There's definitely a noticeable difference in the widths. If you're normally on 143, a 143 power would be what I'd go for. I only ride 143 powers on my bikes and have tried a 155 that I got cheap in the past but it gave me discomfort and rubbed my legs
Provisional dibs on the saddle please
Just need to double check sizing
Edit: I’ll ask here
I’ve always used a 143mm normal saddle. Romin and Toupe have been my go to for years.
I’ve never used a power saddle. Am I right in thinking the 155mm saddle is the one to go for? Is there an element of sizing up?
I sat on an Arse-o-meter thing in a bike shop years ago and it put me on a 143 saddle. But I don’t remember what my sit bones actually measured.
