4ZA FAST ForkThe state of the art 4ZA Fast fork brings bicycle aerodynamics to a new level. Our

main goal being to reduce the drag generated by a spinning wheel and to eliminate

turbulence from the front brake.

Both of these problems are a thing of the past, when using the wind-cheating 4ZA

Fast fork. By integrating the front brake in the rear leg of the Split-fork, the brake is

not only shielded from the wind, it also increases the performance of the Split-fork

since the drag is now neutralized from axle to fork crown.

SADDLE GUIDE

4ZA offers a complete line of high performance yet comfortable saddles.

Thorough testing has shown that pressure distribution and movement on the saddle are crucial to

ensure a comfortable position. Our objective is to design and develop saddles that offer comfort and

support while riding on the “hoods” (hands on top of the bars) as well as riding on the “drops” (in the

most aerodynamic position; the rounded part of the bars). This should be true regardless of the type

of bike one is riding (Road, Cyclocross, Triathlon, Mountain Bike or Hybrid). The key to this is to make

the sit bones relieve the pressure and friction from the genital (soft tissue) area.

4ZA SADDLE WIDTHS

Due to the variation in a rider’s weight and the distance between the sit-bones, 4ZA offers Men’s

saddles in 2 widths (130mm and 145mm) in all our models (Stratos, Cirrus and Cirrus Pro). The correct

width of saddle for one’s body type will result in a more effi cient and comfortable pedal stroke, while

the wrong size can adversely affect the pedal stroke.

A SIMPLE GUIDELINE

Tall people often have a bigger distance between the sit bones, thus a wider saddle can distribute the

weight over a bigger area, reducing pressure to the soft tissue.
