There is one thing that I don't particularly like about fat-tubed aluminum bikes. They are sounding boards for every creak, rattle, or knock. This makes any sound amplified and harder to track down. I'll get my Jekyll silent for a short while, then after a dusty ride it'll be a cocophony of noise once again.
Once again I picked up the phone and called down to the shop. I emailed them the pictures--the one above and another higher res version so that they could zoom in better than you--and started the warranty process.
