    Hi folks I'm in the process of having a Ti fork made for my bike. The builder asked me for the fork offset measurment. But I just don’t know how to measure that.
    Right now I’m running a Fox 29 with 100mm
    Thanks in advance.

    You can always call Fox and give them the seriel number on the fork. They can look it up for you.

    You might also check what the frame manufacturer suggests for offset on the frame you have.

    I might have to call Fox. I'm guessing my fork to be 2010. It has a straight 1.125 inch steer tube. The link only goes back to 2014.
    Same thing with the frame Lynskey does not make archives accessible.
    Thanks

    I'm just going to guess it at 51mm. Specially if I'll be running 29+ tires

    Why do they sell hot dogs in packs of 10 and buns in packs of 8?

    Part of me thinks that a frame builder should be able to recommend an offset based on the frame geometry and input from the customer. o_O

    @Luis, what does a rake have to do with cycling? I thought it was used in the garden.
