Drew just posted the geometry specs for the MKE S700s on the Bens Blog.
We will be taking pre-orders in 2-3 weeks, full details will be available here shortly.
Sizing: Long top-tubes mean short, stiff stems. So which size is right for you? First, measure your current cockpit (i.e. 54cm top-tube + 110mm stem = 65cm cockpit). The 50cm(S) frame has a 60cm virtual top-tube, so a 50mm stem would get your cockpit @ 65cm.
Keep in mind this frame is designed for 35-90mm stem lengths. It is better to have a shorter seat-tube than a top-tube that is too long.
