Here’s an interesting (kind of) observation I noted on the most recent meetup… My second fan (Honeywell turbo..brill) arrived in the week, so I had 2 fans blowing on me… I felt SOOOO much more comfortable, and was able to keep up higher watts for longer without becoming a floppy sweaty mess.
Reading into the science of it all, the fact that we are only 25% efficient means that for each 200w of power we make, we need to ‘remove’ 600w of heat. I for one ride ‘really hot’..i.e unless it’s sub zero temps, I wear barely anything on the bike when out and about. Thus it makes sense that performance/ability will drop off if you overheat.
The book ‘Bicycling science’ has a good chapter on this too. You really DO drop performance if you’re too hot or dehydrated.
Anyways…. just a thought to say that there’s no need to be a full on sweaty mess, and having decent fannage may add a few watts to your legs without even trying!!
