I'm using 44/30 chainrings and a 12-27 10-speed cassette on my 650B bike, giving me a 96 gear-inch high and a 29 gear-inch low. I spend most of the time in the 44 ring (cruising while in the middle of the cassette gets me around 70 gear-inches), while the smaller ring is used for climbing. This range works great for me. http://home.earthlink.net/~mike.sherman/shift.html?R0=30&R1=44&R2=999&C0=12&C1=13&C2=14&C3=15&C4=16&C5=17&C6=19&C7=21&C8=24&C9=27&C10=999&CAS=0&WI=13&CR=170&RT=1&ST=0&RPM=90&SRT=0&lRPM=80&hRMP=100&G=show&S=no&TITLE=&HL=1 Bob E.
