TiLite builds the 2GX with one-piece side frames, the same as rigid chairs. Other manufacturers build their folding chairs by bolting together with two- or three-piece side frames, leading to flex, squeaks and loss of energy. One-piece side frames increase performance by reducing flex and increasing durability. The 2GX features TiLite’s Tru-Fit System. With the Tru-Fit System, TiLite precisely clamps all major components onto the side frames. Other manufacturers attach components by bolting through the side frames. The Tru-Fit System eliminates one of the main stress points on today’s wheelchairs by reducing the number of holes in the frame by 50%, and it allows for infinite adjustability.
