Man, glad I don't have to deal with any of that BS!

If, as is the real world case, the argument on disc v rim brakes on bicycles has already been decided (by manufacturing and marketing), and you disc brakes, why start this thread at all ?

Or more briefly, as I stated earlier:

There really is an answer to this question, it's just not the one you seem to envision.

All my bikes have rim brakes. If you have disc brakes, you have better brakes than I do.

Not every one....and the whole disc and wheel retention thing is why the current standard for disc brakes is thru axle

I'm always amused by people who respond to "disc brakes are better" with "I've never had any problems with rim brakes", as if that makes them the pinnacle of bicycle braking technology. A couple years ago, I got a couple old (early 80s) bikes, with old single-pivot brakes. I found they were A LOT less capable than modern dual pivots, and I posted a thread on C&V about it. Of course I got a lot of useful suggestions, like getting some modern pads. But then there were the folks who said they had "never had a problem" with those old brakes.

I imagine lots of people who've never experienced something better than what they have, have "never had a problem" with whatever it is. In cars, most people "never had a problem" with drum brakes all around because most people weren't pushing them to their limits. In fact they might not even notice the improvement disc brakes in cars made because the car stopped regardless.

Anyhow, my point is that, in my experience with bikes with a variety of brake types, discs > dual pivots > late '80s single pivots > early '80s single pivots. That said, I ride bikes with each of those braking systems and have a great time doing so, and isn't that the point? If it isn't, why the hell would we even ride?

Manufactures started putting lawyer lips on bicycles long before disk brakes showed up on the seen. Obviously the QR setup was to complicated for some people. To add sauce to the goose the manufactures then made sub standard QR skewers for those lawyer Lipped bicycles. It is no wonder to me why some people claim that disk brakes can cause the front wheel to be pushed out. I believe that the disk brake equipped bicycles that had a wheel come out had help from functionally illiterate people.

Lawyer lips. You're thankful for lawyer lips? Man, I Dremel them $#it$ off and trust myself to tighten the QR sufficiently.

My rim brakes feel the same as the disc brakes I've ridden. I only ride when it's dry out. So what, exactly, am I missing?

that is a motorcycle, not a bike....pedals or not and even more so if it has a throttle, not just pedal assist

...I was trying to go with the theme here, that disc brakes are great. It's hard for me to find stuff that supports them as the standard on bicycles, given my use patterns. I'm trying hard here to be positive. Certainly they have enabled this whole expansion into the world of small, lightweight motorized cycles pretending to be bicycles.

Stopping that much mass, rolling at speed, would be a challenge for rim brakes.

For real? I haven't seen a factory fork dropout without a safety tab for many years.

Why start the thread at all?
- to try and understand why others wont get on board with what you think is clearly the obviously best choice.
- to try and convince holdouts, through conversation, that they should jump on board.
- to try and start an argument for entertainment.

I dont know why koyote started the thread as it isnt my week to peek into his mind and explain his motivations. My week starts March 17th, so ask me then and I can give you a more accurate answer.

Well, guy, I don't know what to tell you, except I find the disc brakes both more powerful and more capable of subtle modulation of speed than rim brakes, plus they work better in the wet.

Exactly. There are two dominant forces in the bike industry: the need to turn over customer inventory, and legal butt covering. The former is created by planned obsolescence, the proliferation of new 'standards', and choking off the supply chain for older parts. The latter results in dumb stuff like thru axles.

History:
  1. Campagnolo develops the QR in the 30's - a significant improvement that allows wheel changes in the seconds. You flip the lever and the wheel drops out.
  2. Some dumbass in some litigious country hurts themselves, and through the efforts of an ambulance chasing lawyer and muddle-headed jury, successfully sues. Hence: "lawyer lips". Now bike users have to tediously twiddle with their QR lever, actually increasing the chance of a retention problem. As in a lot of riders now just spin their QR lever and never clamp it down, as is necessary to get adequate retention.
  3. Next solution: the thru axle! It is not actually an axle, so it doesn't support any forces and it doesn't make anything stiffer or stronger. It is merely a wheel retention device, that features less clamping force than a properly applied QR. But it is relatively idiotproof, and allows the bike industry to shed any liability.

So now instead of the efficiency of the original QR, we have this heavy, fussy solution that requires spinning and fiddling. Plus it gets lost in your car or the trailhead, and costs $40 to replace. If you can find one of the 10 different 'standards' that fits your hub and fork.

Again with the "10 different standards". Hey, can I use the QR from my 6 speed bike with 126mm spacing on my 10 speed bike with 130? Or my hybrid with 135? No? Gosh, sounds like there are different, incompatible standards for QRs, too!
