The MD Line stands for maximum relief of sensitive areas and so the 621 MD® active 2.1 offers the optimal pressure distribution according to medical criteria for city bikes with a slightly forward-leaning to very upright sitting position. At 85%, this model has the highest relief for the perineum and prostate of the entire SQlab product range.
To be on the safe side, talk to your doctor.

The 621 MD active 2.1 has an improved, lighter saddle shell, a larger adjustment range and the completely newly developed technology for the Comfort active system, which can now be adjusted using a switch function. The option to attach bags is also new. The new 621 MD offers more comfort with the same level of relief and a slightly narrower saddle nose.
