Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Forcing the bike industry and cyclists in general to get over their obsession with weight over every other characteristic is actually an intentional and positive outcome of the UCI weight limit. At yet people still think that lighter is automatically better.

GCN interviewed someone involved in the regulations, Dimitris Katsanis, who discusses the minimum weight rule at 5:40 and again at 13:38:

You mean to tell me that no one wants disc brakes, gut they come in asking for bikes with discs because they been brainwashed by BB?

That's the way it works. Unfortunately, they got me before I lined the inside of my helmet with aluminum f- uh... with a Faraday cage... but now that I'm all set up, it's back to "good enough" on future purchases.

I'd use disks if I was doing a lot of riding in mud, but otherwise, I think it is a waste to use a disk when the rim can do the same job for no extra weight.

Hmm, why so much fuss about brakes.
When runway models win races, the real rub is what 'supplements' provide a technological advantage to the biology.

Sure, rim brakes are definitely as good for the standard schmoe like us. Except for in the wet. And mud. Oh, and descents.

If someone is concerned about the weight difference between disc and rim brakes, and their BMI (yes, I know BMI isn't perfect, but I need something for a comparison) isn't under, let's say a BMI under 20, I'd just suggest cutting off the extra slice of pizza.

It isn't just the weight - an elegant design gets at least two functions from as many parts as possible. As for the wet, aluminum rims and Mathauser shoes have always been fine for me, including descending the Sierras with 45 lbs of touring gear. For extreme slopes, either system needs extra mass. BTW, the highest generation of heat occurs when the speed of a free descent is halved by the brakes. Faster, and the air is helping, slower and the rate is lower.

the real issue will always be discs are just bad on road bikes , its a fact , road bikes operate at more specific points than other bikes , discs on off road bikes usually work because you want more locking power and rims just get weakened by dirt and sand , road bikes have higher frequency and when riding at higher speeds need an equal and even braking pressure discs can cause deflections in the wheel and throw a rider off, which is why we see so many more crashes in the TDF and world tour on descents , normal turns go from stable to wobbly nightmares because discs without abs are dangerous , you wouldn't want them on a motorbike or car , but people think a locking brake is somehow safe , NOPE , you will end up like Rem turd co flying over a stone wall to your doom , rims are also cheaper and allow a lower entry cost , so more people can ride , and as the industry trends towards discs we will see it hard for the poorer people ro afford the bikes , discs are harder to work on and require way too much effort for the average person whoo just isnt interested in tweaking their breaks all day long , it will be sad in 5 years when a rim brake wheel set no longer exists because everyone wants to buy the new shiney turd , so now we are all forced to ride these crappy components that cost twice as much , and present an even bigger problem , because a bunch of dentists wants to show off on the group ride

I think the above may have set a forum record for the longest run-on sentence.

You don't think that it was an admirable attempt to reach maximum nonsense density ("nonsensity")? One or two more "points" and that post might have collapsed upon itself creating a BF black hole.

Interesting calculation. You mean if the brakes are held on continuously? In other words suppose with no brakes you'd go down a given hill at 50kph. If you drag them on and descend the whole thing at 25kph that's the best way to cook them?

In practice the best way to keep the brakes cool is to brake as late as you dare for the corners because then you're getting as much use as possible out air resistance.

I'm a few planetary orbits below what would constitute an athletic cyclist and a couple of black holes removed from a your average professional racer, and I'm not even in the same galactic cluster as the likes of Chris Froome. My daily riders are almost exclusively a pair of Dahons these days. My "sporting" one is a Mu with good old-fashioned V-brakes; my "pothole crusher" is a late-model Hemingway, factory-equipped with what appear to be de-branded, bottom-of-the-parts-bin Avid mechanical calipers and levers (I figured that they might have been supplied by Avid because they run BB5 pads. My modern full-size hybrids - both with V-brakes) are up for sale; my gas-pipe steel classic is sitting in the balcony, completely disassembled, in search for a replacement frame with good dropouts that's actually my size for a change, but I've all but lost interest in that project altogether.

The Mu's V-brakes work well enough for what they are, how I ride the bike and where. I'm sure the disk brakes on the Hemingway can't hold a candle to even the most basic, entry-level hydraulic disk brakes, or any mechanical TRP, for that matter, but they, too, work well for the way I ride the Hemingway and what I do with it.

Point is, I enjoy each of the two bikes in a different way. That's my current N+1, where N = either one of these Dahons. It doesn't need any more thought put into it than that.

With that being said, while I might be a little curious as to how a possible future Mu or Speed with disk brakes would be like to ride, I can't say that I'm looking forward to the change. In fact, I'm inclined to think that there's a good chance that disk brakes might even ruin the experience. A Hemingway or a Launch with disk brakes might be better for it, but disk brakes could dull the nimble, lightweight feel of a Mu or a Speed. Or they could turn them into better bikes. We won't know for sure until actual Mus/Speeds are available to swing one's leg over. But I'd rather see the Mu/Speed range upgraded to D10 - or even D11 - levels with quality, reliable V-/caliper brakes than merely updating either or both D9's with unbranded, bargain-basement mechanical disk brakes.

This is an irrelevant, pointless, ranty post that's worth much less than ¢2, but here we are.

The decline of XC MTB Racing’s influence in mountain biking culture in the late 90s is the best thing that ever happened to mountain bike design and technology.

The world of Road riding would benefit greatly from the same.

The whole neutral support 15 second swap thing is relevant for less than 1% of people who own a road bike, and even for them it is only relevant a small fraction of the time they are riding (when they are actually in a race)

As far as Froomes arguments: if his brakes are constantly rubbing he needs a better mechanic. I can easily get mine not to rub. Overheating? Use a bigger rotor.

Derailleurs too, especially SRAM.

Chris Froome is entitled to his opinion, the rest of us are entitled to know from years of experience that he's wrong on this.

And this isn't the racing forum, so anxiety about neutral team support Italy relevant to most of us.
