Full carbon with lugs ColnagoRevolution is the top development and design project for Colnago in 2009, and the all-new top of the range Colnago EPS is the first star from the innovative ColnagoRevolution project. Evolved from the Extreme Power model, which was designed for top sprinters like Petacchi, Freire and Zabel who can generate tremendous power under acceleration.

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 – 3 PRS 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 ColnagoRevolution 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 Fibre Fabric & Epoxy: With over two decades of experience building the finest carbon fibre bicycles, Ernesto Colnago used his expertise to choose the finest carbon fibre 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 NewStar carbon fibre fork that was specifically developed for C-HS with it’s 1”1/8 - 1”1/4 diameters.

The Colnago EPS carbon fibre 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.

“It fits you, not you fit it” The new Colnago EPS, the new top of the range model is the simply the maximum in custom made bicycle frames and perfectly synchs up with the well-known fitting philosophy of Colnago.
