How uncommon is it to have a defective bottom bracket, a defective hub, a defective pedal, and a bent derailleur hanger on a new bike? I just had to have all of these either replaced or fixed and I've ridden the bike a total of 200 mi. since Feb. when I bought it. Oh, and before I'd ridden it for the first time I had to have the front brake replaced because a screw to adjust the brake pad wouldn't screw in. They gave me a new brake, which doesn't match the rear brake, but I'm told is better. Just wondering how big a deal this all is. I just wanna ride the bike but Jamis wouldn't replace the whole rear wheel, they told the owner of the shop to order a new hub which will now take a week to come in. Any thoughts, comments on my situation would be appreciated.
