Hi Everyone, new to the form. Have a question about my front wheel center hub. When I was storing and cleaning the bike for the winter I noticed small hair line cracks. The cracks don't seem to be through the hub only close to the spokes. They are on both sides where the spokes are riveted to the center hub. Has anyone seen the same, should I replace the center hub (searched for a new rim, don't make them for our bike) or is this a normal wear and tear condition. Any help or advice grateful.
