To clarify: for a given route, on one bike (a hybrid) I can average 17.5 mph and on this bike, it’s like 13.8 or something, and on one straight where I would be doing 20mph on one bike, on this one, it’s 16. And given the supposedly more aerodynamic position of this bike, you’d think it would be faster if anything.
So it’s absolutely nothing to do with “expectation”, as I’m comparing performance on the same route with different bikes – I didn’t make that clear…
