undersized road bike frame trend in professional ranks

14 Jun 2018 20:24

Been watching a lot of racing and what I am seeing is that most of the pros are running what appears to be at least 1 frame size too small with tall seat posts and long stems (>110).
I am perplexed by this. Am I imagining this?

Back in the day riders would often get the size smaller to save frame weight. But now weight is no longer an issue as it is easy to make a modern bike meet the UCI limit.

I always thought running an excessively long stem like 120+ would hurt bike handling characteristics.
Does anyone have insight on this trend?

Small frames are stiffer. Long seatposts=comfort

----------------
Or, full-sized carbon frame with moderate seatpost length would be too stiff / uncomfortable.
Small carbon frame is plenty stiff for power application, and long stem & seatpost enable desired position & comfort.

You are telling me there is a significant stiffness difference between say a 54 and 56 or 54 and 58 modern carbon frame?
