Say goodbye to pressure, numbness, and post-ride soreness — and hello to all-day comfort on hybrid, comfort, and touring bikes. Engineered for both men and women, the new ST Core Evo takes long-distance riding to a whole new level. At the heart of the saddle is our floating TwinShell design with CORE 3D® technology. This innovative construction supports your natural pelvic movement while pedaling, actively relieves your sit bones, and smooths out harsh bumps from rough roads and trails.
CORE 3D® uses next-generation E-TPU material — the same type of advanced tech found in high-performance running shoes — to deliver responsive cushioning, outstanding damping, and long-lasting durability. The anatomically optimized seating area has been fine-tuned for male and female riders through extensive lab research and real-world field testing. A pronounced relief channel helps effectively prevent numbness and pain, even on epic days in the saddle. Result: a saddle precisely tailored to the needs of comfort and e-bike riders around the world — ready to turn every ride into a smooth, supported, and genuinely enjoyable experience.

    Not as good for me as I hoped (2)

    I measured my sit bone width (121mm) and according to Ergon's Saddle Selector a M/L was my proper size. I think I would have been better off with a S/M

    Not As Good For Me As I Hoped

    After riding for 50 miles I decided to go back to my Selle SMP TRK for my main bike, but I'll put this on the bike that I don't ride as often.

    ST Core for more upright posture and treating pudendal neuralgia

    The ST Core saddle allowed me to get back on the bike again provinding support for my sit bones on a more upright posture and thus alleviating pressure in the soft tissue. I will move on to an SF Sport Gel Saddle in a couple of months. Thank you ERGON

    Very interesting and comfortable, but not a game changer.

    The extra compliance provided by the dual density foam initially felt a bit like having a flat rear tire. There was a significant amount more float and shock absorption through the saddle. That said, I wasn't blown away for the price. An improvement over other saddles I've tried, but no silver bullet.
