That is just a gorgeous bike! The accents of the gold chain and the black chain rings really make it look great. I have seen this done with aluminum bikes where the parts were polished, and they look sharp. A guy on another forum that I subscribe to does this as a hobby and sells some of the bikes. Here is a
link to the forum thread. It's a fairly large thread (for this forum) and has lots and lots of photos of the different bikes he has polished.
