This wheelset is perfect for Road and Gravel racing and Cyclocross Super Stiff, Durable and Rolls Extremely Fast. Featuring full high-tensile TC35 carbon rim construction, which has been optimised to provide exceptional stiffness and durability for use with disc brakes. Fast Forward has equipped this wheelset with DT 240 centrelock hubs, which deliver exceptional rolling efficiency and are a fantastic foundation for this all-rounder wheelset. These hubs provide superior stability and rolling performance while being super-easy to maintain and service when the time comes to do so. Thanks to the closed bearing seal design, these hubs are protected from the elements for a long time.A Road Wheelset Designed for Riding Anywhere. This wheelset is designed to fulfil most of the road cyclist’s requirements with elegance and superb, reliable performance. The 45mm rim height has been aerodynamically optimised thanks to the DARC profile, which although being super-stiff and flex-free also delivers exceptional comfort and is very responsive. If you desire a long-lasting, high-performing wheelset that has style and can be ridden virtually anywhere, the F4D Full Carbon Clincher is for you Features: Material: Rim: High Tensile TC35 Carbon; Hubs: Aluminium; Spokes: Stainless Steel; Nipples: Brass Rim Depth: 45mm Rim Width: 22 4mm Rim Type: Full Carbon Clincher Max Inflation Pressure: 130 psi Rim Technology: DARC Profile Spoke Type: DT Aerolite Spoke Count: 24H front and rear Nipples: DT ProLock Hub Model: DT Swiss 240 Centrelock Freehub: Shimano 10, 11-Speed Weight: 1.53kgTechnologies: DARC: DARC technology is short for ‘Double Arc’ which refers to the profile of the rim. The revolutionary DARC profile improves aerodynamics dramatically by reducing the drag. Air has the characteristic to stick to its surface and by creating a negative arc section the air will be compressed more at the positive section. This will increase the pressure just like on the topside of an airfoil. Increased pressure results in a faster airflow and less resistance on the wheel which reduces the drag and increases the speed. Carbon TC-35: The Carbon TC35 is a material characterised by its high strength. This is important in a wheel to add durability and an extra level of stiffness to the wheels which makes them easier to turn. The wheels are therefore super robust and superior to other wheels made of other kinds of carbon. This level of durability makes them highly capable at being used in a variety of different environments. DT Swiss Hub Technology: DT Swiss hubs have earned their legendary reputation for quality and performance. There are multiple features that make this hub design a winner: The Ratchet System driver mechanism is extremely durable, reliable and can be serviced without special tools in minutes, thanks to its simple press fit assembly. The press fit assembly also allows all hubs to work in almost any currently existing axle configuration, making them compatible with almost every bike. The contact free seals and high precision build guarantee smooth bearings; every bit of the rider’s energy is transformed into forward momentum. These features and the super lightweight design of all the hub parts highlight the racing legacy of this classic hub. DT Swiss ProLock: DT Pro Lock nipples prevent the spoke-nipple connection from loosening. This patented locking system is based on a special pre-applied dual compound adhesive, which coats the nipple threads. As soon as the nipples are twisted, the dual compound adhesive starts to react and is completely hardened after 6-7 hours. Internal tests show that the reliability and durability of a wheel built with DT Pro Lock nipples are increased up to twenty times compared with the use of standard nipples Buy Fast Forward Wheels & Tyres from Chain Reaction Cycles, the World’s Largest Online Bike Store.
