On one bike I am playing with 46/28 and the Riv-spec'd 8 speed IRD 12-34. According to Sheldon that gives a range of 99.7 - 35.2 on the big ring. I am treating the small ring as a bailout - which comes in handy in Marin for the over 50 crowd. No issues on either ring across the cassette. Which is a nice change from using using a triple up front. And shifting to the small ring for a stop has been a good technique.
A couple of times I have thought that having 11 on the cassette would be nice - usually when I am spun out and a racer-type blows past pedaling strong. But it probably better to tuck at that point. Cranks are Suntour XCD with TA rings.
