So can someone explain this Q factor thing to me please...
I've seen Xav posting stuff about the Limits PM where he seems to be saying that high Q leads to injury risk, but I also see lots of people mentioning Q in this thread which leads me to guess that there is an aero benefit. Perhaps narrow Q -> lower frontal area and less turbulent air between your legs and the frame, thus more aero?
I need new cranks for my TT bike... The cheapest option is to replace the chainrings on my existing Rival cranks (which are the correct length), but I also like the look of Rotor flow cranks, but then posts on the previous page appear to poo poo rotor for increasing Q...? Do I need to worry about Q and why?
