What about the Ventana X-5? My S Locomoto had its original frame recalled, and has that X-5 frame, (which is different than the Moto Lite- and the old Loco frame used to be like that Yeti frame that had that curved top tube, which was what I particularly liked about it...) Loco's rear shock connects into the V straight ahead, not downward to the downtube like the X-5, but I don't really know what difference that makes. Anyway, I have a 28" inseam, and have plenty of room on that frame. Ventana's site says the standover is 27.1 on the 15".

Scroll down to see a picture of my Loco frame, like the Ventana frame.
