    100mm fork on a Surly 1x1?

    Anybody out there running a 100mm fork on a 1x1 frame? I'm thinking of replacing my SISS with a 1x1 frame, but it appears that the 1x1 is built for an 80mm fork. Anybody see any issues running a 100mm fork on a 20 inch 1x1 frame?

    It's possible.

    I ran a Marzocchi MxPro 100mm on my 1x1. I left the fork in the locked down, 60mm position almost all the time except for the descents when it would jack up to the 100mm position. On the descents, 4" felt great. On the flats or ups, the tall fork made the frame feel awkward.
    My wife's 1x1 is running an 80mm F80x now and that seems to be a perfect blend.
    The 1x1 is "suspension corrected" but Surly seems to have corrected it to the old-school 60mm forks anyway...
    Most dudes run the 80mm fork. I think the bike runs best that way, if you aren't running it rigid.

    I run my medium with a Psylo dialed almost half way out. I guess its about 95mm, though I haven't measured it. Doesn't bother me at all, but then again I'm not too picky. I basically started at 80 and then jacked up the front end a little at a time until I didn't like the steering. (Then I put it back down a bit of course.)
    When the going gets weird its bedtime.

    I do

    Although I have only been using it for a couple of days, and today was the first real off-road ride, I think it ranks as "OK". I can notice the angle difference, and plan to switch to an 80mm as soon as I can afford it. I am running a Marzocchi 100mm X-fly.

    The good part is I'm a heavier rider (195-200lb) and my weight tends to preload the fork more than average, so I bet my effective head angle when on the bike is only half the "normal" rake difference between a 100mm and 80mm fork. If that makes any sense.

    I just replaced...

    I just replaced my 105mm fork on my 1x1 with an 80mm fork. Well, I just ordered the 80mm fork. The 105mm just "choppered" it out too much. It would cause the front end to swing around and the brake levers would smack the top tube when I was walking the bike (or if I moved it when I wasn't on the bike).

    my $.02
