Budget fork upgrade for older MTB?
I've had a 2002 Gary Fisher Wahoo since new. Until last year, I had slick tires on it and just rode it around on the street. I have a road bike now and want to return the Wahoo to a MTB. It has a Rock Shox Judy TT 80mm fork on it right now, but i bottom out on the slightest bump. I'm only 180 lbs. The fork is probably the worst part on the bike so I thought I would see about upgrading it a bit.
How would I know what type of replacement fork to look at? Any recommendations in the $100 range, or is that too low for anything decent? I was thinking maybe a take-off from a newer bike?
