Frequently Asked Questions

• What is unique about Ergon's Core System and BASF Infinergy® E‑TPU foam?

  Ergon's Core System uses a floating CORE of BASF Infinergy® E‑TPU inside a TwinShell construction to create three‑dimensional flexibility and damping; the result is high shock absorption with fast rebound that isolates road and trail vibrations. That 3D movement actively redistributes sit‑bone pressure with each pedal stroke and supports natural pelvic motion for improved comfort and power transfer.
• How does the SM E‑Mountain Core Prime compare to a Core 3D trail saddle?

  The SM E‑Mountain Core Prime is tuned specifically for e‑MTB use—its Core damping and shell geometry handle higher speeds, added motor torque, and extended vibration—whereas Core 3D trail variants prioritize lighter weight and a slightly more performance‑oriented shape for aggressive trail and XC riders. Choose the Prime for e‑MTB and heavier‑duty damping needs, and a Core 3D trail model if you want a more race/weight‑focused trail saddle.
• How do I pick the right Ergon saddle size and model for my riding?

  Measure your sit‑bone width and use Ergon’s sizing guidance to select the appropriate saddle width and the anatomically tailored male or female version, then match the model to your discipline (e.g., Core 3D for XC/trail, SM E‑Mountain Core Prime for e‑MTB). Also consider riding position and your body weight—Ergon recommends up to about 220 lbs for optimal Core material function.
• Are GXR All‑Mountain Grips appropriate for aggressive trail and downhill riding?

  Yes, GXR All‑Mountain Grips are built for XC through downhill with an AirCell rubber compound that provides tuned damping, a textured surface for grip in wet or rough conditions, and an ergonomic profile that minimizes ulnar‑nerve pressure for better control. At ~90 grams per pair (small with endplugs) they balance low weight with performance damping, and are 100% made in Germany.
