Yes there was a rather heated
discussion on the crit geometry
I have a Gios compact, which has a geometry something close to what you're looking for. 74* parallel angles and short 39.5cm chainstays (the dropouts are sliding and have some 1cm of fore/aft movement). The BB height however is rather standard at 26.6cm, and so is the rake at 45mm. This puts the trail at around 50mm.
