Numbness occurs as nerves are compressed and/or are receiving reduced blood flow in the perineum area. The corresponding body part cannot be felt correctly and is perceived as numb.

Attention! Special nerve fibers and vessels in the perineum area of the male are respon - sible for erection of the penis. A reduction of sexual performance can be a result of these parts, repeatedly and for long periods, receiving low blood flow or being often compressed.

This process is reversible. After a long rest familiar sexual performance reappears.

Attention! The problem can become chronic. Numbness is a sign for concern! Listen to your body. The positives of proper bicycle training outweigh the negatives.

 Studies on bicycle seats

	Typical pressure measurement image of an arched classical saddle with very heavy pressure at the perineum area. The blood supply is significantly reduced. Attention! These saddles are probably being viewed as comparable during a test ride. The seat bones react to pressure with pain, while the perineum area does not react very much!
	Typical pressure measurement image of a saddle with a hole with dangerous pressure peaks at the sides of the perineum area, in important arteries and in nerve tracts. The blood flows well in the middle, however, numbness is experienced.
	Typical pressure measurement image of a SQlab step saddle with clear pressure points at the seat bones and pressure relief in the lowered frontal area. The depression in the middle of the saddle guarantees an outstanding blood and nerve supply. Urologists recommend SQlab step saddles.

Solution:

Measure seat bones to prevent selection of a saddle that is too narrow.

The SQlab step saddle concept distributes body weight in accordance with medical advice. The seat bones accept the majority of the body weight on a maximized area. The pressure points on the perineum area and pubic bones are evenly relieved.

General tips for numbness:

• Select a more upright sitting position
• Ride standing up
• Do not ride with a heavy backpack
• Increased pedal pressure relieves the pressure on the saddle
• Reduced body weight reduces pressure on the saddle
• Use thinner seat padding
• Sit as far back as possible at the widest area of the saddle
• Slope the saddle a little forward/downward
• Optimize geometry (SQlab recommends body scanning CRM)
