When you're pushing hour six into an endurance race, 20 millimeters might not seam like a great distance. But, that's the difference between a Small and Large Ergon SM3 Pro Saddle. And when it comes down to determining long-term comfort on the trail, it's a significant factor. That's why Ergon saddles comes in three different sizes.
The German-based Ergon always places its focus on comfort, and accordingly, its first handlebar grips gained a quick cult following because of their support and ability to reduce fatigue. And when those grips took off, instead of sitting on success, Ergon expanded its offerings to include more contact components like hydration packs, gloves, and now, even saddles.
Using the same benchmark design principle, Ergon designed the SM3 saddle from the ground up. To start with, the the ultra-thin shell used an extensive finite element method analysis to map loads and areas of stress. This gives the saddle its distinctive shape, but more importantly, it allowed Ergon to tune the shell construction 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 TiNox rails, filters out smaller vibrations. The rails are hollow to reduce weight and allow 30mm of adjustment. The SM3 also has an easy-to-clean synthetic leather cover -- just wipe it off with a damp rag.
After developing the SM3, Ergon enlisted the help of the saddle perfectionists at Selle Italia for production. So, every SM3 has been made in Italy by expert craftsmen. To size yourself for an Ergon SM3 Pro Saddle, you'll need to measure the distance between your sit bones. Widths between 9-11cm should ride a Small, 11-13cm medium, and 13-15cm should opt for a Large.
The Ergon SM3 Pro Saddle is available in the colors Black and White and in the sizes Small, Medium, and Large.
