The S-Works Power Arc saddle expands on the success of our original S-Works power saddle while featuring the same channel & length as the original. This means that it features a stiff FACT carbon fiber shell & rails & lightweight eva padding. The shape of the saddle is also designed to provide ample sit bone support & this has been coupled with a shorter-than-usual nose section to keep pressure off of soft tissue while riding in aggressive positions. We even took this ideology a step further via an extra wide & elongated body geometry channel thats been proven through blood flow testing & pressure mapping to reduce numbness & pressure on unwanted areas. & while this all seems familiar if youre already a power loyalist this iteration features a curved body geometry shape that better contours to your body. What does this mean for your ride? It means that youll feel as if youre in the saddle" not on it. & ultimately this equates to greater comfort & superior performance in all seated positions whether youre a man or woman. Patented body geometry design is lab-tested for both men & women to ensure blood flow to sensitive arteries. Stiff FACT carbon fiber shell is tuned for support & ride compliance. Super-light eva padding for comfort & support on longer rides. Ultra-light, strong, & oversized FACT carbon rails. Level 2 padding: medium density foam for bike feel with additional cushioning. Swat-compatible mounts molded into the saddle base allow for sleek & integrated storage solutions. size 155mm / weight: 145g
