Most of the time, maybe.
Brake performace (modulation) and tyre grip can't be de-coupled. Tyres will give up grip when there is a spike in force e.g. when a wet rim brake 'decides' that it's going to grab.
I would think the most relevant racing situation is descending in the wet, where we always see riders wiping out whilst other riders carrying on around the same bend without issue.
I have a similar view having very powerful, easy to use brakes is useless if they are not consistent and don't have a good level of feel / control. All those reasons together are why disc brakes give a benefit. They allow you to brake hard holding the bike closer to the point you lose traction than rim brakes.
In mountain biking this is much more apparent due to the more stop, start nature of riding and relying on handling skills much more.0 -
Mountain biking. That sport where "rad" is a legitimate word and helmet visors are de rigour?
Pfffft. Jog on.0 -
We don't always see riders crashing in the wet. If you lose a wheel in the wet, you might fall off, you might not. The type of brakes is irrelevant. As it is currently, tyre grip is the main factor that will dictate the wheel slipping, especially in the wet. Disc brakes don't improve grip.
Most pro riders don't have problems in the wet and most pro riders seem to be against disc brakes.
I've got dura ace brakes and they stop me fine, in the dry and the wet. They are powerful, easy to use and consistent.
there is no comparison between mountain biking and road racing.0 -

Good point. You're right, we should disregard all experience from this arena.0 -

Glad you've seen the light.

It was just an innocent slip. I was too busy thinking about 'rad air' and such.0 -

Except the ones who fall off.
It is possible to lose grip in the wet due only to lean angle but in many crashes the rider is braking at the time too, so braking performance is clearly relevant to loss of grip. Control and modulation are clearly superior on a disc setup.
The discussion over discs was boring a while back and doesn't seem to be improving. Discs are clearly better brakes but still people fail to either admit it, value it, or need it. Only the last point has any real merit.Facts are meaningless, you can use facts to prove anything that's remotely true! - Homer0 -
It's because, like most things in life, there are pros and cons, it's rarely a straight choice between one or the other and when the choice is mixed people will tend to stick with what they have now.
If it was the other way around and they all had discs and the suggestion was to try the brand new rim brakes because they're safer there would be the same protestations I'm sure.0 -

Full Hydro discs may be better - cable and semi hydro are not clearly better and if you frequent the road buying and other sections of this forum you'll see lots of people who have fallen for the BikeRadar reviews of these brakes and have been unimpressed with the performance.[Castle Donington Ladies FC - going up in '22]0 -
Except that chain rings are generally covered by a chain, and there's no energy in them, because of the freewheel. Similarly for the sprockets, protected by the frame and will stop unless the rider continues to pedal.markhewitt1978 wrote:I think it's one of those things that we accept what is there now. If exposed chainrings were being brought in now there would likely be an outcry about having 'saw blades' on every bike.
The discs are another matter, particularly on the front which can be aimed.
ISTM that brakes in road racing really aren't something to be concerned about. Even in road biking in general. Long distance riding, commuting, riding in mud and dirt, makes sense not to use the rim as a wearing component. But in general it just doesn't seem to be an issue. Even on cheap Chinese carbon in the Alps.
More interesting road bike brake innovation is direct mount calipers and integrating the brakes into the forks for an aero advantage. Much more racy.

...except there have been some bad injuries from chainrings. The chain doesn't always stay on in a crash. Agreed, the cassette isn't much of a issue.0 -
Chain and cassette are also exposed but without them these is no drivetrain
Discs are something pro's did not ask and needed and its more dangerous compared to other parts0 -

Or maybe we just know how to set rim brakes up correctly which is why we don't see that discs are any great advance !
It's not just me that doesn't share this love of discs there are lots of people on these forums who just haven't found them that great.[Castle Donington Ladies FC - going up in '22]0 -
merida spokesman states his riders wanted disks.

Although, Kleinstocker has pissed his patent rights up the wall by publicly disclosing prior to filing for a patent. (I once nailed a famous golfer's dad on this once - which I wouldn't have done if he hadn't named his son with the same name)Twitter: @RichN950 -

It's hard to see how really, but I came off as as young lad and put a gash across my left knee which needed 7 stitches. I didn't notice it intially until I had sat up and my fingers went into the hole in my knee. Weird, it really didn't hurt until that point.
Yeah, but that's not necessarily a disaster.... we see a lot of exaggeration in pro cycling which no one cares all that much about. E.g., "Démare came past me at 80kmh" and so on...0 -
