What is the length of the steerer on your Dart 2 KenG? If it's nice & long I maybe interested in swap (I have very long arms!) as I have a pair of as new (fitted then removed only) On-One 26er cromoly forks in pearl white.
They have a full length uncut 1 1/8" ahead steerer and come with the v-brake bosses which cost me £15 extra. Once you've decided how much steerer you wish to cut off you might even be able to bash down the existing starnut which I installed to the correct level for you (although I could supply another starnut free of charge).
I have had them stored away since I split my Rockhopper which I sold with it's original blue forks instead. The a-c measurement is 420mm so they are designed to replace an 80mm suspension fork.
Which exact model is yours? Do they have disc and v-brake mountings? And are they 80mm or 100mm? If the former they'll be a perfect swap, if the latter the On-Ones might quicken your handling a touch. Also, I take it yours only have preload adjustment (no rebound or travel adjustment and no lock-out facility)?
