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.
