The Powerslide TRINITY adapter converts skates feat. a regular 2-point mounting standard into a skate with TRINITY 3-point mounting. The only requirement is that your current skate has a shaped outsole with a 9-13mm heel pitch - means the outsole is not flat but has a higher heel. The adapter could be used for example for USD Sway skates but also skates from other Brands with a similarly shaped outsole like the Sway. Take advantage of our patented and proven TRINITY system which provides a superior power transfer, reduces fatigue, and improves control and stability.
