Dynafit Blacklight brake is light ski stopper for retrofitting. Compatible with the Blacklight binding. Important: After mounting the brake, the release value of the binding must be checked by an authorized professional with the appropriate measurement device and, if needed, readjusted. Settings are not only based on binding and boot types, but are also on additional components such as ski brakes. Mounting and adjustments done by unauthorized personnel are at the risk of the user and may lead to termination of the warranty. An improper setting can increase the risk of injury.
