Technology Engineered to Empower. Titanium The TiLite 2GX is hand crafted from seamless, aerospace-grade titanium. Why titanium? Because titanium has no equal when it comes to dampening vibrations caused by riding over rough or uneven surfaces. This means superior comfort for the user during many hours of use. Because titaniums weight is about one-half that of the aluminum used in most wheelchairs. This means that a completely assembled 2GX is more than 15% lighter than its aluminum sibling, the Aero X. Because titanium is incredibly strong. This means the 2GX will shake off years of abuse. One-Piece Side Frames TiLite builds the 2GX with one-piece side frames. We also build our rigid chairs with one-piece side frames. Other manufacturers build their folding chairs with two- or three-piece side frames that are bolted together, leading to flex, squeaks and loss of energy. One-piece side frames increase performance by reducing flex and increasing durability.
