This is the saddle that we have found to work on all occasions. Originated as a Tri saddle, we view it as a Tri-Sport saddle – Road, Mountain, and Light Touring. It has that endurance kind of comfort and flexibility in positioning. This is the very same saddle used by “Antarctic Mike” Pierce in his Guiness Record 120 hours on a spin bike. Our butts agree, and this saddle would be our choice for 120 hours. Titanium rails. Length: 260mm Width: 155mm Height: 60mm Weight: 245g.
