So my Rock Shox fork seals are gone, it was under sprung in the first place, and I think it may have lead to my dislocated shoulder,.

(Probably bad riding was the cause but I can't fix that,. )

Anyway, for mainly xc with the occasional down hill, any suggestions for a smoking deal on a fork? I know i need a 20 mm axle, but what size headset or how do I determine that? I was thinking 6" travel or so to match the rear would work pretty well...

How hard is it to swap a fork? I don't have any bike tools but am somewhat mechanically inclined.

Thanks

AJ
