Ultima 155mm Bike Saddle

Maximum Comfort for Upright Riding Positions ULTIMA is engineered for riders who prioritize comfort without sacrificing performance. Featuring an enhanced volume of ZETA's patented Reactive Padding™ and a 155mm width Ultima delivers exceptional protection for sit bones and soft tissue—perfect for upright riding positions, long-distance touring, and riders who need extra support. Why Riders Choose Ultima Enhanced Reactive Padding™ Volume – Maximum protection for sit bones, soft tissue, and the sensitive perineal region without the bulk of traditional comfort saddles 155mm Width – Wider platform distributes pressure across a larger surface area, ideal for upright positions and riders with wider sit bones Surprisingly Lightweight – At 302 grams, Ultima is significantly lighter than comparable comfort saddles while delivering superior cushioning Versatile Performance – Excels on commuter bikes, e-bikes, touring setups, mountain bikes with upright positions, spin bikes, and recreational road riding Comfort Without Compromise Traditional comfort saddles achieve cushioning through excessive padding—which compresses over time, creates friction, and adds unnecessary weight. Ultima's Reactive Padding™ technology provides dynamic shock absorption that actually responds to your body's movement, maintaining consistent comfort mile after mile without the drawbacks of conventional gel or foam padding. Who This Saddle Is For Ultima is built for riders in more upright positions: commuters, recreational cyclists, mountain bikers on trail and all-mountain bikes, gravel riders, touring enthusiasts, spin class regulars, and anyone who's struggled to find a truly comfortable saddle. If you've tried "comfort" saddles that felt bulky, heavy, or still caused discomfort after an hour, Ultima's physician-designed padding system will change your riding experience.
