Hi all, I've gone and lost the bolt on my rear axle of my 2012 Kona Operator. Before I drop £61 on a new axle does anyone know what size the bolt is or could possibly measure one on their bike? Unfortunately its not possible to just buy the bolt on its own. I am taking a guess I need to buy something like a 7mm flanged button head bolt?
