    Measuring head angle?

    Being curious I stuck my digital level and a traditional angle finder on the upper fork tube of my XL '11 Trance x2... And I'm getting 68* with both? Is this a correct way to measure?

    I bought this bike used, nothing was said about a mod and Far as I can tell there is no Angleset. The fork angle matches the head tube angle visually. Wondering because I want to put on a height adjustable fork and the larger rear shock, just wanted to keep track of the changes.

    The stock Fox 125RL

    I measured my wife's '12 Anthem the same way and get 71* which is what it should be.

    So how is my Trance measuring 68* when it's supposed to be 69.5*?

    This is about the best straight on pic I've got handy. You can see the fork angle lines up with the head tube...

    my trance gets 67.5 with 140mm fork on it. if the tyres have a higher tread on them then stock items this can also alter the angle as can air pressures i guess.

    Have you zeroed the gauge on the floor first?

    Have they got the correct shock and / or is there an offset bush in the top shock pivot?

    From memory, mine with 650B front wheel and Rev 130 fork is about 68.5?

    Yeah, the gauges are good... I checked them against a triangle square.

    No offset shock parts, rear shock is stock. I just replaced the DU bushing with the roller bearing setup from RWC.

    I have a float 150 and I am getting about 67.5.
    I am surprised that with a 130mm and 650b you are at 68.5.

    I never measured mine stock, but it never seemed that steep even with the 125mm, but feels so right with the 150mm. 140mm is probably ideal.

    I imported the side view of my bike into Autocad. Started drawing lines and measuring angles... HA I get 67.5-68* and STA 71ish.

    I started to doubt the fork today, Just measured the fork and its got 5" of tube showing... So it's still a 125mm fork... I'm confused. What else can I check?
