The Ergon SMA3 Comp, intended for Trail and All-mountain riders, is a soft comfortable saddle with a slim profile that won''t get in your way. The Seating surface is flat, but slopes down in the back so you can get off and behind it easily. The Ergon SMA3 Comp is constructed with orthopedic AirCell foam and TiNox rails. Its rear side panels are made of tough abrasion-resistant material, just in case your bike ends up on its side.
