"NICOLAI have also created a geometry concept that they’ve dubbed GEOLUTION, which is reputed to combine improved climbing capacity with increased comfort and even better handling on descents. In pursuit of the ultimate weight distribution for climbs, the EBOXX 3 models with their GEOLUTION geometry feature a notably steep 77º seat angle and long 470 mm chainstays. To keep the bike stable on descents, they’ve gone for a slack 63.5º head angle, short 45 mm stem and long frame (662 mm top tube in a size L). If you prefer to keep to convention, then NICOLAI have reserved classic geometry for the ION-16-Classic-EBOXX.'
