I've got Shimano 105 5700 172.5mm in black, which you can have for whatever they cost me. They've only done about 10 miles tops, but are 53/39.
Alternatively, I've also got 105 5600 172.5mm cranks on my road bike that you can have for way less. They're 50/34, but have done a good 2000 miles or so, but are silver.

Pm if interested.
