As a designer and manufacturer of high end, super lightweight bicycle components, Extralite is constantly refining and improving their designs. This is evident in their latest line of Cyber road hubs, where great care has obviously been taken to implement minor improvements to make an already stellar product even better. The CyberFront SL, as a successor to the UltraFront SX, is a single gram lighter and carries some minor improvements over the previous generation; namely, the addition of wrench flats to the bearing preload micro-tuner to allow for easier adjustment.
At a mere 48 grams, the CyberFront is the go-to front hub for the climber's wheel. Of the few hubs that are lighter than this, none can boast the simple, reliable function and gorgeous execution of Extralite's offering. The self-aligning spoke flanges are manufactured from specially-treated 7075 aluminum to handle to unique stresses of radially laced wheels. These flanges are widely spaced for optimal lateral stiffness of the complete wheel. The CyberFront features a stiff 14mm aluminum axle fitted with common-sized 6801 bearings. As with all Extralite products, the finish work on the hub shell, flanges, and axle is immaculate.
The CyberFront SL features an easily adjustable bearing preload micro-tuner fitted with 17mm wrench flats. This micro-tuner may be adjusted by hand, or with a 17mm box-end or cone wrench. It is imperative that the micro tuner be properly adjusted to avoid damage to the bearings, axle, or the micro tuner itself. Due to the nature of this system, the hub is directional and must be oriented correctly in the fork. The hub shell is marked to indicate proper orientation.
Extralite products are 100% designed and manufactured in Italy.
