Everybody here is somewhat right and somewhat wrong. Materials within any particular category run the full gambit from very long lasting to lasting long enough for the check to clear. Quality of materials and manufacturing processes are the big determining factors on longevity. All materials have their limitations and strong points. Design and manufacturing can make or break any material selection. All long time bike manufactures have designed and made some lemons. Generalities are worthless.

You generally pay for what you get but not always. A $5,000 bike will very likely last longer than a $179.95 Wal Mart bike.

You've stumbled in the bike version of Mac v PC, Republican v Democrat, Ohio State v Michigan we're just rehashing the same arguments we've been having for decades.

All my bikes are rim brake. But the premise that the bike industry changed to disc to sell more bikes is ridiculous. Every industry employs new technology that is typically embraced by many and rejected by few.

Auto keyless entry is great, but if you do water sports it is a royal pain. No one is going to take a fob along and paddle out. Thankfully I have a chip key.

Death Rides a Pale Cow. R.I.P. Dave Blood. I saw them play at a frat before they released their first album in Ď85.

Saw Electric Love Muffin at the same frat and some DJ named Jazzy Jeff (before he became famous).

Those were the days.

Wet fobs are a thing of the past when stowed in a waterproof case/bag that is attached to a QDC lanyard. That modern keyless entry tech just created jobs for another market...

I agree that the industry changing to disc brakes was not to sell more bikes. In any industry the more of any one thing you make, causes the price to go down because of economies of scale. They saw the demand for a better braking system, and they responded. It is now cheaper for them to sell all disc brake bikes than it is to sell both rim brakes and disc brakes. Pure and simple.

Of course that's ridiculous. Rather, the bike industry sold in the whole wide rim, fat tire thing, leading to selling more disc brakes.

Past 6 years since I've joined the Bike Forums, could always tell we are in middle of winter. Not by looking out the window, or seeing my bike on the trainer, but by the same arguments over every winter.

It's hilarious, each time, it started out with one thought and balloons into many different subjects.

Very entertaining! Thanks all!

Lol! At least itís not a knock down drag out battle over Rene Herse. Maybe we can do that next month, before temps start to rise.

Isn't the goal of employing new technology that will be embraced by many to sell more product?

The goal of any business is to make money; i.e profit. Developing and selling new products are designed by nature to generate more sales and more profit and ultimately market share along the way.

The Suntour vs Shimano saga of the late 80’s and 90’s was an example of new products that were embraced by the consumer and resulted in profitable product lines and the demise of Suntour as a competitor.

This market share allowed for such developments as rapid rise rear derailleurs. These were not well received by consumers and the evidence is a Shimano product design that has been completely ignored by third party manufactures. If there were any redeeming qualities Microshift or others would have incorporated that design.

So yes while it is the goal, embracing that technology is another question. If disc brakes were in the same category as rapid rise derailleurs, people would dismiss disc brakes and continue to use rim brakes, in the same way as top normal rear derailleurs, and the people at Mavic would be dancing in the streets.

137 posts and still no link to the "honest opinion piece" that inspired this thread? Hmm ... I just remembered, I recently read a really truly absolutely positively so-help-me-god objective article that states:

Every single racer on the world tour, except Chris Froome, thinks rim brakes are for poopy heads.
That should settle it ...

Totally agree. Where/how I ride, rim brakes are fine for my road bikes. My road rides are mostly flat and relatively dry, so I don't personally see the advantage. However, they are indispensable on my mountain bike.

I didn't read all 6 pages of this thread (apologies in advance) but I'll add one reason to the 'plus' column for disc brakes.
Specifically for those of us who aren't pros or otherwise sponsored with free new wheels/bikes/components (aka 97% of those on BF) and those of us who don't have the sort of disposable income to replace or otherwise buy new wheels on a regular basis. Disc brakes are great because the wear & tear is between the pad and rotor, not the rim. I realize replacing disc pads and rotors isn't free, but it's a hell of a lot more cost effective (and easier) than replacing a worn out rim. Especially if one likes to ride fancy carbon wheels.

Agreed. After 55 years of riding, moved to thru and discs at age 67, now 72, will never go back. They are just that good whether hydraulic or mechanical. MHO

I have several bikes with Campy rim brakes, one from the 70's and one that is about 10 years old. Aluminum rims on bike from 70's, Zipp carbon on newer bike. All tuned up properly they work very very well except for the carbon wheels in the rain. At that point the braking effectiveness goes way way down. About 3 years ago I was making twisty steepish descent (14%) in heavy rain and got pretty spooked when I started to accelerate on the descent. Despite pulling on the brake levers so hard I was sure I was going to break a cable or the lever, I sped up from only 13-14 mph to over 20 which doesn't sound like much but the fact I was accelerating and not decelerating made me sure at the time I was going down. Managed to keep my line for the turn at the bottom of the hill and got it back under control when the hill started to go back up. Whew.

The next year I purchased a Giant Defy Advanced with cable operated disk brakes. Incredible improvement over the Campy brakes and this is with a relatively cheap set of disks brakes. My mountain bike with hydraulic disks is even better, by a lot.
I've ridden (and raced a bit back in the day) for 50 years and with the exception of the scary rain incident, caliper brakes have served me well. However, there is no question in my mind that disks are simply superior and I would never buy a new bike without them. YMMV

Very true. Whole disc brakes systems can be bought for less than $100. CF rims alone seem to sell for around $350. Then there is the cost of rebuilding the wheel set.

I recall seeing as a kid a front wheel brake on easy going town bikes that was a rubber pad pressing on the tire from above, like in this picture of bike made in 1900. But it was not anything antique like this one, also the mechanism was 'more modern' than this, it was still made in 1960s in Europe. Talk about easy maintenance, adjustability, in my books that beats any rim or disk brake anyday. I bet you that is still used in rural China today.

Some people will argue it is superior to both disc brakes and rim brakes, because the diameter is bigger.

Honest opinion piece on disc brakes

I ride a Thorn Mercury with a Rohloff hub and Thorn supplied this bike with a BB7 disc brake on the rear so as to not have to re-rim the Rohloff too frequently and on the front I have an XT V brake (rim brake.)

Much is said about far better modulation with a disc brake which may well be the case with hydros but I find the modulation easier on my front V brake than on the rear BB7.

At my age (1942 model) I am unlikely to ever go back to a derailleur bike but if I did it would be with electronic shifting, it is a no brainer but last time I looked it seemed about 20% more expensive than a Rohloff.
