I went through Speedgoats' bike fit for the Asylum and they recommended the medium. I'm 5-10 with a 33 inch inseam. I spoke to Steve there about a large, since I tend to like a longer TT but they recommended against it. He said the jump between the med and large in terms of SO is pretty big. Check your SO on your current ride, It close to 30 on the medium Asylum. I haven't gotten a frame yet, so I can't speak to how the medium would actually fit me, but hope this info helps.Onetrack said:Just curious how many Asylum riders out there are under 5'8''. The medium frame seems pretty small. Got a riding buddy with a 30.5 inch inseam. How's the fit. Any feedback would be great.
