Thanks for responses. And I just realized that the smaller ring has been swapped to a 38, so my bike is actually a 46/38, which explains a bit about why I found it reasonable to stay on that ring during a race and it felt a bit hard to pull steep hills. I think I should swap that down to a 36, and then get something like a 11-26 cassette on the road wheelset? Does that sound like a reasonable starting place for a road cogset combined with a 46/36 up front? I'm starting to grasp this all.
