Personal preference isn't something you convince someone else of. We all like things someone else doesn't like. It's human nature.

So does Buell Motorcycles ..

I like rim brakes too and have no issue with them. But the above statement is false with regard to most disc brakes and doesn't need to continue to be thrown out as a reason.

I turn my disc brake bike upside down too. My hydraulic brakes don't care.

Interesting. That's handy to know, but it still gets told to me by disc brake aficionados, so I took it at face value.

I get burned many times too for taking things at face value that other people claim. Even by people that should know.

Look how long the idea that Otto Titzling was mistakenly credited for inventing the bra. Or maybe that is from a time before you were self aware, so it might not be a good example. If you weren't born before the mid seventies, you'll probably not have been party to it's heyday in the late 80's and even into the early part of this century.

Nope, not really consciously aware of things until '85 or so. However, if I'm to take "hydro discs work better in the rain" at face value from someone who uses them, I'll also tend to believe "don't turn the bike upside down" as well as "bed the pads properly" and other things pertinent.

Like I said, that's good to know, because I'll likely take the plunge myself for one bike this winter and wasn't looking forward to that restriction. But I don't feel foolish for internalizing it.

Lots of this bike isn’t to my taste, but some of the details are fascinating. The upside-down headset arrangement is obviously impractical but also very cool. I do wonder about how much load that pinch bolt crown is being subjected to, but it’s interesting. Those skinny seatstays, I don’t think I’ve ever seen anything like that in steel. Probably the only aesthetic element that really works for me; ok, the wheels are pretty, too. Yeah, the bit about “full diameter disc brakes” or whatever the exact words were is a worn-out canard rather than original, but it’s perfectly fine to point out that there are still reasons to build some bikes with rim brakes. He’s not trying to claim they’re just as good for pure stopping power, so I’m good with that. Finally, the seatmast is bonkers but it certainly brings some unity to the overall appearance. The saddle height and saddle to bar height seem very extreme for someone who’s only 5’9” but presumably he knows what he’s doing.

On the other hand - I do wonder, if this is what a 5’9” gentleman considers a “short” stem, what the heck is a long one? Plus the color really isn’t nice to my eyes. And those cranks seem like they might explode if you look at them harshly.

Bedding the pads (and rotors, actually) is a real thing. “Don’t turn the bike upside down” is baloney. Hydro systems are fully wet, and the system is airtight. There shouldn’t be anywhere for the fluid to go just because you turned the bike upside down.

for a recently bleed system maybe, but as time goes by there will be air build up in the master cylinder in the hoods. And the cylinder is designed to keep the air on top but if you flip the bike, the air will flow back into the lines

There is (can be?) air in the reservoirs of Shimano levers and it can work past the cylinder in to the brake lines, which is why the instruction manual (in an unintentionally comedic way) says that it will not brake properly when upside-down. Usually it's not problematic, but I have had soft/ineffective brakes after transporting my bike and it took a minute or so of vigorous lever flicking to work the bubbles back up and out of the lines.

Nothing of what you said (and especially the subsequent posters) addresses what I wrote. I did not, do not, and will not feel foolish for accepting the things disc brake users say about disc brakes. Maybe take a moment to think about why you have a hard time letting that go.

I was just trying to provide some information, guy.

Then check the aggressive tone, pal. You made your case previously and came back with "baloney" because you weren't happy with my response. But what else should I expect from "BOSTON BABY"?
