For me, who races and trains
For me, who races and trains on road bikes and does occasional mountain biking and can see how great discs can be in the right circumstances, I just don’t need them.
In years of riding training and racing I don’t think I have ever crashed as a result of not having disc brakes, my rims last just fine and modern carbon rims now have hard coatings.
I also just don’t need to have to shell out a load of dosh on a new bike right now when there is not the need.rogermerriman
the riders being burnt by
the riders being burnt by disks in a crash doesn’t sound likely.brakes get hot, on steep twisty descents, and so on. this watching the pro races isn’t where you get pile up’s which tend to be, either at or the build up to a sprint finish, or rolling along and some one touches a wheel.
in both cases the disk should be frankly cold.
Compatibility sounds is more of a issue but by no means unsolvable.

As someone that does race,
As someone that does race, and has found himself at the bottom of a number of big pile ups, my only real concern with the use of discs is the chance of injury argument.There is a difference between your average fall at a 3/4 cat crit and pro racing. In the latter you are in much tighter, larger groups, and often the circuit is barriered in… which means that you all end up in a big pile on the floor.
So whilst I think the threat is low, I think the chance of a burn or a slice is real and should be investigated before we move forward.
Other than that, the only other thing is the faff… I love to polish a bike… cleaning the MTB is a constant case of contamination avoidance because of the disc pads.

If you race, you have the UCI
If you race, you have the UCI rules to abide by, end of discussion.
If you don’t race, you’re mad not to buy disc brakes where you have choice on the cost of trashing your rims alonemassspike

OK you need some disposable cash but you aren’t blocked from riding with their gear as fast as you can. I can see why the manufacturers are worried about the looming disconnect between the peloton and the avid cyclist. You already have the minimum weight restrictions divide, tubular vs clincher/tubeless tires, etc. If you add brake differences to the pile, then the consumer may start to lose interest in what the pros use which wont be good for sponsorship’s. Golf would be the counterpoint to cycling — every new innovation the pros use ends up on the retail shelf (“what wins on Sunday, sells on Monday”).

With discs, bike companies
With discs, bike companies have discovered a great new way of selling us a new bike to replace our “old outdated” bikes.
What the pro riders use is irrelevant – look to F1 motorsport, you drive what the rule makers say you can – be it V6, V10, petrol, hybrid etc and the rule makers are driven by the wishes of the major sponsors.
The real reason against discs has to be the noise or more precisely the risk of noise…..a trip to any trail centre usually includes the sounds of tortured pad on metal. Now how would that go down on the Sunday club run??HalfWheeler

Look, I’ve got some 1st hand experience from this. My winter rig has shockingly bad brakes. Can’t afford to replace them at the mo. It makes life on a club run, erm…lets just say interesting! I’m getting away with it on a Sunday run. Wouldn’t try it in a chain gang or road race.If you haven’t already, you should change the pads. Clarke make some really great pads that you can buy for under a tenner from CRC. That alone accounts for 80% of the difference between good and bad brakes. Better brake callipers aren’t that expensive either, really. I bought second hand Ultegra callipers (in old school shiny silver) for £25, but you can get SRAM Apex, or Shimano Tiagra/R450/R650 brand new for under £40.
Ach…it’s a cross bike so it’s got cantis. I’m already on the third pair of cantis. Replaced the blocks only a few months ago. It’s, supposedly, 105 standard of cantis. My dual pivot 105s can stop with half as much braking distance.
Xmas is coming up, need new pedals and shoes, club fees are due as is BC and race licence fees…

Glynr36 – fair point (although I suspect the number of pros is less than 1%). Maybe the two will “decouple” – you can’t ride tyres wider than a 33 in a UCI cross race (and they occasionally wander around with a little plastic block to measure tread width) but BC events allow all sorts of bikes, with all sorts of tyre widths, to be ridden.
abudhabiChris – on other hand, I am not so swayed by different ability levels argument. Braking is only one of a number of ability issues to deal with, and even then not a very important one. In my limited experience of road racing in BC events, handling (including sitting in a bunch), cornering and sprinting in a straight line are higher up the list of skills likely to cause crashes by virtue of different ability levels than braking.
So if the point of the article is to show that it may be inadvisable to buy a disc equipped road bike if you only have one bike and you want to use that bike to compete in BC sanctioned events, it has some merit. Otherwise I think the article itself is irrelevant.

You seem to have slightly missed the point. You like discs, that’s great. The original article was just about people from pro teams who also liked the technology but where unsure about its application at the moment in the pro peloton.
It is not is much that pros can’t use discs, but that some do not want to when road racing.

Paul J wrote:All those going on about the power and modulation of disc brakes, and stopping power in the wet, are *utterly missing the point*. That’s irrelevant to racing. What matters in racing is that your equipment is as good as your competitor’s. Whether it’s shit or not is irrelevant. Racers can race bikes with shit brakes (e.g. 70s or earlier?) or good, doesn’t matter, they’ll race.Although I largely agree with you, interviews with riders i’ve seen in the past about braking/descents in the cold, wet or both make me think that some of them might actually appreciate something that is better in real terms as well. It’s pretty irrelevant what we think though – it’ll come in because some people / businesses want it in.
the infamous grouse
disc brakes don’t increase
disc brakes don’t increase cornering speed.if you leave your braking point too late for a corner and subsequently crash into the person in front, it’s your fault.

For me the concern is partly the braking power but more the fear of discs in a big pile up. I’m not expecting disembowelment or severed heads, at least not more than once or twice per season, but I am expecting to see some nasty slices.

if you commute in all
if you commute in all weathers discs make some sense, saves the rims wearing out, but you do have to be VERY careful about spraying the GT85 about it will destroy your brake pads by contamination.As for discs v cantis, Magura’s are more powerful, have a think about why many trials bikes still use them, but all rim brakes suffer in wet weather. Off road with mud, discs make more sense because rims get covered in crap and wear out. Personally I got through a set of 217s in 8 months.
There have been a few cases of ice-tech discs melting, which isn’t really a good sign, pros might not use brakes and might not have a habit of dragging them, thus keeping the temperatures down, but “normal” riders aren’t pros, either the brakes cope with being dragged or they don’t, the rider isn’t going to change.
On a race bike meh, it makes f’all difference. I would suggest in a few years everyone will be on discs because that is what will be available. Any other excuse is just that.
Ask why the industry has pretty much decided to scrap 26″ mtbs in one year. Nothing like planned obsolesce.
Final point, go on any MTB forum and you will find the “my brakes don’t work question” followed by bleed them comments. cable caliper brakes just work, disc brakes are more faff, they do need more care. And if the brakes say SRAM run away they will be s***.
