Feature Tour
The Catalyst Difference
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.
Offset Axle Plate
The Catalyst 4 series axle is mounted 1 1/2" 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.
Front Frame Styles
Catalyst 4 & 4C offer the option of a swing away front end featuring our patented footrests or 70° or 80° fixed frames. The swing away hangers come in 4 bends (60°, 70°, 80° & 90°) are light and easy to use and so strong we offer a lifetime warranty.
Spoke
Ki standard spoke uses 30 radial spokes to provide a stiff and durable wheel.
Maxx Mag
Exclusive to Ki, the magnesium Maxx Mag wheel creates a sleek, modernized look while providing greater stiffness and lower weight than classic nylon composite mag wheels.
Maxx Mag wheels are available in 20”, 22” and 24”.
