The more I ride it, the more I like mine. I have not done any rides longer than an hour and a half, but I had no soreness or other issues after that ride and it included a decent climb on a gravel road. Shorts slide around easily on the smooth surface (no bunching up), and the edges don't bother me as much as they first did- there's no rim on the edge, so if you lean your leg against it to control the bike all the pressure is in a thin line (not sure if I just got used to it, or if I'm not leaning on it as hard). I did have to torque down the rails quite a bit though- at 5 Nm I still got creaking and popping and had to tighten more. I don't have a good torque number for where it's at now- not super tight, but definitely more than 5 Nm.
