I did 750 miles yesterday in the new Scheel-Mann 101. Easily the most comfortable seat I've owned. No back pain or sciatic nerve issues like I normally get on road trips.
Made in Germany with OEM supplier build quality (not sure if they're TUV approved but I'd be surprised if they weren't). The welds are beefy and so is the mounting hardware. And Bryan at Achtungkraft designed some fun custom woven fabric and recovered them.
