Your next road bike: disc or caliper brake

I'm telling you, even if you offer them this they won't want it.

Tell that to this guy.... he represents the pro riders and on his own has more cycling intellect and experience than the entire hub collective

 

As he says no one knows for sure what the cause was.... let's rather wait for 100% proof and a serious injury

"A lot of riders are concerned and worried about it, and they just hope it’s not the disc brake," he said.

 

The Australian said it might take 'a bullet’ for the sport’s governing body to step in and stop its disc brake trials for a second time, but he conceded that the matter was complicated by the lack of a smoking gun.

 

It’s a bit strange how there’s one rider on disc brakes, and that one rider is in that crash. It looks pretty clear that it was from a disc brake. There are images showing that Kittel is nowhere near him, but on the other hand, if you look where Kittel crashed, his bike isn’t in view either. So the bike could have been anywhere else. In that sense, nothing is really sure, but it looks pretty clear to me."

I didn't quote Hansen. I quoted Doull who clearly said it was a cut from a disk. The red rust mark around the cut/tear must have been his dried blood that poured out from his foot that was not cut.

 

Here is the damage that caused all that blood to dry on his shoe.

 

He rides for Sky. That's not why I think he's talking out his rectum. But it doesn't help his credibility at all.

Look, it's plain to see that cut is not linear. It was caused by a sharp edge, not a straight slicing blade. It's even more evident higher up on the shoe.

Ok sorry to all that cried fowl. Not saying it was the disc, but sorry, it wasnt the barrier either. Go look at the footage. Sky rider is wedged between orica and kittel. Sky guy pushes orica guy into the barrier, does not contact the barrier himself, explaining why he is infront of the orica guy and in the road when they all came to a stop. Kittel went otb, how does that happen? Something stops your front wheel and your momentum throws you over. Sky was in contact with kittel before going down, not 5 meters away, falling to his left, meaning legs rotate anti clockwise right, under and up. There are is lot of things happening at once, but it was not the barrier, sky was falling legs towards kittel and legs away from the barrier.

The argument is against the disk, if we agree that it wasn't the disk that caused that damage, then there is no argument.

Hansen has reservations and doubts.

 

If anybody knows about riding a bike as a PRO, I'll follow his take

Odd you don't see pro mountain bikers saying it's too dangerous... and they ride in big bunches too - I don't think it adds substantively to injury risks in a crash - but on a big wet descent it will aid safety in a big way - I suspect that pro cyclists haven't realised that the tire is the braking limiter on a bike - not the brakes - and disk brakes have so much better modulation they will allow you to brake closer to the tires traction limit more safely.

 

Also - it's going to allow stronger and longer lasting carbon rims without the wear surface for rim brakes - and removes rim overheating issues - a real problem on carbon wheels.

Definitely ????????????????

 

There's a political struggle between the professional riders and the UCI

They want more say, it seems, in terms of overall safety, especially a tragic 2016

This area of contention seems to be part of a bigger safety theme

Okay so I just checked this with my shoe against my bike, and if this were to happen you:

 

- you would have to be humping the offending disc equipped bike/rider (or be on the floor doing some epic karmasutra) to get into a position where a disc could cut your shoe

- the spokes would first deflect/eat your shoe and ankle together

- your knee would get hit by a pedal/tyre, depending on your matrix skills, or a front wheel would imminently ride over your crotch

 

I just finished working for the day so that was a fun exercise I'm sure my living room floor feels violated now.

 

 

I love my disc equipped bike, just annoying that I can't ride it in WP Cycling events.

 

I also love standard caliper brake/rim brakes by the way, just added another bike with V-brakes to the collection... and here I thought I was trying n-1.

 

 

 

That said, my next road bike will have caliper brakes just so that I can ride in certain events with the rest of my mates.

 

I jumped the gun with disc brakes, so my current bike (with disc brakes) will be used for absolutely everything and anything else where discs aren't prohibited. It's costing me another bike now, but hey now you guys can learn from my troubles

Jeepers Yusran, bikes have feelings as well????????????????

