I'm building up a hack/pub bike suitable for some half decent offroad riding and have a dilemma on which forks to fit to it. As I'm doing it on the cheap, I have a choice of 2 forks lying about in the garage. An old pair of RST 381 DH triple crown suspension forks or a fairly new pair of Kona Project 2 rigid forks.

The frame is a fairly old Hardrock Comp, no disc brake mounts. Any advice or sensible comments welcome.

Purely on the attraction of the bike to thieving scumbags I'd probably fit the Kona Project 2's....  a big set of suspension forks is going to shout " nick me!"

..although I guess it depends on whether you are planning on really getting into off-road stuff proper on it?

The 381s are old, they'll probably be ready for the scrap heap sooner than the Project 2s.
