BOB Wheel Axle Assembly for rear polymer (black plastic) wheels (WH0500 and WH0501) found on all 2005-2015 BOB Strollers, except 2014-2015 Revolution PRO Strollers. Try removing damaged axle before ordering. If axle can't be removed then it is best to order the wheel which includes the axle already installed.
NOTE! This axle is NOT compatible with 2014-2015 Revolution PRO Strollers. Only option for axle replacement is to replace the entire 2014-2015 PRO Wheel.
