It took an incredible amount of time, effort, research, and design but we did it! The POWERSLIDE Core collection of frames is the most thought-out and capable family of frames in inline speed and racing history. The POWERSLIDE Core 125 - 12.5 TRI frame is a great option for serious inline racers looking for supreme performance. Inspired by Formula 1 racing, this high-performance frame incorporates revolutionary aerodynamics that allows wheels to spin faster while expelling turbulent air. Able to stand up to the demands of big wheel triskate racing, the frame is made of lightweight, rigid, and durable CNC machined high-grade aluminum. To deliver inline racers unmatched performance the POWERSLIDE Core 125 - 12.5 TRI frame incorporates the famous TRINITY 3-point mounting system. Ideal for big-wheel setups, the TRINITY system mounts to the boot with three points of contact, creating a channel that brings your wheels as close to the boot as possibl in order to provide a low center of gravity that gives you improved stability, and efficient power transfer. This innovative frame is also compatible with POWERSLIDE’s pitch and stride control system which corrects physical malpositions and optimizes performance. For high-end triskate (3-wheel skate) performance give the POWERSLIDE Core 125 - 12.5 TRI frame a try.
