Fi'zi:k Thar Manganese Saddle. If you've got a 29er mountain bike then Fi'zi:k has created the perfect saddle for you. The Fi'zi:k Thar Manganese saddle is optimized for the demands of a 29er's geometry. Fi'zi:k sat down and looked at how Mountain Bike riders actually sit on a 29er and the result is a saddle with longer rails and a relatively stubby nose a design that allows the rider to compensate for the weight distribution of 29er frames and create a well balanced ride that won't make you fight to keep the front wheel on the ground. Craftsmanship is as superb as usual as the Thar features a synthetic Microtex cover, carbon reinforced nylon shell, as well as Manganese rails for superb performance.
