true. I for one thing never liked the xs, but love em romeosEveryone has their own preferences and opinions on every frame fit, as they were made to accomidate the general public. The XS is very comfortable, I agree. The R1 has hammerstems also but, fir a little more snug, I believe. The different curravature to the XS earstem gives it a little more temple space. Not by much, but, just enough. I would love to put the XS stems on a Mars. That would look sweet.
