Ergon designed the SM3 saddle from the ground up. The ultra-thin shell was developed using finite element method analysis to map loads and areas of stress. This gave the saddle its distinctive shape, and allowed Ergon to tune the shell for optimized deflection.
The shell has progressive dampening layers that are individual to the different saddle widths. Every size option gets its own layer for rider-specific compression. Adding to the SM3’s trail taming is a nose-mounted micro-damper. This damper, located in between the shell and rails, filters out smaller vibrations.
