I believe most of the Sequoias had full alum frames, yours being high end it has the carbon seat stays. Since the rest of the frame is the same alum as the lower-end models, it still has the eyelet holes by the saddle. I would follow the other's suggestions to utilize the eyelets near the saddle and mount to the axle. Old Man Mtn rack. I would probably not use the seat stay lower attachment point even though you could probably do it with longer bolts.
