This is pretty much how I feel about it.
I’ve never said this before and I hope I never have to say it again. That is too much purple ano.

wart-fork and the light mount are giving me none-of-it
curly stays are cooool tho
What i’m loving is stumbling on some random dude’s DIY(2) homecar that checks so many of the Tarck boxes - in the land of nude beaches, no less!

Wonder if it’s got dynamo-backed charging for the di2 battery
reach numbers for 48,53,56: 385,383,384 
Yeah, my friend Zach made this chart for that model, not great.
Though what’s the actual point to reach when the STA angle is changing as much as it is on that machine?
? Not sure I follow your question.
The actual reach dims show that even though the changing STA makes it seem like the effective top tube is changing, in reality the different named sizes are more similar than different.
I have to figure this out. I charge my Di2 at the junction box.
aka Z factor aka Grant Peterson was again ahead of the curve
Reach doesn’t take into account any distance back of the vertical line from the BB. My emergency randonneuse (@73.5° STA) has a 432 reach, but it’s got almost the same ETT (±5mm) as the machine I made for a friend in North Carolina with a 382 reach (and a 71° STA.)
Stack at least tells me if I can get the handlebars down to a comfortable height. Reach doesn’t tell me whether I’m going to have a saddle under my butt (at least without doing horrible horrible things with offset seatposts.)
Isn’t this the point of that measurement? That you must always place your body in the same place regardless of whatever crazy thing the seat tube is doing?

Well, yes, but for me it’s in relation to the saddle, and then I expect the handlebars to be at a relatively fixed position forward of that point. A super slack ST (like the the machine that went to North Carolina) just meant that I could ride it with the handlebars jacked up to almost riv-approved heights without feeling like I was riding an omafiets.
Bodies don’t work that way though, because your hip angle determines how far forward your hands get — so the Reach of a frame is correctly determined from the BB, not the saddle
Saddles are also wildly inconsistent in layout, you can’t just measure from the nose or tail
The one real thing that’s fucked up about Reach is that it’s coupled to the Stack, so you have to normalize the stack values with virtual headset spacers to compare two frames of different heights

Yup. That’s why on a machine with a slacker STA I end up with a comfortable higher handlebar; my hip angle is remaining constant and I’m rotating backwards on the saddle to make my feet & hands line up with the crankset & handlebars.
