Or, it could just be that in the days of level top tubes, smaller
diameter tubes were used to build bicycles, resulting in more flexible
frames than would be the case with oversize tubing of the same
thickness. And more flexible frames indeed can climb better.

Clearly, the up sloping top tube is making your climbs effectively
steeper. That's why it's more difficult :)

I'm trying to discern if there's any real (not imagined) physical
properties of the upsloping top tube on my 2009 Sam that would
make it a sluggish climber. I've never cared for the aesthetics of
the sloped frame, so I'm thinking it could be in my head. But the
truth is, I've always felt the bike is sluggish climbing, and I'm
curious what other's think. Granted, tires make a big difference,
but regardless of tires and tire pressures (I've used many
variants), the result is the same for me: sluggish climbing.
Whatever you do, please don't tell me it's the motor!
