Eric: First let me say I am sorry to hear about the problem, but glad things worked out for you.
I do want to thank you for posting this. I have been experiencing a knocking in the front of my Big Apple shod bike when braking. I thought it was a problem with the brakes or fork and had been doing all sorts or readjustments to no avail. On reading your post, I took off the tire to see if perhaps my rim was cracked as well. It is not, but on replacing the rim, I noticed that the Schrader valve inner tube (I had a flat in a location where I could not locate a Presta valve inner tube big enough for the Big Apples so the bike shop I stopped at used a Schrader) reaches almost to the sides of the rim. I am going to try and pick up Presta inner tubes today. With luck they may remedy the problem.
