Interesting. I have the Romin Mirror and Power Mirror after having tried the Power Arc and liking the fit. I do think the Mirrors are the best saddles I’ve tried.
The Power Mirror still gives me a little bit of upper hamstring rub. It’s not as bad as the regular Power though and it’s livable so far. I also have more numbness issues with the Power Mirror vs. the Romin Mirror. It takes some trial and error to get the nose set correctly on the Power so that I don’t get numbness, but also don’t start sliding forward and putting too much pressure on my hands, but once I find the right position, it’s mostly a non-issue, but I’ve never experienced not feeling the nose on my junk.
The Romin Mirror I liked as I don’t have any numbness issues and the upper hamstring rub is gone. I thought it would be my Golidlocks saddle. However, I feel much more stable on the Power Mirror. Outside, I felt okay on the Romin Mirror, but once I hopped on the trainer, I couldn’t stand it for very long. I put the Power back on and felt the immediate difference in stability. I might be riding too far forward on the Mirror, perhaps, but appreciate the wider base that the Power gives me and it makes the trainer and long rides more tolerable.
