12/17 block in the mistaken belief I could push those gears up anything
It's surprising what you can do when you don't have a choice. For a while, I used a 57t Campag ring and a DuraAce MF-7400 6-speed block with the 16,17 and 18 sprockets removed to save weight. Bottom gear of 57/15 was actually a touch lower than the 53/14 fixed I use now, and I have a lot more weight to push up the hills these days.
