Saddles

4ZA engineers and designer s are passionate cy clists. They

know how important the support of the saddle is during long

rides. Starting from scratch, our design team went back to the

3 basics of what makes a great saddle. The result is a focused

line of seats providing the right solution for your specifi c body.

Enough variations to fi nd the right fi t but not so many that you

get overwhelmed by the decision process.

– Eliminate Saddle Sores

– Maintain Comfort in Multiple Seating Positions

– Give Your Legs Freedom of Movement

4ZA SADDLE WIDTHS

Due to the v ariation in a rider’ s weight and the distanc e

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 f or one’s body type

will result in a mor e effi cient and comfortable pedal stroke,

while the wrong size can adversely affect the pedal stroke.
