Close Up: New Colnago C59 Disc Road & K.Zero TT/Triathlon Bikes

2013 Colnago C59 disc brake road bike

Unveiled in early March, Colnago’s C59 is the second current-generation production road bike with disc brakes (Volagi being the first). Where it differs is with the integrated Di2 shifting and dedicated hydraulic brake levers without any converter. For a close up look at the braking/shifting system and a matte black version of this bike, click here.

Apples to apples, the complete frameset is 150g heavier from reinforced fork and chainstays, but Colnago USA’s Billy Kanzler say the brakes are about 20g lighter than a Dura-Ace set. So, the difference is minimal and the added weight sits low on the frame. Benefit: Lower COG. Kanzler says they’re excited about the potential for the added frame weight being offset by lighter, more aero disc specific wheels in the future.

Fork had to have reversed dropouts to counter braking forces.

Frame weight is 1100g, and it’s Di2-only to work with the Formula system, but word is they’ll have a Campagnolo EPS plug-n-play system later this year. Bike is available in July, pricing isn’t set in stone but should be around $14,000. Availability should be good since they make their bikes (in Italy) on demand. They can make up to 16 bikes per day.

This is a prototype K.Zero TT/triathlon bike that will be available in July.

UCI approved design has TRP brakes integrated behind the fork and below the chainstays with plates over the outer edges smooth airflow.

Fully internal cabling for mechanical and electronic on the same frame. Fully wind tunnel tested with “exhaust ports” at the top of the seat stays to move turbulent air from the wheels out quickly with minimal drag.

An 1-1/8″ headtube allows any common stem to be used to dial the fit, then the custom integrated stem is machined in house at Colnago to any length and rise to fit the customer. It’s mated to a Colnago aero bar and extensions.

Love the C59 as long as it’s 200% certain the discs don’t blow out on descents. I like the light colors too, screw Matte black.

@IJB One article from a website bike journalist and all of a sudden there’s a fear of disc brakes being inferior to rim brakes. Redonk.

I am 100% sure this bike is 200% more money than I want to pay for a bike.

First attractive colonago in a looooong time… Who put the TT/ Tri bike together? They should be fired… what’s with the front brake pad at a funny angle? fail…

Love the “grayed out” look!

ccolagio - 04/26/12 - 7:40pm

those look like 140mm? rotors front and back – be sure not to take too long a descent or youll get some nice brake fade towards the bottom!

cant wait to start seeing 200mm front and 180mm rears on road bikes

Mark W. - 04/26/12 - 11:55pm

cant wait to see this arguement about disc by arm chair engineers on every single bike website to be done.

I can’t wait until road bikes have disc brakes.
The fear of brake fade is BS

Chippollini – to be fair, they were already pulling the bikes apart when I stopped by at the end of the show and had to put them back together for photos.

Nivlac – some brands are charging forward fast with road disc brakes, but I heard from a lot of industry folks that have concerns over how they’ll perform in the real world, particularly the first generation of products.

R Tripp - 04/27/12 - 9:34am

– c colagio — Brake fade from discs’ on long descents would be worse than rubber blocks on rim wall?
My bigger concern would be fork construction and matching the strength needed to road compliance desired.

Any thoughts on wheel changes during race day?

I agree that the TT/Tri bike is fantastically sexy.

“Nivlac – some brands are charging forward fast with road disc brakes, but I heard from a lot of industry folks that have concerns over how they’ll perform in the real world, particularly the first generation of products.”

This is exactly why I’m not an early adopter on certain things, important things, like brakes.

The tt bike is cool, looks kinda like the Giant Trinity, minus the deep wheel cutout/shaping in the seat tube.

the TT fork looks like it was adopted from Argon 18′s E116

ccolagio - 04/30/12 - 12:33pm

i never experienced brake fade from road/rim brakes as my only bike in that category is a single speed commuter and ive never dont real mtn descents – great point though

i mainly ride mtb and dh – ive definitely experienced brake fade there going at slower speeds than a road biker will endure

i have no doubt that the designers laying up the carbon for the forks/frames could not come up with a more than adequate layup to counteract the disc forces. all im saying is 140mm rotors may be a bad choice for heat dissipation – something that discs generate a whooooole lot of
