@clearcastle04, I've noticed that Vuelta sells 110BCD chainrings from 34t all the way up to 60t, so that might give you more versatility. I'm considering getting 175mm 110BCD cranks with two sets of chainrings: 56/42 (my current setup with the stock cranks) most of the time, and 52/36 or 52/34 for the occasional tour. Only their unramped/unpinned rings are available in such a large range of sizes, though. That's fine with me because I use the large chainring 99% of the time and only use the small one as a bailout gear on steep hills, so I don't need ultra-fast/smooth shifts.
