power saddle specialized 143 or 155mm version?

[dedobike]

They are undecided on the width of the specialized power saddle.
My width of sit bones is 121mm which version should I take? 143 or 155mm?

Based on Specialized chart you can use both so it probably depends on what position you are using, more aero or more upright?

But I knew that for the saddle power is another scheme that suggests to take a size more than a classic saddle for example if you use a romin 143mm you have to choose a power 155

Could be, I couldn't find any charts that include the power saddle, but maybe you could ask a specialized dealer about that.

I had both on two bikes with no problems(S-Works).
