Yes, 90rpm at lighter loads starts feeling stupid high and I want to upshift. I'm not talking about a hard sprint type situation. Just cruising along on the small ring and I want a burst of...

36x13 is 19.6mph at 90rpm. I'm starting to think about an upshift at 90rpm. Nothing worse than attempting to sprint and realizing you're out of gear.
