The Trinity Power XXX skate frame for 4x110mm wheels is a 3-point mounted frame. This 3-point mounting allows for a lower centre of gravity, with more stability and better power transfer.
The triple-X design ensures a strong and very stiff construction - the "x" construction is found integrated into the three-dimensional design inside the frame: In the longitudinal profile, in the side walls, and on the bridges. This is done to really deliver on big on each of your power transfers.
