I install a SRAM X5 crankset on my homebrew cyclocross bike. At the recent Black Fly Challenge mountain bike race, the bike just didn’t have low enough gearing to make it up some of the steeper hills. So I decided to install a new crankset with smaller chainrings. This also involved adding spacers to the GXP bottom bracket since the new crankset is a mountain crankset. And I had to shorten the chain. I adjusted the Ultegra front derailleur as best I could, but I am ultimately going to replace it with a front derailleur made for smaller chainrings.
