Saddle Width System

perfect fit

Comfort begins with the right size. The 621 ERGOLUX® active 2.1 comes in multiple widths, ensuring that the sit bones are fully supported. Only then can pressure be effectively relieved from the sensitive perineal area in men and the often lower pubic arch in women.

M-D Line

pressure relief

The high classic step shape, combined with the maximized dip, distributes body weight to the sit bones. This model offers with 85% the highest relief for perineal area and prostate from the entire SQlab product range. The M-D Line is also suitable for heavier riders due to the active system and the stable CrMo rails. In particular, the width of 24 cm provides a very large bearing surface to absorb even high body weight well.

Back-friendly support

The SQlab active saddle technology allows the saddle to follow the natural pedaling motion through lateral flex. This can help to reduce strain on the spinal discs and promote mobility. The updated active 2.1 version now features a practical switch function – letting you choose between two levels of movement, easily adjustable in seconds.

M-D Line stands for maximum relief.

ERGOLUX® means comfort

The two-stage ERGOLUX® shape supports balanced pressure distribution between the sit bones and the perineal area – ideal for a more upright riding position. Thanks to the wave-shaped contour, pressure is spread over a wide area of the sit bones. Compared to the M-D Line, the difference in height between the seating surface and the relief zone is more moderate – for noticeable comfort on everyday city rides or leisurely tours. The 621 ERGOLUX® active 2.1 provides up to 70% relief in the perineal region.

FAQs

The 621 M-D active 2.1 uses a model-specific sizing system. For a sit bone distance of up to and including 12 cm, we recommend the 18 cm saddle width. If your sit bone distance is over 12 cm, either the 21 cm or 24 cm version may be suitable.

Sehr bequem

Passt hervorragend zu meinem City Bike.

4 out of 5 stars

Comfortable for long rides with a very upright riding posture

The depression in the middle does a good job of protecting the 'family jewels' from discomfort. My only negative observation is that my sit bones tend to slide forward so I have to reposition them frequently.

Solved sore coccyx problem

I was worried I’d be spending a lot of money and not solve the problem I had of a sore coccyx, but I’m so glad I bought this. Cycling is comfortable again. I cycle about 1hr a day for my commute on a Pointer city bike.

Good

I have this on my 1991 Cannondale Bicycle touring.
