Solid axle for use in converting a Shimano quick-release rear hub to a solid-axle hub. Long enough for 130mm and 135mm spacings. Will work for other hub brands that incorporate cup-and-cone bearings and a 1mm thread pitch. Also useful in replacing solid Axle that have been damaged. Check thread pitch when replacing an existing solid axle. Take a nut from the solid axle you wish to replace. If the nut will thread onto a Shimano quick-release rear axle, then the solid axle the nut came from has 10mm threading. If the nut will not thread onto the quick-release rear axle, then the solid rear axle the nut came from has 3/8″ x 26tpi threading, which is slightly smaller and is incompatible.
