I just purchased a new rear wheel set up from RAD MFG and i noticed my stock axle wont fit and its much to small. No where on the site does it say you need a diff axle to use there hubs. So I guess my question is where can i find a larger axle to fit this hub? or do you think they sent the wrong hub. Ill call my shop to make sure they ordered and make sure RAD sent out the correct shipment. Thanks in Advance.
