Fly away: with ST Core saddle by Ergon

There have been no significant changes to bicycle saddle technology since the 1960s, with most models conforming to a standardized principle: rails – saddle shell – padding – cover. The disadvantage of this construction is that the saddle shell has a dual role: it bears the load of the cyclist and is simultaneously the seat shell, being the substructure for the padding. The result is a stiff seat shell, which restricts seating comfort.
Ergon’s research team decided to focus on this aspect in particular, which led to the development of the revolutionary TwinShell technology with an ergonomic core. Two shells work isolated from each other in a sandwich construction, holding a floating arrangement consisting of a high-performance elastomer damper. The material is an expanded thermoplastic polyurethane (E-TPU) developed by BASF. The lower supporting shell performs a load-bearing function, while the upper flexible seat shell supports the padding. This design principle not only increases comfort but also allows for an entirely new form of pedaling ergonomics.
