Ergon has reinvented the way bicycle saddles support the rider, separating the hard supporting shell that connects to the rails from the padded shape that you sit on. The new Ergon ST Core Ultra sandwiches a layer of Infinergy, a thermoplastic polyurethane foam, between two shells. The lower shell attaches to the rails and is rigid. The upper shell has the covering and flexes with the rider. Between them is the new composite, developed in partnership with BASF, that uses the same highly resilient and elastic foam technology found in today’s popular running shoes…
The use of Infinergy allowed them to bring the concept to a useable, production part. It holds up to repeated and constant pressure, springing back to its original shape. It also allows the upper to move with the rider, improving overall comfort and reducing vibration.
The saddle makes its official debut at Eurobike in men’s (shown) and women’s versions. Other features include a central relief channel and metal rails. The shape mirrors their fitness and comfort saddles, so our guess is that’s where this one’s positioned, but could be a nice option for cobbles and gravel, too.
UPDATE: It’ll be available in S/M (9-12 cm) and M/L (12-16 cm) with an MSRP of $149.95. Available early 2018.
