I have an Aliente- does not work for me. While it has a good shape and is wide enough in the sit bone area, the issue I have with it is that after 75 kms the nose area causes me numbness (I have it on a road bike). Other than that it is a relatively comfortable firm saddle (for me anyways). I am looking at the Vitess HP since that one apparently has a different nose, and a flex. Am about to sell it.
