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 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.  Thanks to the proven SQlab active system which allows the saddle to follow the pedaling movements of the rider, comfort is increased, less strain is placed on the inter- vertebral discs and pressure on the sitbones is further reduced. The flex and active movement can be adjusted to the body weight with the comfort sticks in the active dampener.  Exception 621 City/ Comfort Series The following special regulations apply to saddles of the 621 Comfort model range: Sit bone distance less than or equal to 12 cm >> Saddle width 18 cm Sit bone distance greater than 12 cm >> Saddle width 21 / 24 cm Available in saddle widths 18, 21 & 24 cm.
