    Increasing fork length on the same frame

    Does it matter if I run 100mm forks on a frame designed for 80mm forks? obvoisly it will change the ride position a little.

    thank you

    Should be alright~
    But to check, what frame is it?
    And how old is it?
    And what type of riding do you want to do on it?

    Hmmm....

    How long have you used the frame already?
    The headtube/ downtube area looks strong and gusseted, shouldn't be a problem to run that extra 20mm to 100mm....



    Somehow after looking at the picture of the bike, I feel that the bike handling would be a little wierd after putting on a longer fork due to the rise and length of the stock stem....

    If you could run it with a stem with less rise it might just work out....

    If you do wish to try out, please look out for stress marks/cracks at the head tube/downtube area every once in a while, especially when you hear creaking sounds...

    the gy who had it before me said he used it as a poser bike, whether that is true or not is another matter, but I have no intention on jumping it or doing massive drop offs, so i might give it a go for a while. thanks

    I believe you can go up to 100mm and no further... more than that changes the head tube angle substantially & most cross country frames are not designed to deal with the angle of impact associated with say, a 120mm fork. The short story is 100mm or less = golden. Greater than 100mm = cracked headtube.
