Nice weather - very fast ride in....16.9 MPH rolling average, which is my fastest so far for the 21.5 mile ride in. With about 1 mile to go, my front derailleur stopped working. Cable slipped out, and couldn't shift the front. Also, when I got to the intersection before work, I noticed the front QR was open, and that scared me a bit. Locking it up in the garage, I tried to tighten the QR, and attempting to latch it, I heard a "crack.". Somehow, the thread for the cap nut got stripped, and wouldn't hook up.

I took the bike to Revolution Cycles in Clarendon (Arlington, VA) at lunch (Walking it onto the Metro), and they replaced the stripped cap nut and adjusted the QR. Also, they reseated the FR Der. cable, and adjusted it so that it shifted properly. 15 minutes, no charge. I was a happy guy!
