Bike Frame Thickness Survey - Please Reply!

AI Thread Summary
The discussion revolves around the thickness of bike frames, specifically focusing on the wall thickness and outside tube diameters. One participant mentions their BMX bike frame has a wall thickness of .049 inches and weighs over 8 pounds for a 20-inch bike, indicating it is quite robust. They suggest that standard bike frames typically have a wall thickness of .035 inches or less, with cheaper mountain bikes likely being thinner. Another contributor clarifies that the relevant measurements for attaching a bike alarm are the outside tube diameters, providing specific measurements for their frame: the top tube and down tube are 1.5 inches, the seat tube is 1 inch, and the downtubes in the rear triangle are 3/4 inch.

Thick as in the metal inside a frame? On my bike, a very thick street bike (stunt/bmx whatever you want to call it), it is .049 throughout. And that is thick! The frame weighs more than 8lbs (for a 20in bike) I would say your standard bike is .035 or less throughout, probably less for a cheap mountain bike.
 
He's attaching an alarm to one of the tubes of your frame, Matt. He doesn't care what the wall thicknesses are. He needs to know what the outside tube diameters are.
 
lol, ok that's what I thought originally, but I thought that information was easy to get.
My frame:
top tube and down tube are 1.5"
seat tube is 1"
downtubes (rear triangle) 3/4"
 

Thread 'The Human Cost of AI'

This week, I saw a documentary done by the French called Les sacrifiés de l'IA, which was presented by a Canadian show Enquête. If you understand French I recommend it. Very eye-opening. I found a similar documentary in English called The Human Cost of AI: Data workers in the Global South. There is also an interview with Milagros Miceli (appearing in both documentaries) on Youtube: I also found a powerpoint presentation by the economist Uma Rani (appearing in the French documentary), AI...

Thread 'Urgent: Physically repair - or bypass - power button on Asus laptop'

Asus Vivobook S14 flip. The power button is wrecked. Unable to turn it on AT ALL. We can get into how and why it got wrecked later, but suffice to say a kitchen knife was involved: These buttons do want to NOT come off, not like other lappies, where they can snap in and out. And they sure don't go back on. So, in the absence of a longer-term solution that might involve a replacement, is there any way I can activate the power button, like with a paperclip or wire or something? It looks...
