The ird does look cool. I have an old sugino mountain crank that has the triple version of that and discovered that t.a. makes a 29 for the 94mm bcd. Pretty cool really. They also make a 33 for the 110. These are tiny differences but the placebo effect shouldnt be discounted. Not to mention the differences that are important are the percentage of change. Hence 34 to 30 may only be 3 gear inches, but its also over 10%. At least another gear on a road bike. Might be the gear you need.
