The Endless Arc ES Trinity Frame is a precision machined, multi-setup 5-wheel frame specifically designed for skaters with larger foot sizes seeking the highest level of performance for expressive flatland styles that rely heavily upon precise edge transitions and ninja-like swivel moves. Through a meticulous development and testing process we have engineered a frame that we believe delivers an innovative level of 5-wheel performance for all TRINITY mount boots. An exceptionally rigid structural design brings new levels of responsiveness, speed, and acceleration that enhance the execution of moves and open up limitless skating expression...and most importantly, fun!
For the best skating performance and movement tempo, our 5-wheel frames should be chosen based on boot size as noted on the Features tab.
