dann2707 Posted November 6, 2010 Report Share Posted November 6, 2010 You will need a bottom bracket tool. Remove the cranks at either side and simply fit the bottom bracket tool, attach a spanner or rachet of the correct size to the BB tool and undo. However I'm sure one of the sides the bottom bracket screws and unscrews the opposite way but you'll have to wait for someone to confirm that.
