At 155mm the Trinity offers wider sit area and a slightly more padded Sit Area. The "V" section is wider and deeper than other 3 West saddles. We lowered the contact point of the mid saddle and widened the Comfort Surface Pad. Now Soft Tissue and the Perineum touch after nearly 1 inch of drop. The Trinity has black hollow titanium alloy rails, a moisture resistant cover and a foam membrane that provides the basis for our Comfort Surface. The saddle also features 25mm of area between the rail and shell. Overall weight 254g.
