| Suppose that's The Upright Bike Paradox: the more "comfy" you make a bike (further forward footrests, higher bars etc) the more weight you put on the bum, and the more comfy the seat needs to be. I had the beginnings of an aching bum on an ST4 myself, after not an enormous distance.
That's not to suggest that they're not more comfortable overall than a 748/996, of course. |
