I was on the phone with Slavens today and inquired about their suspension setup. Ballpark price is $900-$1100 for the full package, which is rebuilding/revalving the front forks, new spring & rebuild shock in back, tuning to your weight & riding style. Sounds like the deluxe treatment, and something I should do and would benefit from, but probably not this year. Just posting up as an FYI.
