as long as we're at it, here's the gear chart for Doug's suggestion - Very useful gear set with no cliffs anywhere, hill climbers on every chainring, and narrow 50s/60s, where we spend most of our time. Chainline at the extremes might be tough, but the Microshift derailleur looks like it has the wrap to easily handle the chain length. I was excited to see Grant pick up that derailleur - their barcons (on my daughter's bike) are wonderful.
