My rear wheel has developed a bad wobble, so bad that i couldnt even ride the bike anymore. I took it to a mechanic thinking it was the hub, and he said i just needed an adjustment. When he was done with the adjustment, there was still a wobble and he said it is because the spokes are damaged beyond repair. Do i just need to get a new wheel? or does all of this sound bogus to you guys? if I do need a new wheel, what are my best options? something that will last long. thanks in advance.
