I have ridden a Seven Duo and owned a Racer X (both 26”). I preferred the Racer X hands down. When I heard the Duo was going to be available in 29” I checked with my LBS to get an idea of cost. According to what they quoted me, the Asylum should cost almost half as much as the Duo (and the asylum aint cheep). I also find it interesting that Maverick doesn’t think their suspension design is currently adaptable to 29” but Seven does. I say go ahead and get the proprietary shock totally unproven Duo and be the guinea pig for the rest of us.
