Here goes-for you that have owned or ridden an older Mama. I have an older small Mamasita frame (2008 Scandium) with an older Reba fork, 38 degree offset at 80mm. I find that even though it's older geometry, this thing just rails. It does everything well (except the front end gets a little light on steep climbs). I also have a 2011 EMD (round tubes) but don't think handles nearly as well. What modern frame handles like the Mama?
