Selling a new Colnago K-Zero TT frameset size medium.
Sold as a frame set with handlebar/stem/aerobars included. This Colnago stands out for not only its sleek performance and light weight but its astounding good looks.
In its most simÂple terms, aeroÂdyÂnamic drag is proÂporÂtional to the square of the speed - in other words if you ride along at 20kph, and then increase your speed to 40kph you will expeÂriÂence four time as much drag. So havÂing a bicyÂcle that has a low amount of drag to begin with gives greater benÂeÂfits the faster you ride.
The brakes are fully inteÂgrated into the fork and the frame, withÂproÂmisÂing the strucÂtural integrity of either. With the rear cable fully enclosed to furÂther reduce the aeroÂdyÂnamic drag, the rear brakes are then hidÂden with an aeroÂdyÂnamic cover which aids the conÂdiÂtionÂing of the airÂflow along the underÂsides of the chainstays.
The hanÂdleÂbar and stem assemÂbly is one bespoke unit. Unlike traÂdiÂtional bar/stem interÂfaces we have choÂsen not to turn the aeroÂdyÂnamic proÂfile of the bar into a round shape to inteÂgrate into the stem. Instead, the stem is of the same proÂfile shape as the bar. This has led to a stem/bar joint where the stress levÂels are also greatly reduced, allowÂing us to make a lightÂweight bar and stem sysÂtem that is also aeroÂdyÂnamÂiÂcally supeÂrior to a traÂdiÂtional sysÂtem. The clip-on secÂtions can them be tuned in height and reach for rider posiÂtionÂing, thus keepÂing the main aero secÂtion of the gars in the optiÂmal posiÂtion, and within the UCI regÂuÂlaÂtions. Another addiÂtional feaÂture of the new stem/bar interÂface is plete inteÂgraÂtion of the cables required for shiftÂing and brakÂing. Again, this leads to small but cruÂcially imporÂtant drag reducÂtions in one of the key areas of the bicycle.
Several NACA derived tube proÂfiles were tested throughÂout the design process, again, all within the UCI regÂuÂlaÂtions. It is the use of these proÂfiles in both stanÂdard and modÂiÂfied form when viewed as plete sysÂtem that form the basis for the K.Zero chasÂsis. The design looked at the interÂacÂtion between proÂfiles as plete sysÂtem, and not as indiÂvidÂual tube proÂfiles. This is an area of design flow that has always been a Colnago way of thinkÂing. A bicyÂcle is plete sysÂtem, not just indiÂvidÂual parts, and as
