I purchased this Qu-ax Air Saddle for $40 (U.S.) and rode it about 50 feet (15.2 meters). The curvature is not for me, but you might like it. Here is a link to saddle on the Qu-ax website: http://www.goudurix.com/us/quax-air-saddle.html The only disadvantage is that it secures to the seat post using the rail system. I’ll take the best offer.
