In what way does the absence of a seat post benefit the fresness of your legs? I do like the looks of the P3X, but haven't heard this argument before.
I understand there are limitations to such qualitative claims. :-)
The Hoff seems to believe itâsee around 1:37 in his report (YouTube below). And from my subjective POV, I agree with himâgranted, the impact is likely less than tire choice, but still with all that time in the saddle, the small differences accrue, I think.
https://www.youtube.com/watch?v=jtHAVX95S0E It really is a very different âfeelâ. The drivetrain and bottom bracket are ultra stiff with immediate transduction of torque to the wheels and zero flexâhowever I feel a slight âfloatâ feel on the saddle. I would not go as far as to say this is passive suspensionâit is hard to describe. I thought this might have been just in my head until I switched out my road bike (BMC Roadmachine One which has a conventional rear triangle) for my Cervelo P3X on my Wahoo Kickr for a long indoor workout. When rear hub is completely locked in, it is immediately apparent there is indeed slight flex with the seat. I went back and forth in this experiment, and it is indeed realâanyone can try this. Whether or not this actually translates into any additional âfreshnessâ coming off the bike is purely subjective and individualâI feel it, but fully admit this might be unconscious bias from having spent so much money on this thing. ;-)
