With the rising popularity of thru axle designs being used by nearly every major fork and frame manufacturer, companies like Extralite have immediately filled in the niche for quality performance tuned parts that many discerning cyclists desire. With this in mind, Extralite has produced the Black Lock, a surprisingly lightweight thru axle skewer. Utilizing a unique externally tapered surface and precise dimensioning, Extralite is capable of shaving as many grams as possible while still maintaining a sturdy design that’s tough enough to withstand the abuse of a typical mountain bike ride. To ensure proper installation that’s as smooth as possible, each Black Lock comes with a self lubricating brass washer that is designed to reduce friction between the skewer and frame/fork.
The Extralite Black Lock is available in configurations to fit most modern forks:
