The Powerslide frames are the pinnacle of casted frames, super strong and yet very light. These TRINITY frames are crafted from the highest quality aluminum, perfectly shaped and constructed with the lowest center of gravity in mind. These frames with their 3-point mounting system are a quantum leap for performance. Designed around the ergonomics of the wheels to provide the best stability, improved balance, reduced vibrations and maximising the power transfer in every stride. The convenient single axel system allows for fast and simple wheel maintenance. TRINITY also offers the well known X-slot mounting system which allows you to customize your boot-frame position by shifting the frame both side to side plus forwards and backwards. TRINITY isn't just the best performing mounting system for inline skates, its also compatible with ALL models across our range, so with a single Powerslide Trinity mounting boot you can enjoy all segments of skating at any time. Simply change the frames and you're ready for anything? Fitness, speed, urban, off road, hockey or even ice! This frame comes in a classic black color. 231mm. Max wheel size: 100mm
