When you think of the perfect mountain bike, what comes to mind? For us, it's the Spark 910. Why, you ask? Well, beyond the fact that it is fast, lightweight and ultra capable on all sorts of terrain, it's just damned good lookin'. Short-travel trail bike? "Downcountry" rig? Occasional race bike? Whatever, call it what you want to call it. All we know is that this is one hell of a mountain bike.
