I know it's just a way of expressing it, and you are surely fully aware of how it works. However, saying that aero "takes over" seems to imply that below a certain speed aerodynamics laws just don't hold and then all of a sudden, beep, they "wake up". Of course I know that you meant to say that aero becomes the predominant force against the cyclist. but I've found that people tend to misunderstand aerodynamics when they read posts like this - not necessarily here, but on other boards I've read plenty of time people saying stuff like "there's no aero benefit under xxx kmh".Hexsense wrote: ↑Thu Oct 25, 2018 7:47 pmRight,
With my previous 21mm internal width wheelset (28mm outside)
23c is 27.3mm wide
25c is 28.3mm wide
front wheel shouldn't be more than 25c clincher for best aero performance. Even 23c at 27.3mm is full two mm wider than what pro use (25c tubular at 25mm, they don't run oversize like modern clincher tires on wide rims).
Under around 30km/h your 32c, providing it is made thin and fast, will be faster due to better rolling resistance. But once aerodynamic take over at higher speed, you better use 25c front (and probably 28c rear). This is assumed your wheels are not 36mm wide externally or something crazy wide.
So yeah, it's just a personal crusade to make sure that people understand
