FOX 2026 GLIDECORE NA3 AIR SPRING - A quick Tech Talk

10 years after the first generation negative air 'NA' system from FOX was released, Fox have now released NA3, named Glidecore. A clever new air spring designed to allow for, and disperse torsional loads. This in turn allows the air shaft movement to remain un-impeded by twisting loads that the fork can be subjected to during use. This allows the air spring to travel through its range with minimal stiction as a result of torsional stresses in the chassis of the fork, hence aiding performance. Available as an upgrade to 2021+ 36 forks. see full compatibility on site.
