Did you already measure your sitbones?

A prerequisite for maximum comfort and relief is the coordinated saddle width, so that it is guaranteed that your seat bones lie completely on the saddle. This is the only way to properly relieve the sensitive perineal area in men and the usually lower pubic arch in women. Available widths: 18 / 21 / 24 cm

Perfect grip 

The raised rear results in more grip toward the rear and provides more efficient force transfer.

Comfortable sitting position

 The dual waves make the supporting surface significantly larger than before, keeping the sit bones from sinking less deeply into the seating area. the 621 ERGOLUX® offers more volume in the upholstery, so the foam can become slightly softer. 

Lower saddle nose

The lower-lying saddle nose accordingly presses less on sensitive positions. Equally so for both men and women.

Infinergy® damper

The proven SQlab active saddle technology follows the pedalling movement, comfort is increased, the intervertebral discs are protected and the pressure on the seat bones is reduced. The damper is made of the well-known Infinergy® material from BASF, which has proven itself in running shoes.

Description at a glance

The 621 ERGOLUX® active 2.0, the proven City and Comfort saddle, will appear in 2019 in a new design. Compared to the firmer performance ERGOWAVE® models, the 621 ERGOLUX® active 2.0 offers greater padding volume which makes for softer feeling foam. The dual waves make the supporting surface significantly larger than before, keeping the sit bones from sinking less deeply into the seating area. As a result, the ERGOLUX® does not have the disadvantages that normally come with softer foam.

The Models 602 ERGOLUX® 2.0 and 621 ERGOLUX® 2.0 will be delivered with the Infinergy® damper. This shock absorber is made of BASF's Infinergy® material, which has proven very successful in running shoes. This E-TPU offers improved low-weight cushioning and durability. The damper comes in a new modified form and allows significantly more active movement in the SQlab saddles.

The first level accommodates the rear part of the sit bones offering perfect support for improved force transmission onto the pedal. The second level ideally accommodates the unburdened ischial rami, thereby ensuring the best-possible pressure distribution. Due to the saddle nose sitting lower, the perineal and front area of the pubic bone and pubic arch have more free space. Thanks to the proven SQlab active system which allows the saddle to follow the pedalling movements of the rider, comfort is increased, less strain is placed on the inter- vertebral discs and pressure on the sit bones is further reduced.
