I bought an aluminium Cannondale Touring bike back in '98. It was an
ST1000 from memeory. I found it uncomfortable. So I changed the seat, the
stem (two or three times), the handlebars (three or four times) , the seat
post, the pedals, the tyres, added mudguards (fenders), mudflaps and
If you narrow from a complicated system a single variable and measure it
with a selection of test items, you'll get data. Yes, a rigid frame's seat
post, saddle, wheel components and tires will contribute more to "comfort"
if you say vertical compliance equals comfort. What about lateral
I had a Trek Emonda SL6 (full carbon bike with a bontrager saddle that
looked like it would cut you in half and 25mm tires) for a few years and
that bike was super comfortable and really fast feeling, especially going
uphill. You wouldn't think that bike should have been as comfortable as it
I don't disagree with what he says but he could have been done in a minute
by stating the obvious: the up-and-down movement of your derriere is not
driven by the frame material since it turns out double diamond frames are
vertically stiff.
I'd recommend watching Jeff Jones demonstrate the
That guy in the video is a little annoying, but the information is spot
on! (One reason I don't really enjoy the handful of seat post Concept)
Old aluminum Cannondale's, Kleins and other Aluminum bikes were VERY stiff
and definitely would beat you up even with sloping top tubes and long seat

It's not exactly anything super controversial though. Basically all
frames have close to 0 vertical compliance by themselves before
factoring in seatposts, tires, etc. Totally checks
