621 ERGOLUX® active 2.1SQlab’s City and Comfort saddle gets an all-round update: from an improved, lighter shell, over an increased adjustment range, to a completely newly developed technology for the Comfort active system, which is now adjustable via a switch function. New are also integrated threads for the mounting bags. The new 621 ERGOLUX® active 2.1 offers even more comfort with the same level of relief and a narrower saddle nose for more legroom.ERGOLUX® More comfort- Less pressure The wave-shaped elevation of the ERGOLUX® saddles, stretching from the rear to the front, perfectly matches the shape of the mostly bulbous ischial branches. The enlarged, less punctual contact surface, ensures the best possible pressure distribution.The first step provides rearward support and ensures improved power transmission to the pedal. The second step optimally supports the ischial branches and distributes the pressure evenly. Due to the lowered saddle nose, the perineal and front area of the pubic bone and pubic arch have more free space. active- Saddle technology comfort The proven SQlab active system allows the saddle to follow the pedaling movement, which increases the comfort, relieves the intervertebral discs and reduces the pressure on the sit bones. The active movement can be regulated via the new switch function, in two settings.
