The Vortex V3 2.0 Frame Sliders are a revolution in safety for your bike. Not only are the molded impact pucks formed from a special energy-absorbing material, the 2.0 Frame Sliders also feature Vortex's Controlled Flexion Areas. These specially designed flex points are meant to bend in the event of an extreme impact instead of transferring that energy to the bike, sacrificing themselves in a last ditch effort to prevent catastrophic damage to your frame.
