The 610 Ergolux is for mountain or trekking use - It gets a bit more padding than the 611 and 612 models, but still offers that comfortable unique raised section for perfect platform for your sit bones. The two staged wave shape is a little more emphasised which works wonders when sitting in a more upright position and carrying a back pack. Ideal for mountain and gravel use - and it's also available in the Active version You'll notice there is no cutout - what about my gooch you say? The dropped mid and nose section almost completely eliminates perinium pressure while the rear section naturally supports your sit-bones and the skeletal structure not soft tissue. The 60X also has an extra stepped mid-section, more pronounced than than the 611 and 612 - This provides loads of comfort and more positioning options riding up steep tech terrain. The Active system. It acts like leaf springs on your car, allowing very subtle pelvic rocking which helps reduce pressure on spinal discs and accounts for muscular imbalance or leg length discrepancies - In other words, it just works darn good. A new and refined shape developed in collaboration with the University Hospital of Frankfurt and Frankfurt University. A specially designed shape works in unison with the human skeletal system allowing less gooch pressure and higher power outputs. Rather than a cutout running full length of the saddle which creates pressure spots the SQlab supports your sitbones while allowing up to 65% pressure relief. How do I know what size I need? Before purchasing a SQlab saddle you can order a free home fit kit to determine which saddle size you require. It will take into account your sit bone distance (the part where you contact the saddle) and also your style of riding which determines the degree of hip rotation. How does sizing work? Once you have your sit bones accurately measured you'll need to add 0, 1, 2,3 or 4cms to the sit bones measurement depending on your riding position. A more upright positions will add width. The more dynamic the riding position the more hip rotation and hence the narrower the contacting part of your sit bones and hence a narrower saddle will provide the correct fit. This works the same whether you are male or female Width: 130, 140, 150, 160mm Length: 275mm Weight: 245g (130mm) Rails: Round CrMo Suitable for MTB, Gravel Touring Active System (tSoft, Medium and Hard tuneable) Unisex - Due to the sit bone measurement and the step saddle concept, it is not necessary to differentiate between men and women
