Is this the lightest ever disc brake bike?

This custom-built Cannondale Super Six Evo Disc tips the scales at 5.67kg. We take a closer look to discover why it's so light.

Making a brief appearance at the Cyclist office today was a custom-built Cannondale Super Six Evo Disc, which when put on the newton meter of judgement displayed a reading of 5.67kg, and led us to believe that it could be one of, if not the lightest, disc brake bike out there.

The bike was built as a collaboration between Cannondale and the EC1 Collective. 'We asked the members of the Collective, a private members community for road cyclists, to help us select the parts,' says EC1's Mike Gluckman. 'Over weeks of deliberation and discussions we ended up working closely with Tune Components from Germany and a handful of other choice German weight-weenie manufacturers like BrakeForceOne & Schmolke.'

At its heart is the brand new Cannondale Super Six Evo Disc, with a brand new colourscheme, but there are more than a few modifications that have been made to the model, indeed largely attributable to German parts manufacturer Tune, that have enabled it to boast such a low weight - disc brakes or otherwise.

The cockpit is perhaps most eyecatching, with a Schmolke Oversize Evo SL bar serving as the foundation and decorated with an exceedingly 90s-esque pair of Brake Force One brake levers, sprouting cables skywards in a primitive fashion and sacrificing the possibility of a hood hand hold, all in the name of weight. The levers are hydraulically linked to a set of Tune Kill Hill Black Edition callipers, typically more used in MTB, and in turn 140mm disc rotors. 

The seat tube is devoid of a front derailleur, as with the single Cannondale Hollogram SISL chainring set up at the front it's not necessary, which could be a sign that Cannondale see this trend continuing to grow. The frame comes with a derailleur mount as standard though, so Cannondale has drilled out the rivets, filled them, and then laquered over the carbon, to neaten things up with this modification.

The build is completed with a Tune Komm-Vor Plus carbon saddle, an alloy Tune stem and a pair of 1,400g wheels, with both Tune carbon clincher Tune rims laced to an anodized blue Tune hub.

Road bike. Disc brakes. Primitive but functional. 5.67kg. Bravo Cannondale (and collaborators).
