When racing always on F 42t and probably R 14t max - 28t. I Hardly use 11t and 12t.
So smallest, 22 x 28 =24" and 22 x 32 = 17, biggest = 78"
A 28t x 34 = 21" seems the way to go and fits in between the 28 and 32 on the 22T ring. As for smaller than 42T your choice, not gonna save much weight really though. TA makes rings this size I believe.
