Fizik's Antares VS X Kium Saddle is an extra supportive and even more comfortable rendition of the popular Antares. At 140 mm wide and 275 mm long, the Antares VS is wide enough to fit most sit bones and has an average length. What makes the Versus X saddle so special however is the depression in the padding running the length of the saddle. Compared to the VS, which has a seven millimeter deep groove, the VS X digs out a full twenty millimeters of pressure relief, which ensures that the channel won't flatten out if you happen to have an extra sensitive perineum. This effectively reduces numbness inducing pressure on long rides. Better than a saddle with a hole in it, the Antares VS X focuses pressure to the sit bones and decreases it where you don't want it. Kium alloy rails provide a titanium like ride quality without ti price. Fizik's wallet friendly carbon injected nylon base supports low density padding, covered with a seam free microtex cover.
