    Fork replacement

    Hi,
    I'm considering an upgrade of my kona paddywagon to front disc brake. In order to do so, I'll need to replace my stock Kona Retro Road fork to something like THIS
    My main concern is that stock fork has 375mm axle to crown when cyclocross one is 398.
    Rake is 43mm and 45mm accordingly.
    Would it change my frame geometry significantly? Also, any critique of the project idea or other ways to implement it would be appreciated.
    Thanks,
    -Igor.

    Switching to that Nashbar fork would decrease (slacken) the head tube angle by about 1 degree, which would increase the trail by about 5mm. The slightly higher offset (45 to 43) on the Nashbar fork reduces the change somewhat.

    You will likely notice the change, but the different sizes of paddywagons range from 72 to 73.5 degree HTA, so the change is definitely within the realm of normal.

    Pretty much all road disc forks are 395 or 400mm axle-to-crown, for the record.
    I have a front brake, but I only use it for slowing or stopping.

    I just went through this going from a suspension to a rigid on my mtb. I came to the conclusion that you need to try it. Which usually means buy it.

    I picked up a used fork that I could turn and burn if it did not work. It did.

    The thing is, you might REALLY like the geometry change.

    Thanks for the educated and reasonable answer!

    Um...I've not been on there long enough to know what that means.

    But I am the guy who started the Arione thread for $50? or something close and you bought one.

    It was just alternative meaning of the acronym. Sure, I've recognized you from fv.

    Doh, of course...

    I thought it was an inside joke. Nice to see you on BF though.
