Two summers ago Colnago debuted their Concept aero road bike. A year later there was talk of a disc brake version, which only just now becomes a reality. And the Colnago C64 took over the lightweight road flagship role earlier this year, but now a super limited edition C64 Gold sets itself even higher in 24K detailing.

2019 Colnago Concept Disc Brake carbon aero road bike

Tech details-wise the Colnago Concept Disc features mostly the same tech & design as the rim brake model. In fact Colnago has gone out of their way over the past couple years to blur any real model differentiation between rim brake and disc brake bikes. Narrow and deep tube shaping is what governed the development of the Concept aero road bike and that doesn’t change for this disc brake version.

Sure, not every one of their bikes is available with disc brakes, but when they are Colnago likes to keep the nomenclature broad. The bike is designed with flat mount disc brake calipers and standard 12mm thru-axles keeping everything clean and simple.

The bike was built up with Vittoria tires that measure 24mm wide for us, so you can see there’s not a lot of extra tire clearance in there. 28mm tires are said to fit, just like they do in the rim brake version.

The bike retains the narrow profile of its rim brake predecessor, and in fact features exactly the same geometry, down to the claimed 406mm chainstays on the medium frame. The bike is available in an eight size range (42-58cm with sloping geometry); and headtube angle seattube angle, and chainstay length are size specific across the entire range to deliver consistent handling.

The front end features Colnago’s two piece aero bar and stem combo that effectively uses a traditional round bar clamping area to provide full adjustability.

Small fairings close the gap between the aero bar and stem shapes, while under the stem is an accessory mounting point for an out-front GPS mount or this Campy EPS control box, plus internal cable routing access points beneath the bar.

The new disc brake bike even gets the new ThreadFit 82.5 bottom bracket that Colnago developed for the new C64 together with CeramicSpeed.

At the back of the bike a rear wheel cutout tucks in close off the seattube, a hidden wedge style clamp holds the seatpost, and the post itself features a recessed cutout to provide some comfortable flex.

If you want to stick with stick with direct mount rim brakes, Colnago can still do that for you in a standard Colnago Concept as well.

2019 Colnago C64 Gold, ultra limited edition 24K carbon road bike

Limited to just 64 total bikes worldwide, the C64 Gold builds on the Colnago’s revamped flagship light & stiff road bike debuted earlier this year. The handmade frame remains essentially the same, outside of the fully bling 24K gold leaf detailing and one of the highest-end build spec’s you’ll find anywhere.

If the actual gold detailing isn’t enough to show your riding buddies how rare your C64 Gold is, this little number plate under the bottle cage should remind them. The C64 Gold features the same Italian made lightweight oversized tubing that Colnago says are even more durable than the previous generation C60, joined together with Colnago’s iconic external carbon lugs.

It looks like the C64 Gold will be exclusively built up out of the disc brake version of the bike, and gets a build kit that reminds you this is a bike for people who don’t ask how much it costs. Dura-Ace R9170 groupset, check. Carbon Ti rotors, check. Lightweight Meilenstein Disc wheels, check.

You even get to sit on top of a gold-leafed saddle.

The full Shimano Dura-Ace R9170 Di2 group gets tricked out even more with CeramicSpeed OSPWs (what no 3D printed ti ones?) and a SRM x Look carbon power meter crank with carbon Carbon Ti rings. Yeah, I didn’t have the stomach to ask about the price.
