Track bike geometry charts - I need help

So I found this interesting article by our very own Don Walker

http://www.urbanvelo.org/issue3/urbanvelo3_p44-45.html

Remembering that he is a forum member I dropped him a line

He wrote back within ten minutes !

He suggested that I needed a trail of ~58cm the article above explains his reasoning for this

His estimation was that to achieve this trail I needed to adjust the headtube angle to 54 degrees

And set the fork rake to 36mm

This I confirmed with this bloody excellent trail/rake calculator

He also suggested raising the BB by a further 0.5cm

Thank you Mr Walker you are a top bloke ...:)

Buddha.

I think you used the wrong side of the calculator?

58 trail you get

75 hta with 30.4 mm fork
74 hta with 36.3 mm fork
73 hta with 42.2 mm fork

'Fast' handling bike track bikes have a trail around 64
