Counting and estimation are different by definition. One is a full enumeration, the latter an extrapolation from sampled data. In both cases 'accuracy' is a factor. Even if we are counting the number of stars, it is still a differ

Gravel bikes with wide forks and MTB tires already exist. That was my point with the salsa cutty example. Classic gravel tires do not have very aggressive knobs, but there are some that do. Gravel is odd as that can be hard packed dirt, sma

TL;DR: (1) brain shape has not changed for about 160k years. (2) The framing/facts of the discussion is bad. Mutations are happening all the time, it is 'natural selection' that seemingly made lactose tolerance more prevalent

Lactose tolerance AFAIK is a single enzyme. That taking 6000 years to develop I think is evidence against what you are saying. Specifically, that is a tiny adaptation compared to the organization of the human brain. Is 30x more time than la

In 1800, there were 1B humans, 1950 is 2.5, 1990 is 5.0B, and we are now at 8.0B. I think we forget how many more people there are now compared to just 100 years ago. At -5000, there is an estimated 5M people. There's more than 1000x m

Rene herse has been doing those tests since 2006 "back when go-fast tires were 23mm." They covered a lot of variety and their conclusion is the aerial drag is tiny and real world conditions are more important than the idealized c

To break away requires you to put out 30% more power than the person behind you, and then also means you need to put out 30% more power than the rest of the field. That is a good recipe to go out hard, overcook, and then get passed up by th

Elite riders and teams are very conservative. They shift to new tech after it has been proven over decades. Consider that from a programming perspective, imagine using no tech newer than 2004. The transition to 28s took a long time itself &

You may want to look into dropper seat posts. They have road versions that are relatively stiff. Suspension weighs like 2 lbs (_very_ heavy) and can fail/needs maintenance, and for small bumps the shock absorber moving around loses a l

Salsa cut-throat is a gravel bike, fits 2 inch tires. Personally, I find having drops to be more comfortable because you can change hand position. Look to tour divide bikes for gravel bikes optimized for comfort and fatter tires. I don&#x2

Narrow will feel faster, and lighter accelerates faster - but the perception is often over perceived. So, the weight difference of 28 vs 42 is going to be 100g maybe. It's not a lot. Weight vs aero experiments have found conclusions li

You don't need aero bars to have you arms forward and narrow. It's not particularly safe, but doable for a while. The aero bar question (whether to have them or not) comes down to how long you will spend drafting and climbing. It&

From yet another perspective, one human lifetime of 100 years would see as much climate change as would normally be seen in 100,000 years.* Humans only started farming 12,000 years ago (which I still find shockingly recent), and humans used
