Extralite BlackLock Rear Thru Axle

Is This it? #01
In Stock Reminder

Product Description

For complete sizing details on all of our thru axles please look HERE  

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.


Each Black Lock skewer is simply installed like your typical OEM skewer, using a 6 mm allen wrench at a torque rating of 10 Nm. It is highly recommended that threads are greased prior to installation to ensure a proper torque rating.
