Hello. I've been looking for a nicer used 26'er mountain bike and came across a 2010 Sworks Stumpjumper 26er in used, but well taken care of condition that a friend is selling. I don't want to low ball him and was wondering what it be worth, ballpark... Suspension fork functions how it should. Being a 26er it may only appeal to certain buyers, but it was the bees knees in 2010. Hydraulic brakes, SRAM components. Any help would be appreciated..
