Description

About Colnago C60 Ltd 85th - Ottanta 5

Ernesto Colnago has reached the milestone of eighty-five years. From this immense joy and excitement comes a bike, yet another masterpiece from a lifetime of inventing and creating bicycles. It’s called Ottanta5 – a custom-made jewel built around the C60, a unique and inimitable bike frame, handmade one by one.

The next generation carbon frame masterpiece has been released to the world. A new standard of excellence has been set by Ernesto Colnago, leaving a benchmark standard for others to attempt to equal.  

The Ottanta5 is constructed of the highest quality carbon fiber, with star-shaped tubes and lugs – a proven design element tested over the years, beginning with the Master. The C60 has bigger tubes with thinner walls, and the same thing can be said about the lugs – they are larger and stiffer, designed with the same shape present on the tubes. In summary, this gives the C60 incredible stiffness and torsional rigidity without adding weight. The lightweight alloy rear dropouts, completely redesigned for the C60, also reduce weight and provide greater lateral stiffness. The frame is available in 19 sizes – an unparalleled amount.

Ottanta5 will be available in a limited edition of only 85 pieces.

Features
Headtube

The most striking difference between the C59 and C60 is the new tube shapes and its matching shaped lugs. The main tubes are shaped in the famous star design of the Master tubes the full length of the tubes, with  no round cross section where the tubes meet the lugs. This is a first for Colnago. Lateral stiffness of the entire  front triangle will increase. At the same time, the impacting forces during a rough ride will be better distributed,  ensure a higher impact resistance. It may look simple, but achieving the shaping of the head-tube in this way  is extremely difficult. Tubes and head tube lugs must be manufactured with paramount precision and tolerance.  As a direct result of this technical improvement, the vertical wall found in the C59 was able to be eliminated,  further reducing weight while adding comfort. This feature, unique to the C59, was a limiting factor in the design  and manufacturing process. The full length star tube on the C60, by comparison, allows better control of the wall  thickness and lamination of the entire length of the tube. This is a huge step forward regarding strength, reliability  and comfort.

Bottom Bracket

The heart of the new C60 is the bottom bracket. The dimensions of this masterpiece, especially  when compared to that of the C59, have been created to ensure the ultimate in lateral stiffness. The  star-shaped tubing inserts provide more stiffness and a better distribution of stress. This allows for  significantly reduced wall thickness. This particular section of the tubing has required a considerable study  of the coupling tolerances, to ensure a coupling of tube (male) and lug (female) at the highest precision and  tolerances. The system of internal cable routing is now an integral part of bottom bracket junction, forming  two structural ribs that add strength to this most critical area of the frame.

Downtube

The second major difference between the C59 and the C60 is the new oversized downtube. The new shape  of the bottom bracket allows for the use of a much large tube diameter, thus greatly increasing lateral  stiffness. With a square section of approximately 66x52mm (the C59 was only about 44mm) this tube  represents the largest tube ever produced by Colnago. This increase leads directly to more efficiency, while  at the same time reducing weight without sacrificing comfort. Like the top tube, the star-shaped profile of  the downtube runs the full length of the tube as it enters the lug, better distributing negative forces fromthe  road surface. This tube profile improves lateral stiffness and efficiency, reduces weight and increases comfort.

Seat Tube

The C60 does not use a round seat tube in conjunction with star tubes and lug technology. This is another  first for Colnago. In favor of a round tube shape, the seat tube becomes strongly asymmetric as it reaches  and enters the bottom bracket lug. Due to the space required for the front derailleur, it is not possible to  exploit the full width of the bottom bracket shell in the seat tube at this juncture. The solution is to use an  asymmetric tube, with a width of 30mm on the left side and 21.5mm on the right half of the tube, for a total  width of 51.5mm (for comparison, the seat tube of the C59 is only 34.9 mm). To further maximize lateral stiffness  and quick response to handling input preferred by Colnago’s professional racers, as well as more dynamic road  performance, the C60 continues to use a 31.6 mm seat post. Despite the dramatic increase in size, the weight of  the C60 seattube is actually lower than that of the C59. This is the result of uncompromised design, material and  construction methods.

One Piece Dropouts

Another new feature introduced with C60 are the forged, CNC-machined one-piece dropouts. With the C60,  Colnago has worked hard to make the connection between the frame and the rear wheel a true masterpiece.  Colnago has always been proponents of aluminum dropouts for strength and reliability. The new C60 dropouts  weigh less than many products made of carbon fiber, but with absolutely incomparable stiffness and strength.  The three dimensional design in particular helps the dropout maintain lateral rigidity in even in the most  demanding situations. This increased stiffness will help also in the event of a crash – where the newly designed  inbound derailleur hanger will more consistently break rather than the dropout itself. Colnago has paid attention  to the smallest details on the dropouts, such as the milling on the drive-side dropout to cleanly route the cable of  the electronic groupsets with no interference with the quick release lever during wheel changes.

Painting

Even the paint is done by hand – airbrushed in a gloss-silver color with arabesque decorations. The logo on the head tube and seat tube is the first Colnago logo created in 1954.

More About The Manufacturer Colnago

Colnago Ernesto & C. S.r.l. or Colnago is a manufacturer of high-end road-racing bicycles founded by Ernesto Colnago in 1954 near Milano in Cambiago, Italy. Instead of following his family's farming business, Ernesto Colnago chose to work in the cycle trade, apprenticing first with Gloria Bicycles at 13, subsequently taking up road racing. After a bad crash ended his racing career, he began subcontracting for Gloria, opened his own shop (1954) and built his first frames the same year. Much in demand as a racing mechanic, he was second mechanic on the Nivea team Giro d'Italia under Faliero Masi in 1955, eventually being employed as head mechanic for the Molteni team of Belgian cycling legend Eddy Merckx. The company first became known for high quality steel framed bicycles, and later as one of the more creative cycling manufacturers responsible for innovations in design and experimentation with new and diverse materials including carbon fiber, now a mainstay of modern bicycle construction.
