Catalyst 4 & 4C


Catalyst 4 & 4C both take advantage of all of the "Catalyst Difference" design features to allow you to fit adjust and ride with confidence. A defining characteristic of each chair is its axle plate which we will highlight below.

Innovative and Patented Frame Design
Patented frame concept uses intelligent geometry to create a significantly stronger lighter and better performing chair.

Offset Axle Plate
The Catalyst 4 series axle is mounted 1 " forward to traditional axle positions. This small change can improve efficiency significantly. The simple axle plate design offers vertical adjustments of the axle in five positions. It can also be reversed to gain greater rearward stability.

Swing away footrests
Enjoy the simplicity and strength of Catalysts patented swing-away footrest hangers. The tapered engagement keeps the footrests snug and rattle free. Comeswith a lifetime warranty.
