Main difference between Fabric Tri Flat Saddle and Fabric Tri Flat Carbon Saddle in a rails , in the carbon version they made out of carbon . on my opinion I'd prefer actual saddle shell ... I was not aware of it so wanted to make it clear here. Overall it is a good saddle I have both Carbon and non Carbon one
I have been searching for a triathlon saddle for a couple of years. Tried Specialized Sitero, Bontrager Hilo, Pro Aerofuel II. So far I really like this Fabric Tri saddle, it's comfortable both in and out of aerobar. Used it recently on a metric century with about 2000 ft of climbing, and it felt good the whole time. The integrated bottle mount is great and can be easily swap out.
