Haven’t measured it exactly but the Marin is somewhere around 70-69 degs.
Orange Five is quoted as 67 with 140mm fork, 66 with a 160mm fork.
Alpine 160 is 66.5 with 160mm fork.
Meta 5 = unsure
666 = unsure.
If I go for either of the 160mm options, i.e. Alpine 160 or the 666 with the pikes, then as suggested above, i assume i’ll not be much better off in terms of head angle than I am at present. Although I note that the 666 is adjustable (not sure in which sense, i.e. does it increase or descrease head angle from the standard setting?).
I would hope that whatever I went for would be a lot stiffer than my present FS.
Being 6″2′ and 16st, the stiffness is very important. So rear maxle essential.
Perhaps the best option is the Five as even with the Pikes I’ll get approx a 2 deg improvement in head angle, with the potential for another degree if/when I can afford the 160mm forks.
In terms of handling, is there much difference between the Orange & Meta?
