SQlabs first gravity and enduro specific saddle. It's different to the other Ergowave saddles in 3 ways. While still maintaining the comfort and skeletal support that all the SQlab saddles are known for. It has a 46mm flattened and longer nose It has 12mm of padding that helps with comfort and shock absorbption Kevlar reinforced sides and grip material on the top rear section of the saddle 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. When you are on the rivet the 60X is really comfortable Standard on the 60X is the already proven and comfy Active system. It acts like micro-suspension and it also allows 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: 280mm Weight: 280g (130mm) Rails: Round S-tube Suitable for MTB Gravity and Enduro Active System (Soft, Medium and Hard tuneable) Unisex
