With the impressive launch at the 2008 Tour de France and the continued success of the Colnago EPS in 2009 it remains the top lugged carbon frames made in Cambiago, Italy. The EPS stays true to the traditions that have made Colnago the most respected bike brand in the world. The EPS is a lugged frame offered in 22 standard sizes, 14 in a traditional geometry and 8 in the sloping geometry this allows the rider to find his “customized – standard” Colnago. The C-HS1 (Colnago Headset System) is used on the EPS; it is a tapered fork with a diameter at the base of 1” 1/4 to 1” 1/8. The geometry and the carbon lay-up guarantee a superior level of handling, power transfer and comfort.

• Lay-Up Optimization: The structure of Colnago’s EPS frame has been completely re-done, in the tubing and lugs. We have used 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 (FEM), Colnago has created an extremely accurate, optimized carbon fibre 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 vary from a conical top tube 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 to the new Colnago EPS frame.
• 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. C-HS1 allows easier assembly and maintenance without removing the entire headset assembly and 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.
