Without reasoning your claims are just unjustified opinion.
Seriously, you’re saying my opinion is “just unjustified opinion” then say things like “all the obvious reasoning would suggest it should be (by far) the more capabale”. Forget real world experience, what I need is obvious reasoning…
You can “should be” all you like, it’ll not become “is”. On paper it looked amazing, but in the metal it felt excessively high and front-endy, not all that stable despite being so long (which robs it of agility), and wallowy. Even in “long-and-low” mode it’s a little bit steep and tall (I’d liked to have tried a set of 66s in it but that’d make it even taller). Oh, and the frame design gives you a very limited range of seatpost movement, I needed a Scoper to get both a good pedalling and descending position, couldn’t be done with a standard post. And for whatever reason, it bobs like a duck.
To be fair, if I’d got one in 2005 it’d possibly have blown my mind. And it does fly superbly.
