Dang it. A couple weeks ago my front crank assembly was "knocking" and didn't feel right. Quickly took it in to LBS for fixing. They were suprised, said it had come loose and re-adjusted everything. Told me in no uncertain terms that if it started doing it again, immediately cease riding and bring it in again. So yesterday, same thing happened. So bike will go to shop on Thursday. I'm doing a part bus/part walk to work now. Not so bad, but today it is a beautiful day and I miss my bike. At the least it's still under warranty so the assembly should be replaced entirely.
