This knowledge is the drivingforce behind all Body Geometry products but when itcomes to saddles thereÂ’s one crucial addition to theequation:BLOOD FLOW. For years weÂ’ve been workingwith medical doctors engineers pro athletes andour Body Geometry Fit professors to develop anextensive line of market-leading saddles that improveblood flow & relieve soft tissue pressure.A TRIATHLON-SPECIFIC SADDLEhas been on our radarfor a while & presented its own set of challengesto our development team. Put simply triathletes sitdifferently to road riders on their bikes. As they getinto the aero position they shift their weight forwardonto the extension of the sit bones called the Pubic Rami. A different sit zone means different pressurepoints & when youÂ’re in the aero position forhours thatÂ’s a whole lot of soft-tissue pressure anddiscomfort. Our new triathlon specific saddle Â- the Sitero -incorporates a Sit Zone that provides support on ariderÂ’s bone structure in the aero position. The Sit Zone allows the pelvis to rotate farther forward whichtranslates to MORE POWER FROM THE GLUTES & A MOREOPEN HIP ANGLE.COMPATIBLE WITH 9MM SADDLE CLAMPS ONLY27114-1600
