Well, since I chose a Tune crankset, I'll also choose a Tune seat clamp. The Tune Sattelspanner Sattelklemme Titan Ac 9 19 is very nice.
The small ring is a 20-tooth Blackspire that allows me to use an 11/27 cassette (a slightly modified 12/27 Dura-Ace).
I wanted to put all the rings in black, but my wife liked the black/titanium/black combination...just for once, she'd say, "I'll sell everything you have!"
And in addition to the Dura-Ace cassette, I also had two Dura-Ace 7700 chains, so it's a winning combination. I've used it on many bikes; it works very well.
The lower cable gland is the classic Shimano one, but I'll put a blue aluminum bolt on it. It's not visible; I could put any color on it, but it's a nice touch.
The crank bolts are SRP, also blue, of course.
