This is Seeker, Nightmare's big brother. He's making a big fuss over his little sister, and insisting she avoid more dangerous rides, whether due to terrain or neighborhood. "I'll drive to West Hollywood this weekend," he announced. "She's not experienced enough for traffic, and her tires are too new. My tires are in their last 15% anyway, so what if I hit some broken glass and we need to come home on the bus or whatever?" (Not the ones in the picture, he's running Maxxis Ikons now.) She says he's being a little patronizing, and she can take care of herself... but she does tremble a little bit when we mention street riding. And I don't think she minds the attention, actually.

This is Nightmare, a Grizl:ON CF 7. I've been blowing up my own thread with all kinds of observations about getting her dialed in right.

She is fast and very smart-- maybe a little too smart for her own good, like a lot of us at her age. Between riding the hoods and the vibration dampening from the front fork and CF frame, shockingly comfortable, particularly for my hands. Outstanding handling and better traction on these roads than any other bike I've ridden, I've yet to have the back end break away. I have to get used to how responsive she is, however. Takes a lot of focus over downhill 30 MPH. Have not had her over 35 yet.

Man, that's one classy-looking bike! Looks like a pretty happy dream to me.

I made this bike five years ago. The starter was on sale for $450. I have not ridden it much but since February I have been riding it daily because it is so comfortable as a town bike and with gravel tires it can go anywhere. It is super cheap to maintain. Now it has a MicroShift trigger shifter. It always has panniers and today I went shopping with it this morning for everything for a Wagyu burger lunch feast with a friend.

Just hit 37.8 MPH on a familiar downhill stretch with good visibility, leaving myself a large margin for error...

Which was a good thing. Brakes are NOT as powerful as the Seeker's, at least not from the drops.

Seeker has hit 38.9 on the same hill, but needed the entire hill to reach that speed. Even being on the drops, I have way less wind resistance on descents (I was also dressed more aerodynamically than usual). The increase in speed from about 33 to 38 seemed to happen very quickly.

I have found that a lightweight sweater boosts my aero-efficiency. You would think that that is counter intuitive. On the other hand it is bio-mimicry. Sharks have rough skin, birds that migrate over oceans between continents have feathers. The micro-turbulence makes you slick. I can take it down a power level against a head wind by slipping on a form-fitting light wool sweater.

Sounds like you've been smoking the wool... better stick to Vados before posting...
Then you can share you're insight with the Pentagon. 🙃

If the micro-turbulence was smaller as with cashmere, the drag would halve from Myth Busters'. Angora would be even better. She would aero slay me every time in that tight-knit sweater, Loretta. Jo-Jo, get back to where you once belong.

A dimple on a hard surface is vastly different than a wool sweater.
Show me a shaved sheep that's slower than his wooly brother and I might believe you

A shaved sheep has the about the same wind profile but is smaller, lighter weight, and less daggy. A goose or Albatross uses micro-turbulence to its advantage, just like dimples on a golf ball make it go twice as far. Idiot roadies shave their legs.
 
.... and then Google Ai doesn't lie.
"In sports where speed and aerodynamics are critical, like cycling, specially designed fabrics are used to reduce drag. These garments often feature:
Smooth, tight-fitting fabrics: These materials minimize surface friction and turbulence.
Strategically placed textured fabrics: These manipulate airflow to reduce drag, similar to the dimples on a golf ball.
Therefore, while wool offers excellent insulation and breathability, it's not the ideal choice when prioritizing aerodynamic performance. "

But the fact that you can actually feel the difference and use a lower power setting is the true

Then again.. a feather is not wool

Make two identical paper airplanes but on one lightly sand the upper frontal surface. See which flies furthest. Take a bike to a 5% long grade. Coast down in a T-shrit, then again with a sweater. What was the maximum speed?

This guy is so aerodynamic a few tail wags and he's off....

Let's see his modern smooth skinned cousins do that!
