Great vid. While testing a non cycling device at the A2 wind tunnel in NC the technician gave me a freebie bit of aero TT advice. He said from what he's seen, the biggest and easiest aero gain is to simply squeeze your shoulders in as tight as you can. Reduce that frontal area and go faster. Makes perfect sense.

Thanks for sharing this, Ben, and thanks to Silca for helping make it happen. It is all quite fascinating, even for me, who typically doesn't care much about numbers and analytics! There is so much to consider, but the highlights to me are: 1) Aero is primarily of concern if folks are going 18 mph or higher. 2) when aero is of concern, bars (and resulting body position) will most likely matter more than wheel height/wheel depth. At Mid South, the elite of the elite are maintaining 23 mph average. Heck, I'll put you right up there with the elites when you can average 20 mph. But obviously the bulk of cyclists cannot maintain that speed, even if they try. So in my mind that means there are other considerations for them (let's just call it the vast group of riders that are riding 16 mph or slower) that take on the real priorities. My guess is that rider comfort becomes the most important factor for that vast group. Comfort results in the ability to maintain focus, stay on the bike for longer segments, less physical and mental strain, etc. All super fun to consider. I can imagine a 'Whats fastest for an elite rider vs what's fastest for a slower rider' test of some sort. Cheers and thanks again for sharing! -Mike

Very interesting! One thing that confuses people often: rotating mass. It only matters if you brake. If not, then the extra energy you spent bringing the deeper wheel up to speed stays and you get it back when you slow down (intertia). But if you're braking constantly then don't get deep wheels: MTB. It's why a bike with deep wheels can feel like it's steam rolling through ondulating terrain.

Excellent thanks Ben. The most interesting takeaway for me was that for a ‘normal’ gravel rider, someone who inevitably rides at below the 18mph (29kmh) aero speed / benefit threshold, headwind speed is still a major factor. Add 9mph (15kmh) riding speed to a 9mph headwind and you get to the 18mph aero benefit. …and that is not even a windy day.
Clearly aero is a thing, no matter how fast someone rides. …especially relevant, not in terms of winning anything at least in my case :), is that less wattage expended might also equal more than the sum of the parts. IE: less watts expended into a headwind in the first 2hrs of a gravel event is cumulative in terms of human endurance and power and might result in say, a 3-4hr time for the event, rather than a 5hr blowout! ...The exponential increase in aero benefit at higher speeds, presumably also equates to an exponential saving in energy expended over time at lower speeds into a headwind! …so aero is not just about going fast. For the majority of gravel riders it might also be about surviving the event in reasonable shape = more enjoyment, less pain! Cheers

About 7 or 8 years ago, i switched from the super light (at the time), Mavic climbing wheels, to Enve 4.5s. I then went and hammered my favorite downhill, one that I have the KOM on. Surprise, the Enve's were 4+ mph faster! Granted, my top speed was 52 mph. I never looked back. I then swapped bars a couple of years later from 44s (my shoulder width) to 40s. I was a little worried my breathing would suffer, but too my surprise, again, i could actually breathe better, i think, because i could stretch out further. Then i turned my levers inward a bit. This is a major comfort improvement, and if you haven't tried it, you should. It doesn't take a lot, maybe 5 degrees, but in addition to being more comfortable, you can, again, get even lower. All good!
