Full Carbon Fiber Road / MTB Saddle Saddle uniquely shaped dimpled seating area for comfort. All carbon fiber construction super light at 103g. Rails have rubber isolators in the rear to absorb shock, and they work good. Recently bought from AliExpress. Barely used for 3 rides. The dimple seating area was comfortable, but seat overall didn't work out for my body shape. Bought for $162, now $80. Great price to try out this saddle. Long time Pricetronic user since 1999, buy with confidence.
