The top frame from the Colnago Revolution ’10 project, the EPS is a full carbon lugged frameset that offers incredible performance. Evolved from the Extreme Power model, which was designed for top sprinters like Petacchi, Freire, and Zabel who can generate tremendous power under acceleration, this machine also uses lugged construction to help eat up the road vibrations of the most epic riding conditions.
Assembled with ultra and high modulus (HHM-HM) unidirectional Omega carbon fiber composite with a 3K twill finish and monocoque carbon fiber lugs, this frame is also made by hand in Italy. Beyond the 14 traditional sizes and 8 sloping sizes, custom sizes and paint schemes are also available upon request.

Lay-up optimization: The structure of Colnago’s EPS tubing and lugs have been upgraded with the help of CAD design. Colnago uses ultra high and high modulus (HHM-HM) unidirectional composite with a 3K twill finish. During the development of the EPS, thanks to 3D design & Finite Element Analysis (FEA), Colnago has created an extremely accurate, optimized carbon fiber composite lay-up in the key zones where force is transmitted to the road for an incredible ride & performance to reduce vibration & stress from irregular road surfaces.
Multi Shape Tubing – 3PRS System: Colnago’s new EPS frameset features a unique new 3PRS System of multi-shape tubing which manipulates the tubing based on its purpose in the frame. The top tube is conical, with a 40mm diameter at the head tube that tapers to a 35mm diameter at the seat tube lug. The Colnago EPS down tube has a constant diameter of 44mm from head tube to bottom bracket, with four 3PRS internal reinforcing ribs of varying widths and thicknesses inside the down tube which confer extraordinary stiffness and power transfer. Overall, this is an improvement over the technology of the C50 or EP framesets of years past. The seatstays of the EPS employ a convex design for optimized braking, while the chainstays are oversized and beefy to keep your sprint snappy.
Colnago Headset System / C-HS1: One of the key points of the Colnago Revolution development project is the introduction of an all-new headset system, the C-HS1 Colnago Headset System. This is a special, semi-integrated headset that uses 1”-1/8 bearings in the top race and 1”-1/4 bearings in the bottom race for extra head tube rigidity and more steering stability and precision. Compared to other integrated headsets, Colnago's C-HS1 allows easier assembly and maintenance without removing the entire headset assembly, while also protecting the frame. Using a similar design philosophy, the EPS bottom bracket has a easily removable CNC titanium insert to facilitate maintenance.
Colnago Carbon Fiber Fabric & Epoxy: With over two decades of experience building the finest carbon fiber bicycles, Ernesto Colnago used his expertise to choose the finest carbon fiber fabric & epoxy for his new EPS frameset.
Colnago EPS Carbon fork & tubing diameters: Colnago new EPS’s has a 35mm seat tube diameter that uses a 31.6mm seat post. EPS also features the all new Colnago New Star carbon fiber fork that was specifically developed for C-HS with it’s 1”1/8 - 1”1/4 diameters. The Colnago New EPS carbon fiber fork features improved steering & stability thanks to the new fork blade shape, maximum strength to absorb shocks and blend smoothly with the new 1”-1/4 diameter of the bottom of the head tube.
