Looks like a lot of borrowed ideas from other recent TT bikes but some how I think Colnago have pulled it off quite nicely

When, where and how much?
Magura RT8 - not available (except to TT bike makers) from what I can make out.
Here's a possible alternative

In regards to all them disc brakes on road bikes, surely it will never catch on as roadies are weight weenies. In addition the the weight of the actual brakes, it will prevent riders using all the light weight racing wheels they are accustomed to.
Alessandro Colnago claims that the total package adds around 200 grammes to the overall weight of the bike.

^ i think that they will be able to get nicer rims now that they dont need braking surfaces so wheels might get a better ride, but the extra mechanisms aren't exactly aero and as tester pointed out spoke counts might have to go up too. Roadies are more worried about aerodynamics than weight these days

It's a modern TT bike, that's not ugly. Bit of a surprise.

Oh yeah of course, you wouldn't get the flex through the spokes on a Trials bike using Magura Rim brake, as opposed to Discs.
Less of an issue on 20" but on 26" discs don't feel as solid. When you land you can feel the wheel flex more.

crankset painted white [wtf?]
non matching saddle
bars could use some adjusting/different stem.Yes, the flutes got some white color, wtf is wrong about that?
An Arius Professional saddle matches this 1972 bike perfectly, it wouldn't work with an Italian frame set, but we are talking about a Dutch bike here.
It is an 3ttt pista bar and stem combo, these were made to match, so why to use another stem?

they were especially produced for the frame. a road bike version will follow "later"

Note no "what?" and what was the possible alternative?
Hmmm I was hoping for just the brak any one wanna go halvses on this to get the pair?
Nothing I was looking at the wrong thing.

matching cranks with lugs outlining? doesn't appeal to me.
and I am sure there is a period correct saddle in brown, too.
combo - yeah, they were made to match. but leveling bars like this makes this stem's purpose pointless, Id say.thats your bike?
you got all defensive mate.
hope its not, because its simply ugly. -

I'm not fully bought into disc brakes on road bikes.
I think there are advantages to the design and materials for rims, tyres and innertubes by shedding the braking surface and removing the heat (carbon rims).
But, you've moved a lot of that into the design of the forks, brake mounts, hub and spokes and spoke patterns.
Rim brakes are incredibly light and incredibly effective. Then when you look at the kind of heat that will be generated on a disc if you really are a pro rider coming off a mountain at 50mph+ and braking before corners for a good 20 minutes. Rim brakes are just so damn effective and predictable.
I do think discs will eventually win, and I'm all for pioneers solving the problems. But I can't see discs touching the pro tour for a long while yet.
Are there any UCI rules that specifically prohibit them though?
I've been riding discs on MTB for 10years + now. And in the UK, I've never experienced overheating to the extent of noticeable reduction in brake performance (came close on a 4mile+ descent that gets steeper and steeper towards end with a 50l / 15kg backpack on).
Yes discs get hot, but they can deal with it. MTB's often do not move quickly, 10-25mph so they don't get that much air, but work amazingly well.
Road bikes, on mountain passes are moving quickly, even steep techy descents they are going to be moving a hella lot quicker than MTB / DH bikes. Therefore they will actually reach a ceiling and then cool themselves.
So Personally I don't see discs having a heating problem (even poorly designed tiny jobs like those formulas, though floating rotors are probably overkill for a road bike).I descend in fear (on road bike, old one with 80s single pull, and newer one with 90s dual pull 105s) from every mountain pass, that my tyres will blow out. Had one blow out (front!) before on a mates bike, thankfully it was open moorland and I came off in a good place, but had it been a tricky bit/ coming up on a car, might not even be here!
Watched a few road races over lakes passes and witnessed 10-15 tyre /rim explosions thanks to overheated rim brakes (1 or 2 were carbon rims / cork pads on tubs).
Give it a few years and discs will likely become fairly popular.Hope made a set of adapters in the 90s that took canti cables (CX) into master cylinders mounted on the bars/ headtube, were a neat solution, but was next to no lever 'feel', which is a lot of the benefit of discs.

hope its not, because its simply ugly.Why would a brown saddle be more correct than a black one? The tape is yellow, and there are no hoods, so there's no brown anywhere, apart from the toestraps.
I'm not understanding your beef with the stem either. What's wrong with it? The bars are slightly tilted upwards (if you consider the flats being level as the default), which is hardly unusual, and a different stem isn't going to affect that.

For aftermarket, it’ll be available in June for €599 / set.
According to the press release below, an RT6TT will be on offer, too, at €499 / set,They are a bit porky, though, at 495g for the RT8TT, and the jury is out on whether the complete package will be competitive on aerodynamic performance with something cheaper and lighter like SRAM 900TT levers with Tri-Rig calipers and Transfil Flying Snake cables, which will be about 450g/ €500

I was just interested in your opinion. But i can stand the fact that you are not interested in a conversation and rather argue without arguments.
So we better move on.

Shirly if discs have been made UCI legal for cross racing it's only a matter of time until the UCI extend that to the road.

@ Brickman. I've been using discs on my MTB for years too. They are completely wicked. However I rode an Alpine decent in Chamonix (on the road) on my MTB. By the end of the decent both my 160mm Hope mini monos were useless. the brakes didn't work due to heat, discs were purple and the front one slightly warped.. I only weigh 11.5 stone.
Purely from a design point of view it would be good fun to try and design something for a road bike. Trying to get something super light that tucked neatly behind a skimpy road bike fork leg, yet still with massive power.

Has anyone using a modern open system disc brake ever experienced overheating? I've not heard of it ever happening. One mtb race which certainly puts the brakes to a test is the Megavalanche. It drops 2000m in 30km, not all the race is down though but there are sections where you're on the brakes not far from constant for several minutes.
I think as well as the lower end of the fork need needing strengthening to put up with the torque it will need something for it to put up with the heat. Apart from that I see no real problem.
