Going riding today right after work. Hitting the US National whitewater center. Hopefully no going over the bars today.
Looked at the Risseracing.com and they apperantly do susp. work. Going to email them and see if they can do some maint. on the forks....def would depend on the $$$ they charge. Might hold on to the bike for a while and see what kind of money I can spend on it in a couple months.
Cheapest thing I have seen that will match up well in terms of strength, travel, and 20mm through axle ( unless you are changing the front wheel also) is something like the Rockshox Domain.
