The VX has the performance you have come to expect from a Catalyst, with a little bit less adjustment of the axle plate and few less options.  Weighing in at 23lbs and constructed from ultra-lightweight 7000 series aluminum, the Catalyst 5 is arguably the best choice in high-performance folding wheelchairs. With our largest selection of options to help you customize and configure your chair, the Catalyst 5 makes daily life easier, no matter what the day brings.
