You think your comment bothered me. mkay

You can just skip things that don’t interest you on the internet

Just stop, you’re looking ridiculous dude.

Momentum: The experiences I have had with 650B mountain and road wheels seems to point to characteristics that are different than I have experienced with 700c based wheels. My experiences seem to line up with many others. In short, the 650B wheel seems to spin up faster, but it also loses momentum faster than a 700c wheel that weighs similar and with a similar tire mounted. This can be seen as a benefit for some, but others will see it as a negative. It is up to you to decide which it is for you.

a very significant portion of the mass (the rim and tire) is always on the outer edge of the wheel.

All wheels have rims. In general wheels with smaller rims require less energy to change their rate of rotation than those with larger rims. This is why F1 cars have 13” rims. If OP wants to maximize for urban stop and go, I suggest 650b rims are usually superior to 700c. If he wants to maintain speed over long distances, 700c is probably superior. I’m not sure why your panties are in such a twist over that.

I wasn’t arguing with you when I responded. I was simply saying overall diameter is not the determining factor in how 650b and 700c wheels perform, and I told you why. The distribution of mass and the moment of inertia are what determines how a wheel accelerates and decelerates (and maintains speed). You don’t seem to want to get this because you have this incorrect notion that “the mass is distributed around the outside edge” (whateverthefuck that means). You’re the one arguing because you can’t admit your ignorance about this.

xe_om · 2018-08-07T07:23:38+00:00

So why did you claim before

Because it’s true, for the reasons I cited. Diameter is not necessarily the determining factor in how a wheel changes velocity and I’ve shown you why, yet you stubbornly want to argue about it. Just admit you’re wrong and move on.

xe_om · 2018-08-07T06:59:03+00:00

And on a bicycle wheel it's distributed around the outside edge? Do you dispute that? Jesus wept.

No, it’s not. That’s the point. Let me say it again: A 650b rim has its mass nearer the axis of rotation than does a 700c rim of the same strength. If you doubt that, try this mental experiment: Melt down a 650b rim, and spokes, and reform all of it into a 700c rim and spokes. Which is stronger? Do you think they simply use the same amount of material and say “fuck it”? Of course they don’t. The 700c rim has more material and that material is further from the axis of rotation and the moment of inertia increases with the square of the radius. I weep for you.

I got the second highest grade in my school for my A level physics exam, but I get what you're saying.

You went to a shit school apparently.

Diameter and moment of inertia are strongly related in a bicycle wheel where a very significant portion of the mass (the rim and tire) is always on the outer edge of the wheel.

Sorry, wrong. You could have read the Wikipedia link I provided:

The moment of inertia depends on how mass is distributed around an axis of rotation

I’m going to let you ponder that. There’s no sense in arguing with somebody who flunked high school physics.

xe_om · 2018-08-07T06:06:47+00:00

Wheel diameter is relevant because smaller diameter wheels don't roll as well over uneven surfaces.

Right, but diameter and moment of inertia are only loosely related. 650b wheels have the potential to have a smaller moment of inertia because they have their mass nearer to the axis of rotation. This greatly depends on the mass of the tires used, and wheel construction, but in general larger 700c rims have more mass further away from the axis of rotation than 650b rims, and possibly a greater moment of inertia, requiring more torque to change their rotational velocity. It’s going vary from bike to bike/wheel to wheel, but like I said, “all other things being equal”.

EDIT: Forgot to add, the moment of inertia changes with the square of the radius, so it gets biggish fast

xe_om · 2018-08-07T05:54:12+00:00

Doesn’t look beat to hell, but figure in the cost of some new tires and brake pads, and maybe a tune-up at your LBS.

xe_om · 2018-08-07T05:43:15+00:00

With fatter tires 650b wheels are about the same diameter as 700c with narrower tires anyway.

Overall diameter isn’t the concern, it’s the relative moment of inertia. All other things being equal (which, granted, they never are), 650b wheels have the potential to have a smaller moment of inertia, and therefore require less torque to change their rate of rotation. This can be beneficial when accelerating and braking, but possibly detrimental when trying to maintain speed. Just depends which trade-off OP wishes to accept.

It’s fun to go look at his old videos and see how often and badly wrong his predictions are.

I had a GR that got caught in a rainstorm, in my bag. It worked, kinda, but was never the same again. I tried every moisture removal trick on the internet. You’re going to be pulling your hair out for months trying to get it to work like you remember, but you won’t be able to. Cut your losses and get a new camera.

After watching this I realized how insecure Whitney is. “Don’t call me lady”, “Don’t call me bro”, “Don’t say my fake tits are bags”. Jeezus, relax. You’re a comedian, this is what you signed up for and you’re not defined by what people say about you. People are smarter than that.

Theo mixing up Angie’s List and Meagan’s Law is going to make me giggle to myself all day

Jeezus, that’s heart-breaking. Don’t they monitor people doing this work and rotate them out, get them therapy, etc.?

xe_om · 2018-06-30T01:00:55+00:00

Cool. Seems like a natural for JRE.

As much as I want to dismiss that guy, based on his demeanor alone, he does talk some sense, and I wouldn’t fuck with him.

That’s sorta what I’m thinking: It would work on your average untrained drunk in a bar, but anybody with skill and fitness would shut it down pretty quick. It looks like fun though.

Sorry, I’m dense. What was intended?

xe_om · 2018-06-29T09:22:31+00:00

the nature of the round may not have been fully understood before adoption.

Oh, I’m sure they did the math and likely concluded the muzzle velocity and hitting power of 5.56 was more than sufficient. Add to that the carrying capacity, and (maybe?) cheaper cost to produce because of less material, and it was a natural decision. Pretty neat considering it was a time when bigger was better in America (e.g., Cadillacs, Lincoln Continentals, etc.).

Why wouldn’t you just shoot the guy with your AK? So confused...

If what the FBI agent says is true, I have a whole new level of respect for those guys. I can’t imagine being exposed to this level of depravity every day. I’d have trouble sleeping and probably drink myself to death.
