I have an all Ultegra 10 speed drive train, except for FSA cranks. I ran Ultegra chains for a couple of years, but then came across sale on Dura Ace 10 speed chains and decided to try it. No perceptible difference in performance or longevity, but noticeably quieter that Ultegra. Now I can't seem to find Dura Ace 10 speed chains anywhere. Perhaps Shimano has quit making them. Anyway, the Ultegra chain is a great chain and if you find it on sale get a couple.
Black is fine and all but it's fun to customize your bike w colored hoods! These are mfr parts so they fit your components perfectly. They take a little bit of work to massage on but they do the trick!
I love these brakes and I will always buy them for disc road bikes or cross bikes. The only thing that sucks is that they are a bit burly and if you press on the handlebars too hard whole you're mashing away the spokes may flex and hit the brake itself. Aside from that these brakes are easy to adjust and way better than the Hayes cx expert brakes I had.
