I've heard that since the logo is embossed that they are prone to stress cracking in that area, as well as being loud and having road wobble (haven't experienced) at higher speeds. I LOVE how it looks, but after hearing the stress cracking at the logo from some people it makes me a bit weary since I put a lot of pressure on the stem since I ride really aggressively.

I just ran across the Cinelli 1R stem, it would go well with my blacked out look I've gone for my bike, but I haven't heard anything about it, is it a good stem?
