    As the title suggests, I am wondering if anyone knows what the head angle would be with a pair of pike like 140mm forks (they’re oem revelations from 07).

    Dialled’s website states 70 degrees and a recommended fork travel of 120-140, but doesn’t particularly state what fork length 70 degrees is measured with.

    I’d appreciate if anyone could answer this question, maybe take the time to measure their own db pa if they have a similar set up.

    About 69 degrees via the unscientific method of an iphone tiltmeter app. 140mm Pikes, can’t remember what year but quite old.

    I think the 70 degrees quoted is for the middle of that range, ie. typical 130mm forks.

    Thanks for the reply and going to the effort to run your phone over it.

    I thought it was originally designed around a fox 125 fork with a A2C of 496mm. I don’t think the geometry has changed bar a bit extra in the top tube. You could calculate it with a bit of trig.
