Yes,Im concidering buying a RST Delta DH DBL crown now Im not looking for the latest and gratest fork my bike is a 98 Schwinn Frontier GS hard tail of corse cheap fun.Now my question is RST Forks are they junk why do you not see lots of them?This fork retailed for $600 when it came out and I can grab this one for say $120 new is this fork upgrade worth it?
No. dont buy it. Your frame is designed for a single crown fork, with up to about 100mm of travel. The headtube area will not be designed for the stresses of a triple clamp, and it'll make the steering awful. Worst of all it'll look really stupid!
if you want a cheap, bombproof fork, get a marzocchi MX comp or EXR. Not sure how much they are over at your end (mainly NZ-AUS, right? I'm in UK) but you can get either for about £120-£150 over here.
