This is a used rear axle and braking assembly replacement for a Bumbleride Era Single Stroller. Made between 2016 and 2025. Axle is straight. Brake and wheels quick release latches are fully functional. Will only with the bumbleride Era Stroller. Please check with me if you are not sure if this is the correct part for your stroller. To remove your existing rear axle assembly, you have to push in the two buttons on the two sides and nudge the axle out. Its a bit tricky to do.
