Disc Brakes on a C59

[k_gibbo]

I am shocked... Just saw this on WW forum...

that looks dope to me. I want one

 

[Spider1964]

I. Want. One.

RDV4ROUBAIX has been hinting at the introduction of disc brakes for a while now... looks like it'll happen sooner rather than later?

 

[dougvdh]

It has some pretty tight front fork crown clearance for a bike that would otherwise make for a great classics bike. It doesn't appear that it would take a 27mm tubular very well.

That said, pretty sweet set up. Any idea who's making those brake levels/DI2 shifters?

On another note, I can't see the pro peloton switching over any time soon. Unless the switch was done wholesale by all the riders, neutral wheel support would become a total nightmare - 'will that be a shimano, campy, 10s, 11s, disk or non-disk wheel that you need?'

Well Done to Mr Ernesto Colnago & his team for making this happen now.
The current UCI rules do not allow disc-brakes for road races so it will take a while before the pros/top-riders use them. I suppose the immediate market is for the serious sportif riders.

Yep, superannuated fat old blokes drive the upper-end bike industry...a lot of furry little lycras are sacrificied to make their assos kits.

Awesome! Simply awesome!! I wonder what the rear spacing on the C59D is, 130, or 135? This is going to be the deal breaker I think. Once a standard for road disk is agreed upon we could very well also see the departure of 130mm rears just as 126mm died in the 80's-90's.

Surely the standard will be 135 since it already is for mtb?

I don't get the build they did. I see Shimano DA DI2 but with some custom Colnago brake levers. Are they making their own brifters for use with DI2?

They have to be custom Di2 with hydraulic levers. I really expected to see a serious CX bike first especially since this is not road race legal (yet)
So there must be electric buttons somewhere up on the levers or the levers may have been made with Di2 and braking in mind as they are not shimano.
The bike is exciting and looks like a serious race bike. I am looking to the future when Campy and Shimano have fully developed hydraulic Brifters. For this project it looks like adding electric buttons was easier than making a DA hydraulic lever. Except I suspect the shimano lever is well along in it's development.
Very cool and I am surprised at how clean the lines got by moving the brakes to the hubs.
I will want 1 but I want a tandem first and this kit is ready for tandemania.

 

[Boeing]

well timed given the Shimano and Avid rumors

Well, don't bank on it. That's practically too much braking power for the road racer. Someone's going to come out with a smaller rotor that will sweep big-money consumers off their feet.

Also note, Colnago's got the disc version of their 'cross product posted too. Talk about overkill!

I'm assuming the Colnago carbon is an OEM product which means you should see a couple more brands releasing a similar bike in 2012 until the bigger OEM's are done waiting for some standards to settle and Shimano to be up to full-speed on producing the levers. Even then supply of the lever mechanism will be constrained for a while.

The rear width standard is actually a god question.

The rear standard for Mountain Bike is shifting away from the 135 as you know DW. but for different reasons

Ah! I'm not up to speed with mtb developments. Was thinking of minimising tooling costs, I'm assuming that light weight xc disc hubs would transfer to road but using a smaller rotor? Interesting times!

The 135 referred is not the rotor size it is the width of the rear hub or the width between dropouts.
Too small a rotor and the disk cannot cool enough and that would risk glazing the pads.

Hey, Colnago doesn't do gimmicks -- look at how their C50 made split chainstays a standard for road bikes. Now with discs, people who have never lifted the rear wheel under hard braking can have even more stopping power.

 

[FignonLeGrand]

I think this is a really important bike, a colnago with disc brakes is a real game changer. Disc brakes are clearly a step in the future direction of braking for all bikes. When considering the technology used in a modern bike, bits of cork sandwiched by a wire on the outer rim of a wheel is hardly the leading edge in stopping technology.

 

[Gaear Grimsrud]

...all bikes.

Yes, I'm sure a standard to accommodate discs will proceed as smoothly as the bottom bracket standard(s).

It's funny that some of the same people who scoff that pros are paid to ride "plastic" frames are rubbing their hands at the prospect of pros validating their favorite bits of unnecessary tech.

I'm sure discs have a future, just as electronic shifting has a future: as a niche for those who can't spend enough on their bicycles.

Have you ever done a technical descent - particularly on carbon wheels - on a wet day?

So you're going to have to have a wet weather bike and a fair weather bike? And how hard can you really brake with the traction available with 20-23mm tires in the wet? (In my experience with aluminum rims in the wet, I have too much stopping power for 23mm tires. Disc brakes would be complete overkill for the conditions.) You'd have to run wider tires to make the disc brakes worth it, whose weight probably wouldn't appeal to someone trying to get UP the climb as quickly as possible.

I'm with Gaear on this one. An answer to a non-existent problem that we'll all be encouraged to spend our hard earned money on...

Spending hard-earned money on unquantifable benefits would seem to fit with your screen name...

HP stays weren't a gimmick, neither is conical tubing. Now you're probably going to tell us straight blade forks are a fad.

 

[Gaear Grimsrud]

HP stays weren't a gimmick

Why the past tense? If they weren't a gimmick, they'd be on current models.

Nope, it's been almost 4 years since the B-Stay was featured. So normal stays are back, and even stiffer than before. You ever ride a C40 and a C59? I raced both versions of the C40, 1st with normal stays, 2nd with HP stays. Made a huge difference in lateral stiffness when sprinting. My favorite Colnago to race wasn't carbon even, it was the aluminum Dream, also had HP stays.

Ernesto has always been very good at acting based on feedback from his sponsored riders. They tell him the Super is to soft, so comes the Master, C40's were great for Spring classics, kinda too soft in the rear for the rest of the season, so comes the HP and B stays.
