Right, I've just been out into the workshop and my *findings are;
Summer Season, 100mm Toras = 67 degree head angle
PA, 130mm Drop offs = 69.5 degree head angle
NS Bitch, 170mm 66's = 65 degree head angle
The summer season and PA both ride really well up and down … you only want to be going down on the NS 😉
*Static – no sag.
