This saddle offers comfort, together with increased stability for faster bike splits

After working with world time trial champion Fabian Cancellara to create the Evo TRI 40, we aren’t surprised that Prologo have produced a fantastic saddle for a fast bike split.


Raised polymer ridges attached to the firm but deeply padded nose of the TRI 40 are designed to provide enough traction to prevent the slide out of position that many riders experience when riding hard on the aero bars.

Despite keeping the rider firmly in position, the ridges never caused irritation, though they were noticeable during the first few rides.

Whether in an aggressive tuck or sat upright, the variation in padding density and thickness keeps the saddle supportive and comfortable for those who prefer narrow designs.


Tubular titanium rails, together with a carbon-reinforced nylon base, keep weight competitive at 222g, but it’s the innovative solution to bum-sliding that sets this perch apart.