Agree 100%. Riders should have more say

[Patchelicious]

Agree 100%. Riders should have more say

Doesn't matter how much say they have, it still wasn't a disk that caused that.

Hmm,

 

So I was going to start a separate thread about the new Roubaix. I borrowed a demo version of this from the Cedar Concept store this last weekend and did about 100 kms on it around the cradle.

 

It was the Ultegra specced one with cable shifters and hydraulic discs and had the hard cartridge in the front shock.

 

Disclaimer: And I am 52 years old (53 in January) and not exactly a race snake (more of a Clydesdale/Percheron). I have an older Roubaix Expert as well, and my Colnago C40 (although the Roubaix is my wife's bike now) so i have some things to compare against. I am a more leisure oriented rider than racer TBH. Mostly 50 to 70 kms in the Cradle twice every weekend and some races. I raced road bikes seriously about 10 to 15 years ago though.

 

But believe me I think this bike is a game changer. This bike is truly a new paradigm and an indication of things to come.

 

Its not the discs or the smoothness that was so apparent. They are nice, and yes the bike is very smooth over broken tar - just like a silky smooth ride. And no you don't notice any bobbing at all. It just gets on with its stuff. i did notice I was less stiff and sore after 50kms compared to my Colnago C40 (which is very stiff).

 

So a tick for fatigue reduction. Also a tick for smoothness and comfort - it's a bit higher in the front and its a really comfortable ride - your back isnt too flat. If you want that (and I do).

 

But one thing stood out about it. its the handling.

 

There have been some articles about it already, but its true. As you now have suspension, the wheels stick like dog poo to a blanket even over rough chattery corners. And that means higher corner speeds and a bike that literally feels like it's glued to the tar, that asks to be thrown around and that inspires confidence in the rider. It handles very neutral, it's not skittish and quick to turn, it just sits very stable and gets on with things.

 

And if there is one thing that leads to smile factor it's a bike that does this (at least for me). I was coming in to corners really fast to test it, and it just felt completely solid.

 

Now couple that with the discs and you have a package that can brake better than any rim braked bike and carry much higher corner speed, because it has suspension. This is a light bulb moment on road bikes. The first pseudo suspension road bike that doesn't rob you of power - and its really amazing. It must be a bit like the first crude suspension on early motorbikes - there was no going back (look at MTB).

 

Its also different to the Trek Domane in that it has vertical compliance not horizontal (which in suspension terms in the holy grail)

 

Even the 25mm tires were able to run at about 7,5 to 8 bar as the suspension is now not in the bigger tires, so no need for 28mm or lower pressures. So less rolling resistance and weight if that worries you.

 

And it accelerates quickly - short sprint efforts were no problem.

 

Its like the one Tread article where the guys observed that South African MTBers are crazy to ride the hard core race oriented XC machines they do - and about 80% of the fields would have a better day if they had a longer travel, slacker bike under them (like the Specialized Epic vs Camber debate). This bike is the same. 80% of the folks out there should ditch their super rigid carbon road machines for something like this - and they will go a lot faster and also feel a lot better. Its that simple.

 

So no you dont need the discs (I have said that somewhere else on this string) and you can ride any road bike with rim brakes forever, it will do the job.

 

But this bike really does change the landscape going forward.

 

Go and test one - you will be in the order queue as well.

 

PS - I reckon Cannondale are dusting off their old Headshock round about now...

I know I'm late to this, but BAZINGA!!!

Max stopping power is at full lock - but there is more to it than just max stopping power - the tire has a limit on traction in total - both for stopping and direction changing... so if you use 50% for stopping you only have 50% available for turning - so 75% stopping 25% turn... 100% stop means 0 traction for turning... this is why brake modulation is important - a good example of this is to try left foot braking in your car - given that most people have little or no ability to modulate their left foot properly when driving without a lot of practice - try it in the absence of other traffic...

This is why, despite being a Clydesdale, I'm a ripper in a gokart compared to the average population.
