Colnago CLX Ultegra Complete - CJBW
A perfect balance between stiffness, lightness and comfort.
Fork - Design and functionality. It has a monocoque carbon-fibre construction and features straight blades. The narrow base widens at the top. The head-set bearing rests directly on the cone-shaped carbon-fibre head. The design enables covers measuring up to 28 mm to be mounted. The dropouts are made from aluminium.
Carbon-Fibre Dropouts - Light, Solid and Elegant. The dropouts in monocoque carbon fibre are a superior solution to your needs. The internal dérailleur hanger is replaceable and offers considerable advantages in terms of strength and weight. The right-hand dropout has an opening for routing the cables of the rear dérailleur, whether it be a mechanical or electronic system.
Seat Post - Less diameter more comfort. Made from carbon fibre with a lightweight-alloy head, it has a diameter of 27.2 mm and is smaller and more lightweight than an oversized version. The reduced diameter provides better rider comfort on rough terrain. The closure system is an integral part of the top tube.
Bottom Bracket - Ceramicspeed - Reliability without compromise. The ThreadFit 82.5 is an unimpeachable solution which combines the reliability and practicality of a threaded (BSA) bottom bracket with the width and the exceptional rigidity of the PressFit standard. Thereby, the ThreadFit 82.5 boasts two new cups in lightweight alloy which can be easily removed, if required.
Brakes - Maximum security and compatibility. The braking system has a traditional design with two brake bodies located at the front of the fork and bridge which links the seat stays on the rear triangle. This solution allows for extraordinary ease of use and maintenance as well as being compatible with all groups.

Fulcrum Racing Quattro Carbon Clincher
The Fulcrum Racing Quattro Carbon takes the company's reputation for producing wheels with racing performance and everyday durability a step further by offering carbon construction and a wider stance for better aerodynamics, lower rolling resistance and enhanced grip. They're perfect for all applications, for the hardened racer or the weekend warrior alike.
The Racing Quattro Carbon boasts a 40mm rim height, as the 'Quattro' denomination suggests. Its Unidirectional full carbon construction ensures low weight and a 'stealth' aesthetic.
The Racing Quattro Carbon boasts a full UD carbon rim and 3k carbon braking surface, tipping the scales at a competitive 1,555g. Aluminium alloy hubs with an adjustable bearing system make for reliable performance in all conditions whilst Two-to-One spoke lacing on the rear wheel adds to the wheelset's strength.
Many professional and amateur cyclists around the world now use wider tyres because they offer noticeable benefits in terms of handling and rolling resistance, so the Racing Quattro Carbon has a European Tyre and Rim Technical Organisation (ETRTO) measurement of 17C (24mm external) and has been engineered to work optimally with tyres ranging in widths of 25mm to 50mm.
Where are the aerodynamic advantages, however?
When rim width more closely matches tyre width, the airflow around this system tends to be smoother than the 'lightbulb' shape of a wide tyre and narrow rim. And when it comes to lowering rolling resistance, if you can comfortably accommodate wider tyres then you can run lower tyre pressures, which is turn decreases the impact that friction has on forward motion.
