    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?

    Mas :)

    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...

    Mas :p

    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.
