arm substantially axially aligns the primary wheel mounts in the first position. |
