Yoda, if they had discs, they might not have crashed to start with ;)

MikeB... WT??! 1200 bucks without a crankset????!?!?! you must have missed something there... surely?

Yep agreed entirely.
I have actually said exactly that elsewhere on either this or another forum.
I just could not be bothered arguing with Jason. :mrgreen:


May be true for the current MotoGP formula, but definitely not so for other classes, such as MotoX. Lower speeds, but many large pileups, with discs, and spokes both. Still not aware of any significant issues that can be attributed to the presence of discs.

In any event, I believe the UCI ban on discs based on safety grounds is fallacious. They have been in use now for many years and have proven to be both effective and safe. Exposed chains and sprockets are more likely culprits – as anyone whose hand has slipped while loosening a pedal axle will most certainly agree.

Where have they been in use for many years where there is high speeds (40km/h+) with riders riding in tight formation??
Certainly not in MTB or CX.
Think about what you are typing before you hit the keys.
About the only time MTB riders are in tight formation is when they are jammed up behind each other in singletrack.
From experience, at these times they are probably going so slowly that they are basically stopped.
CX is likely about the same.

And why are you loosening a pedal axle whilst racing your bike?

I am out of this argument.
Moto has NOTHING to do with bicycle racing.

Not from what I know. Its almost 400 per lever (560 for the Red ones !) andthen 300 for the RD and about 110 for the FD.

Wish I was wrong on the lever price, but I think im right

Personally think you are more likely to get burns from a disc rotor than amputation. A bladed wheel has the potential to do way more damage IMO. Just ask Dimma about his incident with the Kangaroo.

Discs will be legal. I give it 3 years.

But you need to try and stop a car without hydraulic assistance a few times. It feels identical to the cable brake system on a bicycle.


I think you must be talking about vacuum assistance there. It won't stop at all without hydraulic assistance :mrgreen:
I would argue hydraulic rim brakes are an increase in complexity and potential serviceability for naff all net gain. Modern rim brakes offer fantastic power and modulation in the dry. Problems in the wet aren't down to a lack of clamping force, so can't see much of an improvement there.

Modern brakes are good yes, but discs are better.

have you ridden a disc equipped road bike yet ? Not just a MTB or CX, but a roadie.

When you have tried one, then come back and offer opinion

Since when have I had to have actually have done something to have been able to post my opinion?
And since when did you become a moderator and be able to tell people what to do?
When you have the word Moderator under your user name come back and tell me what to do.

I was not talking about discs. I think you missed me mentioning hydraulic rim brakes in your haste to defend disc brakes. :P

oops. Was on phone and without glasses


And sumgy, ease off. Some opinion is presented as fact, and that's how it came across. Too many people judge things without actually trying.

Meh, 1st world problems.

There is no need for hydraulic brakes of any sort on a road bike and if the cable starts to leak then you can't do anything about it without changing an expensive cable and bleeding the brakes. But with cable brakes you can tell when your cable is about to ware out and needs replacing and can be done before it happens. Also cable brakes are far more servicable and cheaper to replace.

There is some press showing in July (for shimano that is) that I'm hoping to get an invite to :D

There's no need for bikes, theres all sorts of alternatives... :roll:

I choose to ride bikes, and choose to ride both a roadie and a mountain bike. Both of my bikes have hydraulic disc brakes because in my experience, they offer the best braking that i have tried. Not sure why anyone else feels the need to say that they aren't needed unless they add that THEY don't need them. :?

I don't NEED them, but having tried them (and for some too) I think they are way better.

But if they are not for you, then that's great.

The one thong that is significant is that on all the reviews to date have been positive, and have seen where they are better than rim brakes, but again, they don't need to convince me :mrgreen:

Sounds like a comment from a mid 90's mountain bike magazine :)

Hydraulic disc brakes require next to no maintenance. I think I have bleed 2 sets of disc brakes in 10 years. Brake pad changes are a lot easier as well.

Basically that line of argument is a moot point.

Yep, strictly speaking derailleurs are not needed either, but they have useful advantages. :smile:
