Webers law is about perception of detecting a change, not the outcome or what happens to you mentally or physically if you do or do not notice a specific change. Our bodies and minds are not precision calibrated measuring instruments.

It also does not trump physics. I may or may not NOTICE an incline change from 0.0 to 0.1 but no matter, it will take more power and energy to maintain the same speed. On the flip side people actually do claim to notice the smallest things like the 30 gram weight difference between two different cassettes when the combined weight of them and the bike could be 180+ pounds and that 30 gram difference is a 0.037% change and claim it had an impact on their performance but yet they themselves could weigh 500 grams different one day over the next but they don't notice that?

I'm not arguing anything, I just don't believe some of what people claim to notice and if them noticing or not had any real impact. Same like the butt dyno related to a car performance. It is terribly inaccurate.

I can carry all I need for up to a 100 miles ride.

Are there any bikes being sold anymore with a pump peg?

Probably not. But of course it's often an option for custom built frames. Maybe "enthusiast" bikes. The pegs that clamp and screw on to your frame tube aren't usually preferred am I right?

Only some steel ones, but you don't need a peg with they type of pump. You do need a strap.

I hear the next expensive and unreliable product will be rubber bladders built into the frame tubes, with tiny hand-pumps (electric, for DI2 set-ups) and hoses which reach to the rider's mouth.

Water bottles aren't just uncool, they are un-aero. and the weight of bottles and cages? Outrageous. Trust me, before long all the cool kids will be riding bikes equipped with Tube-Sux® hydration systems. Options include the Little-Sucker® gel pump, and CO2 powered models ... because only a complete Dumbrowski would carry an uncool, an-aero, overweight hand pump.

If you can't fit it in your jersey pocket---stick it up your tube! Tube-Sux®, the original frame-contained hydration provider.

LOL

As if we were all competing in the TdF. I do what feels best for me, and I'd encourage everyone to do the same.

The other day I saw some bikepackers struggling up a mountain with more crap strapped to their bikes that definitely outweighed the bike by a factor of 2 or 3. Hey, whatever gets you up the hill, seemed to be working pretty darn well for them. They were enjoying themselves (I hope!), so that's really all that matters.

She's a woman, so why not a "fisherman?

.......

Shouldn't that bag be facing the other way?
(And... the one trimmed in red would look much better on that bike!)

Just another example of an over-sensitive, liberal, PC society we’re now dealing with.

Call me 'not bound by convention'.
Try it sometime, surprise yourself.

The velcro should not be impeding the cables like that. One of the bicycle peeves with those secondary marketed accessories.
